How to use the bash for loop: Syntax and examples Dec 22, 2025 / Edward S. & Aris S. / 8min read A Bash for loop is a statement in the Bash programming language that allows a code or script to run repeatedly. It enables you to finish repetitive tasks simultaneously, which helps improve system management efficiency.  A Bash for loop works by assigning items in a list to a variable and executing an operation for each of them. The basic syntax is as follows: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done In a real-world scenario, a Bash for loop has various implementations, often involving other programming concepts. For example, you can use a Bash for loop to create a three-expression loop, an infinite loop, a start-and-stop sequence, and more.  Continue reading to learn more about a Bash for loop and its practical usage examples.  Download comprehensive bash cheat sheet A Bash for loop is a construction that lets you run a set of commands repeatedly on multiple items with a single execution. It is helpful for automating repetitive operations, such as renaming files, in a command-line-based system like a Linux virtual private server (VPS). The logic behind a Bash for loop is as follows: a set of commands will continue to run in a loop for each item listed in the variable. This loop ends after running the operation for the last item. Simply put, you can interpret it as for each item assigned to the variable, loop the same set of commands. However, you can incorporate conditional statements to modify how the loop will run. Let’s explore the syntax of a Bash for loop line by line in the next section to better understand about how it works. What is the syntax of a Bash for loop? The Bash for loop executes a set of commands repeatedly, with the loop iterating through a sequence of items or values. The syntax of such an operation looks like this: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done In the real world, this syntax would look like the example below: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter #!/bin/bash for i in 1 2 3 4 5 do echo "Hello $i" done #!/bin/bash for i in 1 2 3 4 5 do echo "Hello $i" done #!/bin/bash for i in 1 2 3 4 5 do echo "Hello $i" done Executing the bash file will cause the following sequence: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 Let’s inspect each element: #!/bin/bash – shows that the code is a bash script. i – is a placeholder for a variable. Meanwhile, $i is the individual value of the variable. You can also write it as c/$c or by any other name. in – separates the variable and the items that follow. 1 2 3 4 5 – is an example of items you want to perform the instruction on. do – is the keyword that starts the loops. It will then execute the instruction n times, with n being the total number of items. Here, the value of n is 5 . echo “Hello: $i “ – is the Linux command or operation we will repeat n times. Remember, quotation marks turn anything inside it into one variable. done – stops the loop. The other two common loop command syntaxes are this: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for VARIABLE in file1 file2 file3 do command1 on $VARIABLE command2 commandN done for VARIABLE in file1 file2 file3 do command1 on $VARIABLE command2 commandN done for VARIABLE in file1 file2 file3 do command1 on $VARIABLE command2 commandN done And this: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for OUTPUT in $ (Linux-Or-Unix-Command-Here) do command1 on $OUTPUT command2 on $OUTPUT commandN done for OUTPUT in $(Linux-Or-Unix-Command-Here) do command1 on $OUTPUT command2 on $OUTPUT commandN done for OUTPUT in $(Linux-Or-Unix-Command-Here) do command1 on $OUTPUT command2 on $OUTPUT commandN done Now that we understand the Bash for loop syntax, let’s explore examples of how the actual script looks in real-life applications. What are the examples of a Bash for loop? Here are Bash for loop examples used to perform multiple operations. If you wish to follow along, you’ll have to log into your VPS. If you’re having trouble, read our Putty SSH tutorial to learn more about how to do so. Remember that bash functions need to be in a .sh file . To create one, run the following in the command line: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter vim filename. sh vim filename.sh vim filename.sh This will create a .sh file, and will open it in the VIM editor. You can learn more in the previously mentioned basic bash function article. How to use a Bash for loop with a number Using a Bash for loop with numbers lets you iterate through a range instead of specifying the items individually. To do this, add the range in curly braces separated by double dots. For example, the following loop will echo all numbers from one to five: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in {1.. 5 } do echo "$i" done for i in {1..5} do echo "$i" done for i in {1..5} do echo "$i" done You can also change the increment using the {START..END..INCREMENT} three-expression syntax. Here’s the code example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in {1..10.. 2 } do echo "Number: $i" done for i in {1..10..2} do echo "Number: $i" done for i in {1..10..2} do echo "Number: $i" done Important! In some scripts, the increment syntax uses double parentheses instead of curly braces. Regardless, both have the same function. The loop will operate on the first value of 1 , move up by two increments to 3 , and so on. Once it reaches the end value of 10 , the code will stop. Here’s the output: Note that the range feature is only available in Bash version 3.0 or later, while the increment is supported in Bash 4.0 and newer. How to use a Bash for loop with array elements Combining a Bash for loop with an array iterates over elements grouped together and executes a set of commands for each of them. Instead of using a list, incorporating arrays into Bash makes your script more organized and easily readable, especially when you want to use many items. To use a Bash for loop with an array, declare the array and its items at the beginning. Then, add it to your for-in expression like so: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter #Declare an array of items array =( "item1" "item2" "item3" "item4" ) #Iterate through the array and apply the operations for item in "${array[@]}" do command1 command2 command3 done #Declare an array of items array=("item1" "item2" "item3" "item4") #Iterate through the array and apply the operations for item in "${array[@]}" do command1 command2 command3 done #Declare an array of items array=("item1" "item2" "item3" "item4") #Iterate through the array and apply the operations for item in "${array[@]}" do command1 command2 command3 done Here’s an example of a Bash for loop with array elements, using fruits as the items: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter fruit_array =( "apple" "banana" "red cherry" "green grape" ) for fruit in "${fruit_array[@]}" do echo "Fruit: $fruit" done fruit_array=("apple" "banana" "red cherry" "green grape") for fruit in "${fruit_array[@]}" do echo "Fruit: $fruit" done fruit_array=("apple" "banana" "red cherry" "green grape") for fruit in "${fruit_array[@]}" do echo "Fruit: $fruit" done The bash loop will iterate through items in the array and use the echo command to print them with the Fruit: prefix. This is what the output looks like: If you add another command, the loop will operate on the same item before moving to the next one. For example, we’ll insert another echo to add a suffix to the item. Here’s the output: How to use a Bash for loop with a shell variable Combining a Bash for loop with a shell variable enables you to store items that your code will iterate through. It works similarly to an array in that you group multiple elements, but it uses spaces to split the entries. A Bash for loop with a shell variable uses the following syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter #Define the shell variable variable = "a single item" #Iterate through the variable and apply the operations for item in $variable do command1 command2 command3 done #Define the shell variable variable="a single item" #Iterate through the variable and apply the operations for item in $variable do command1 command2 command3 done #Define the shell variable variable="a single item" #Iterate through the variable and apply the operations for item in $variable do command1 command2 command3 done The shell variable only contains one data element, but the Bash loop automatically iterates through space-separated items, treating them as different entities. Consider this example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter var_numbers = "1 2 3 4 5" for number in $var_numbers do echo "Number: $number" done var_numbers="1 2 3 4 5" for number in $var_numbers do echo "Number: $number" done var_numbers="1 2 3 4 5" for number in $var_numbers do echo "Number: $number" done Instead of printing the numbers as a string, the bash loop will print them individually because they are separated by a space. To treat the items as a single entity, enclose the $var_numbers variable in the for-in expression with quotation marks, like the following: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for number in "$var_numbers" for number in "$var_numbers" for number in "$var_numbers" You can change the behavior of Bash variables to change the loop output. To learn more about it, check out our bash variables tutorial. How to use a Bash for loop with strings Combining a Bash for loop with strings enables you to iterate through text for operations like concatenating , which is typically grouped into a shell variable or array. Using a shell variable is common if your strings are not separated by a space, like the following syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter variable = "string1 string2 string3" for item in $variable do command1 command2 command3 done variable="string1 string2 string3" for item in $variable do command1 command2 command3 done variable="string1 string2 string3" for item in $variable do command1 command2 command3 done Meanwhile, use a Bash for loop with strings grouped into an array if your string contains whitespace. In addition to allowing the bash loop to read space-separated items, they are easier to iterate over and expand. Here’s the syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter array =( "First item" "Second item" "Third item" "Fourth item" ) for item in "${array[@]}" do command1 command2 command3 done array=("First item" "Second item" "Third item" "Fourth item") for item in "${array[@]}" do command1 command2 command3 done array=("First item" "Second item" "Third item" "Fourth item") for item in "${array[@]}" do command1 command2 command3 done How to use a Bash for loop to create a three-expression loop Using a Bash for loop to create a three-expression loop uses a structure similar to the C programming language. This structure is comprised of three writing expressions – an initializer ( EXP1 ), a condition ( EXP2 ), and a counting step ( EXP3 ). The initializer sets the initial script variable, and the condition determines whether or not the loop continues. Meanwhile, the counting step alters the initial value until it meets the specified condition. The syntax of this loop is as follows: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done For a better understanding, consider the following code example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter #!/bin/bash for (( c= 1 ; c<= 5 ; c++ )) do echo "The number $c" done #!/bin/bash for (( c=1; c<=5; c++ )) do echo "The number $c" done #!/bin/bash for (( c=1; c<=5; c++ )) do echo "The number $c" done The code sets the loop’s initial value as 1 . The loop will run as long as the condition in EXP2 is true – the code variable shouldn’t be bigger than 5 . The counting expression has the ++ sign, which increments the initial value by one each time the loop runs. The bash script will echo a message “ $c ” which refers to the loop value, starting from 1 until it reaches the specified condition. The output will be as follows: How to use a Bash for loop to create an infinite loop Creating an infinity loop using a Bash for loop lets you execute code indefinitely until you terminate the process manually by pressing Ctrl + C . There are different ways to do so, such as using the while expression: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter while true do echo "Hello, world!" sleep 1 done while true do echo "Hello, world!" sleep 1 done while true do echo "Hello, world!" sleep 1 done When the condition is true , the command will print the Hello, world! message with a one-second delay. The snippet uses the while true conditional statement to enable the code to always return the successful exit status. Since the condition remains true , the code will keep looping the echo command to print the message. Another method is to use the three-expression infinite loop: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for (( ; ; )) do echo "Hello, world!" sleep 1 done for (( ; ; )) do echo "Hello, world!" sleep 1 done for (( ; ; )) do echo "Hello, world!" sleep 1 done In the snippet, we set all the expressions to empty. Since there’s no termination condition to meet, the loop will continue until the user stops it. How to use a Bash for loop to create the skip and continue loop A Bash for loop lets you create a loop that skips a specific value and continues running afterward. This operation uses the following syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in 1 2 3 4 5 do if [condition] then #Continue with the next iteration of i and skip the statement continue fi statement done for i in 1 2 3 4 5 do if [condition] then #Continue with the next iteration of i and skip the statement continue fi statement done for i in 1 2 3 4 5 do if [condition] then #Continue with the next iteration of i and skip the statement continue fi statement done Here’s a skip-and-continue loop code example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in {1.. 5 } do if [[ "$i" == '4' ]] then continue fi echo "Hello $i" done for i in {1..5} do if [[ "$i" == '4' ]] then continue fi echo "Hello $i" done for i in {1..5} do if [[ "$i" == '4' ]] then continue fi echo "Hello $i" done In the snippet, we define the items to modify as numbers one to five. We add an if condition, stating that when the variable value equals 4 , the loop doesn’t run the code and continues to the next value. It means the loop will operate on 1 , 2 , 3 , and 5 , as the output shows: How to use a Bash for loop to create a conditional exit with break loop A Bash for loop lets you create a loop that automatically stops when it meets a specific condition. using the for-in construct like this syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in 1 2 3 4 5 do if [condition] then break fi statement done for i in 1 2 3 4 5 do if [condition] then break fi statement done for i in 1 2 3 4 5 do if [condition] then break fi statement done You can add another command at the end of the code, which will run after the loop ends. Consider the following example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for state in Alabama Alaska Arizona Arkansas California do if [[ "$state" == 'Arkansas' ]]; then break fi echo "state: $state" done echo 'That’s all!' for state in Alabama Alaska Arizona Arkansas California do if [[ "$state" == 'Arkansas' ]]; then break fi echo "state: $state" done echo 'That’s all!' for state in Alabama Alaska Arizona Arkansas California do if [[ "$state" == 'Arkansas' ]]; then break fi echo "state: $state" done echo 'That’s all!' The loop script prints all state names specified in the list but stops once the break condition is met, namely when the current value equals Arkansas . Then, it moves to the next instruction to echo the That’s all! message. Here’s what the output looks like: How to effectively use a Bash script in Hostinger VPS Using a Bash for loop with your web hosting provider’s features can further simplify your server administration tasks, making it more efficient. For example, Hostinger VPS plans have a browser terminal built into our hosting custom control panel, hPanel. It lets you run Linux commands and utilities like bash loop directly from your web browser. We have an AI agent, Kodee , that simplifies VPS management for beginners. For example, you can ask it to generate Bash for loop scripts for various tasks using simple prompts like “Can you generate a Bash for loop that restarts a list of services?” or “Please create a Bash for loop to back up multiple directories.” To access the tool, log in to hPanel and click on VPS in the top menu. Select the applicable server and navigate to Kodee in the sidebar. To get accurate results, ensure your web development AI prompts are specific and clear. Check out our AI prompts for VPS management guide to learn more about using Kodee for various tasks. Important! Due to AI limitations, some answers may be inaccurate or obsolete. Key takeaways A Bash for loop is great for automating repetitive tasks, processing data, and managing a UNIX-like system. For example, with a single execution, you can iterate through names to automatically create new users when setting up a new VPS . As explained, you can perform various assignments with a Bash for loop by combining it with other Bash constructs, like for-in . You can further expand its functionality by incorporating other command-line tools to create an efficient way to complete a task.

Let’s explore the syntax of a Bash for loop line by line in the next section to better understand about how it works. ## What is the syntax of a Bash for loop? The Bash for loop executes a set of commands repeatedly, with the loop iterating through a sequence of items or values. The syntax of such an operation looks like this: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for VARIABLE in 1 2 3 4 5 ..

N Perform the below command: command1 command2 commandN done ``` In the real world, this syntax would look like the example below: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter \#!/bin/bash for i in 1 2 3 4 5 do echo "Hello \$i" done \#!/bin/bash for i in 1 2 3 4 5 do echo "Hello \$i" done ``` #!/bin/bash for i in 1 2 3 4 5 do echo "Hello $i" done ``` Executing the bash file will cause the following sequence: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 ``` Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 ``` Let’s inspect each element: - **\#!/bin/bash –** shows that the code is a bash script. - **i** – is a placeholder for a variable. Meanwhile, **\$i** is the individual value of the variable. You can also write it as **c/\$c** or by any other name. - **in** – separates the variable and the items that follow. - **1 2 3 4 5** – is an example of items you want to perform the instruction on. - **do** – is the keyword that starts the loops. It will then execute the instruction **n** times, with **n** being the total number of items. Here, the value of **n** is **5**. - **echo “Hello: \$i**“**** – is the [Linux command](https://www.hostinger.com/tutorials/linux-commands) or operation we will repeat **n** times. Remember, quotation marks turn anything inside it into one variable. - **done** – stops the loop. The other two common loop command syntaxes are this: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for VARIABLE in file1 file2 file3 do command1 on \$VARIABLE command2 commandN done for VARIABLE in file1 file2 file3 do command1 on \$VARIABLE command2 commandN done ``` for VARIABLE in file1 file2 file3 do command1 on $VARIABLE command2 commandN done ``` And this: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for OUTPUT in \$(Linux-Or-Unix-Command-Here) do command1 on \$OUTPUT command2 on \$OUTPUT commandN done for OUTPUT in \$(Linux-Or-Unix-Command-Here) do command1 on \$OUTPUT command2 on \$OUTPUT commandN done ``` for OUTPUT in $(Linux-Or-Unix-Command-Here) do command1 on $OUTPUT command2 on $OUTPUT commandN done ``` [![](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2023/02/VPS-hosting-banner.png/public)](https://www.hostinger.com/vps-hosting) Now that we understand the Bash for loop syntax, let’s explore examples of how the actual script looks in real-life applications. ## **What are the examples of a Bash for loop?** Here are Bash for loop examples used to perform multiple operations. If you wish to follow along, you’ll have to log into your VPS. If you’re having trouble, read our [Putty SSH tutorial](https://www.hostinger.com/tutorials/how-to-use-putty-ssh) to learn more about how to do so. Remember that bash functions need to be in a [**.sh** file](https://www.hostinger.com/tutorials/how-to-run-sh-file-in-linux). To create one, run the following in the command line: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter vim filename.sh vim filename.sh ``` vim filename.sh ``` This will create a .sh file, and will open it in the VIM editor. You can learn more in the previously mentioned basic bash function article. ### **How to use a Bash for loop with a number** Using a Bash for loop with numbers lets you iterate through a range instead of specifying the items individually. To do this, add the range in curly braces separated by double dots. For example, the following loop will echo all numbers from one to five: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in {1..5} do echo "\$i" done for i in {1..5} do echo "\$i" done ``` for i in {1..5} do echo "$i" done ``` You can also change the increment using the **{START..END..INCREMENT}** three-expression syntax. Here’s the code example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in {1..10..2} do echo "Number: \$i" done for i in {1..10..2} do echo "Number: \$i" done ``` for i in {1..10..2} do echo "Number: $i" done ``` **Important\!** In some scripts, the increment syntax uses double parentheses instead of curly braces. Regardless, both have the same function. The loop will operate on the first value of **1**, move up by two increments to **3**,and so on. Once it reaches the end value of **10**, the code will stop. Here’s the output: [![The bash for loop with increment output](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/bash-loop-with-increment-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/bash-loop-with-increment-output.png) Note that the range feature is only available in **Bash version 3.0** or later, while the increment is supported in **Bash 4.0** and newer. ### **How to use a Bash for loop with array elements** Combining a Bash for loop with an array iterates over elements grouped together and executes a set of commands for each of them. Instead of using a list, [incorporating arrays into Bash](https://www.hostinger.com/tutorials/bash-array) makes your script more organized and easily readable, especially when you want to use many items. To use a Bash for loop with an array, declare the array and its items at the beginning. Then, add it to your for-in expression like so: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter \#Declare an array of items array\=("item1" "item2" "item3" "item4") \#Iterate through the array and apply the operations for item in "\${array\[@\]}" do command1 command2 command3 done \#Declare an array of items array=("item1" "item2" "item3" "item4") \#Iterate through the array and apply the operations for item in "\${array\[@\]}" do command1 command2 command3 done ``` #Declare an array of items array=("item1" "item2" "item3" "item4") #Iterate through the array and apply the operations for item in "${array[@]}" do command1 command2 command3 done ``` Here’s an example of a Bash for loop with array elements, using fruits as the items: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter fruit\_array\=("apple" "banana" "red cherry" "green grape") for fruit in "\${fruit\_array\[@\]}" do echo "Fruit: \$fruit" done fruit\_array=("apple" "banana" "red cherry" "green grape") for fruit in "\${fruit\_array\[@\]}" do echo "Fruit: \$fruit" done ``` fruit_array=("apple" "banana" "red cherry" "green grape") for fruit in "${fruit_array[@]}" do echo "Fruit: $fruit" done ``` The bash loop will iterate through items in the array and use the **echo** command to print them with the **Fruit:** prefix. This is what the output looks like: [![The output of bash for loop with an array](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/bash-loop-with-array-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/bash-loop-with-array-output.png) If you add another command, the loop will operate on the same item before moving to the next one. For example, we’ll insert another **echo** to add a suffix to the item. Here’s the output: [![The output of a bash for loop with an array and two operations](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/bash-for-loop-with-array-and-two-operations-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/bash-for-loop-with-array-and-two-operations-output.png) ### **How to use a Bash for loop with a shell variable** Combining a Bash for loop with a shell variable enables you to store items that your code will iterate through. It works similarly to an array in that you group multiple elements, but it uses spaces to split the entries. A Bash for loop with a shell variable uses the following syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter \#Define the shell variable variable\="a single item" \#Iterate through the variable and apply the operations for item in \$variable do command1 command2 command3 done \#Define the shell variable variable="a single item" \#Iterate through the variable and apply the operations for item in \$variable do command1 command2 command3 done ``` #Define the shell variable variable="a single item" #Iterate through the variable and apply the operations for item in $variable do command1 command2 command3 done ``` The shell variable only contains one data element, but the Bash loop automatically iterates through space-separated items, treating them as different entities. Consider this example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter var\_numbers\="1 2 3 4 5" for number in \$var\_numbers do echo "Number: \$number" done var\_numbers="1 2 3 4 5" for number in \$var\_numbers do echo "Number: \$number" done ``` var_numbers="1 2 3 4 5" for number in $var_numbers do echo "Number: $number" done ``` Instead of printing the numbers as a string, the bash loop will print them individually because they are separated by a space. To treat the items as a single entity, enclose the **\$var\_numbers** variable in the **for-in** expression with quotation marks, like the following: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for number in "\$var\_numbers" for number in "\$var\_numbers" ``` for number in "$var_numbers" ``` [![The output of a bash for loop with a single-item variable](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2023/09/bash-loop-with-single-item-variable-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2023/09/bash-loop-with-single-item-variable-output.png) You can change the behavior of Bash variables to change the loop output. To learn more about it, check out our [bash variables](https://www.hostinger.com/tutorials/bash-variables) tutorial. ### **How to use a Bash for loop with strings** Combining a Bash for loop with strings enables you to iterate through text for operations like [concatenating](https://www.hostinger.com/tutorials/bash-concatenate-strings), which is typically grouped into a shell variable or array. Using a shell variable is common if your strings are not separated by a space, like the following syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter variable\="string1 string2 string3" for item in \$variable do command1 command2 command3 done variable="string1 string2 string3" for item in \$variable do command1 command2 command3 done ``` variable="string1 string2 string3" for item in $variable do command1 command2 command3 done ``` Meanwhile, use a Bash for loop with strings grouped into an array if your string contains whitespace. In addition to allowing the bash loop to read space-separated items, they are easier to iterate over and expand. Here’s the syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter array\=("First item" "Second item" "Third item" "Fourth item") for item in "\${array\[@\]}" do command1 command2 command3 done array=("First item" "Second item" "Third item" "Fourth item") for item in "\${array\[@\]}" do command1 command2 command3 done ``` array=("First item" "Second item" "Third item" "Fourth item") for item in "${array[@]}" do command1 command2 command3 done ``` ### **How to use a Bash for loop to create a three-expression loop** Using a Bash for loop to create a three-expression loop uses a structure similar to the C programming language. This structure is comprised of three writing expressions – an initializer (**EXP1**), a condition (**EXP2**), and a counting step (**EXP3**). The initializer sets the initial script variable, and the condition determines whether or not the loop continues. Meanwhile, the counting step alters the initial value until it meets the specified condition. The syntax of this loop is as follows: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done ``` for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done ``` For a better understanding, consider the following code example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter \#!/bin/bash for (( c=1; c\<=5; c++ )) do echo "The number \$c" done \#!/bin/bash for (( c=1; c\<=5; c++ )) do echo "The number \$c" done ``` #!/bin/bash for (( c=1; c<=5; c++ )) do echo "The number $c" done ``` The code sets the loop’s initial value as **1**. The loop will run as long as the condition in **EXP2** is true – the code variable shouldn’t be bigger than **5**. The counting expression has the **\++** sign, which increments the initial value by one each time the loop runs. The bash script will echo a message “**\$c**” which refers to the loop value, starting from **1** until it reaches the specified condition. The output will be as follows: [![The three-expression bash for loop output](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/three-expression-bash-loop-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/three-expression-bash-loop-output.png) ### **How to use a Bash for loop to create an infinite loop** Creating an infinity loop using a Bash for loop lets you execute code indefinitely until you terminate the process manually by pressing **Ctrl + C**.There are different ways to do so, such as using the **while** expression: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter while true do echo "Hello, world!" sleep 1 done while true do echo "Hello, world!" sleep 1 done ``` while true do echo "Hello, world!" sleep 1 done ``` When the condition is **true**, the command will print the **Hello, world\!** message with a one-second delay. The snippet uses the **while true** conditional statement to enable the code to always return the successful exit status. Since the condition remains **true**, the code will keep looping the [**echo** command](https://www.hostinger.com/tutorials/echo-command-linux) to print the message. Another method is to use the three-expression infinite loop: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for (( ; ; )) do echo "Hello, world!" sleep 1 done for (( ; ; )) do echo "Hello, world!" sleep 1 done ``` for (( ; ; )) do echo "Hello, world!" sleep 1 done ``` In the snippet, we set all the expressions to empty. Since there’s no termination condition to meet, the loop will continue until the user stops it. [![The infinite bash for loop output](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/infinite-bash-loop-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/infinite-bash-loop-output.png) ### **How to use a Bash for loop to create the skip and continue loop** A Bash for loop lets you create a loop that skips a specific value and continues running afterward. This operation uses the following syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in 1 2 3 4 5 do if \[condition\] then \#Continue with the next iteration of i and skip the statement continue fi statement done for i in 1 2 3 4 5 do if \[condition\] then \#Continue with the next iteration of i and skip the statement continue fi statement done ``` for i in 1 2 3 4 5 do if [condition] then #Continue with the next iteration of i and skip the statement continue fi statement done ``` Here’s a skip-and-continue loop code example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in {1..5} do if \[\[ "\$i" == '4' \]\] then continue fi echo "Hello \$i" done for i in {1..5} do if \[\[ "\$i" == '4' \]\] then continue fi echo "Hello \$i" done ``` for i in {1..5} do if [[ "$i" == '4' ]] then continue fi echo "Hello $i" done ``` In the snippet, we define the items to modify as numbers one to five. We add an **if** condition, stating that when the variable value equals **4**, the loop doesn’t run the code and continues to the next value. It means the loop will operate on **1**, **2**, **3**, and **5**, as the output shows: [![The skip-continue bash loop output](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/skip-continue-bash-loop-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/skip-continue-bash-loop-output.png) ### **How to use a Bash for loop to create a conditional exit with break loop** A Bash for loop lets you create a loop that automatically stops when it meets a specific condition. using the **for-in** construct like this syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in 1 2 3 4 5 do if \[condition\] then break fi statement done for i in 1 2 3 4 5 do if \[condition\] then break fi statement done ``` for i in 1 2 3 4 5 do if [condition] then break fi statement done ``` You can add another command at the end of the code, which will run after the loop ends. Consider the following example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for state in Alabama Alaska Arizona Arkansas California do if \[\[ "\$state" == 'Arkansas' \]\]; then break fi echo "state: \$state" done echo 'That’s all!' for state in Alabama Alaska Arizona Arkansas California do if \[\[ "\$state" == 'Arkansas' \]\]; then break fi echo "state: \$state" done echo 'That’s all!' ``` for state in Alabama Alaska Arizona Arkansas California do if [[ "$state" == 'Arkansas' ]]; then break fi echo "state: $state" done echo 'That’s all!' ``` The loop script prints all state names specified in the list but stops once the break condition is met, namely when the current value equals **Arkansas**. Then, it moves to the next instruction to echo the **That’s all\!** message. Here’s what the output looks like: [![The output of bash loop with break conditional exit](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/bash-loop-break-condition-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/bash-loop-break-condition-output.png) ### **How to effectively use a Bash script in Hostinger VPS** Using a Bash for loop with your web hosting provider’s features can further simplify your server administration tasks, making it more efficient. For example, Hostinger VPS plans have a **browser terminal** built into our hosting custom control panel, hPanel. It lets you run Linux commands and utilities like bash loop directly from your web browser. [![](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2023/02/VPS-hosting-banner.png/public)](https://www.hostinger.com/vps-hosting) We have an AI agent, **Kodee**, that simplifies VPS management for beginners. For example, you can ask it to generate Bash for loop scripts for various tasks using simple prompts like “Can you generate a Bash for loop that restarts a list of services?” or “Please create a Bash for loop to back up multiple directories.” ![Kodee generates a bash for loop script based on a user request](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/kodee-generates-a-bash-for-loop-script.png/public) To access the tool, log in to hPanel and click on **VPS** in the top menu. Select the applicable server and navigate to **Kodee** in the sidebar. To get accurate results, ensure your [web development AI prompts](https://www.hostinger.com/tutorials/ai-prompts-for-web-developers) are specific and clear. Check out our [AI prompts for VPS management](https://www.hostinger.com/tutorials/ai-prompts-for-vps-management) guide to learn more about using **Kodee** for various tasks. **Important\!** Due to AI limitations, some answers may be inaccurate or obsolete. ## Key takeaways A Bash for loop is great for automating repetitive tasks, processing data, and managing a UNIX-like system. For example, with a single execution, you can iterate through names to automatically create new users when [setting up a new VPS](https://www.hostinger.com/tutorials/how-to-set-up-vps). As explained, you can perform various assignments with a Bash for loop by combining it with other Bash constructs, like **for-in**. You can further expand its functionality by incorporating other command-line tools to create an efficient way to complete a task. Now that you understand the basics of a Bash for loop, it’s time to practice using it in day-to-day tasks. If you use Hostinger VPS, asking **Kodee** to write or break down Bash for loop scripts makes the learning process more intuitive, helping you familiarize yourself with it more quickly.

## How to use the bash for loop: Syntax and examples Dec 22, 2025 / Edward S. & Aris S. / 8min read A **Bash for loop** is a statement in the Bash programming language that allows a code or script to run repeatedly. It enables you to finish repetitive tasks simultaneously, which helps improve system management efficiency. A Bash for loop works by assigning items in a list to a variable and executing an operation for each of them. The basic syntax is as follows: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done ``` for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done ``` In a real-world scenario, a Bash for loop has various implementations, often involving other programming concepts. For example, you can use a Bash for loop to create a three-expression loop, an infinite loop, a start-and-stop sequence, and more. Continue reading to learn more about a Bash for loop and its practical usage examples. [Download comprehensive bash cheat sheet](https://assets.hostinger.com/content/tutorials/pdf/Bash-Cheat-Sheet.pdf) A Bash for loop is a construction that lets you run a set of commands repeatedly on multiple items with a single execution. It is helpful for automating repetitive operations, such as renaming files, in a command-line-based system like a [Linux virtual private server](https://www.hostinger.com/vps-hosting) (VPS). The logic behind a Bash for loop is as follows: a set of commands will continue to run in a loop for each item listed in the variable. This loop ends after running the operation for the last item. Simply put, you can interpret it as **for** each item assigned to the variable, **loop** the same set of commands. However, you can incorporate conditional statements to modify how the loop will run. Let’s explore the syntax of a Bash for loop line by line in the next section to better understand about how it works. ## What is the syntax of a Bash for loop? The Bash for loop executes a set of commands repeatedly, with the loop iterating through a sequence of items or values. The syntax of such an operation looks like this: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done ``` for VARIABLE in 1 2 3 4 5 .. N Perform the below command: command1 command2 commandN done ``` In the real world, this syntax would look like the example below: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter \#!/bin/bash for i in 1 2 3 4 5 do echo "Hello \$i" done \#!/bin/bash for i in 1 2 3 4 5 do echo "Hello \$i" done ``` #!/bin/bash for i in 1 2 3 4 5 do echo "Hello $i" done ``` Executing the bash file will cause the following sequence: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 ``` Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 ``` Let’s inspect each element: - **\#!/bin/bash –** shows that the code is a bash script. - **i** – is a placeholder for a variable. Meanwhile, **\$i** is the individual value of the variable. You can also write it as **c/\$c** or by any other name. - **in** – separates the variable and the items that follow. - **1 2 3 4 5** – is an example of items you want to perform the instruction on. - **do** – is the keyword that starts the loops. It will then execute the instruction **n** times, with **n** being the total number of items. Here, the value of **n** is **5**. - **echo “Hello: \$i**“**** – is the [Linux command](https://www.hostinger.com/tutorials/linux-commands) or operation we will repeat **n** times. Remember, quotation marks turn anything inside it into one variable. - **done** – stops the loop. The other two common loop command syntaxes are this: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for VARIABLE in file1 file2 file3 do command1 on \$VARIABLE command2 commandN done for VARIABLE in file1 file2 file3 do command1 on \$VARIABLE command2 commandN done ``` for VARIABLE in file1 file2 file3 do command1 on $VARIABLE command2 commandN done ``` And this: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for OUTPUT in \$(Linux-Or-Unix-Command-Here) do command1 on \$OUTPUT command2 on \$OUTPUT commandN done for OUTPUT in \$(Linux-Or-Unix-Command-Here) do command1 on \$OUTPUT command2 on \$OUTPUT commandN done ``` for OUTPUT in $(Linux-Or-Unix-Command-Here) do command1 on $OUTPUT command2 on $OUTPUT commandN done ``` [![](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2023/02/VPS-hosting-banner.png/public)](https://www.hostinger.com/vps-hosting) Now that we understand the Bash for loop syntax, let’s explore examples of how the actual script looks in real-life applications. ## **What are the examples of a Bash for loop?** Here are Bash for loop examples used to perform multiple operations. If you wish to follow along, you’ll have to log into your VPS. If you’re having trouble, read our [Putty SSH tutorial](https://www.hostinger.com/tutorials/how-to-use-putty-ssh) to learn more about how to do so. Remember that bash functions need to be in a [**.sh** file](https://www.hostinger.com/tutorials/how-to-run-sh-file-in-linux). To create one, run the following in the command line: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter vim filename.sh vim filename.sh ``` vim filename.sh ``` This will create a .sh file, and will open it in the VIM editor. You can learn more in the previously mentioned basic bash function article. ### **How to use a Bash for loop with a number** Using a Bash for loop with numbers lets you iterate through a range instead of specifying the items individually. To do this, add the range in curly braces separated by double dots. For example, the following loop will echo all numbers from one to five: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in {1..5} do echo "\$i" done for i in {1..5} do echo "\$i" done ``` for i in {1..5} do echo "$i" done ``` You can also change the increment using the **{START..END..INCREMENT}** three-expression syntax. Here’s the code example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in {1..10..2} do echo "Number: \$i" done for i in {1..10..2} do echo "Number: \$i" done ``` for i in {1..10..2} do echo "Number: $i" done ``` **Important\!** In some scripts, the increment syntax uses double parentheses instead of curly braces. Regardless, both have the same function. The loop will operate on the first value of **1**, move up by two increments to **3**,and so on. Once it reaches the end value of **10**, the code will stop. Here’s the output: [![The bash for loop with increment output](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/bash-loop-with-increment-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/bash-loop-with-increment-output.png) Note that the range feature is only available in **Bash version 3.0** or later, while the increment is supported in **Bash 4.0** and newer. ### **How to use a Bash for loop with array elements** Combining a Bash for loop with an array iterates over elements grouped together and executes a set of commands for each of them. Instead of using a list, [incorporating arrays into Bash](https://www.hostinger.com/tutorials/bash-array) makes your script more organized and easily readable, especially when you want to use many items. To use a Bash for loop with an array, declare the array and its items at the beginning. Then, add it to your for-in expression like so: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter \#Declare an array of items array\=("item1" "item2" "item3" "item4") \#Iterate through the array and apply the operations for item in "\${array\[@\]}" do command1 command2 command3 done \#Declare an array of items array=("item1" "item2" "item3" "item4") \#Iterate through the array and apply the operations for item in "\${array\[@\]}" do command1 command2 command3 done ``` #Declare an array of items array=("item1" "item2" "item3" "item4") #Iterate through the array and apply the operations for item in "${array[@]}" do command1 command2 command3 done ``` Here’s an example of a Bash for loop with array elements, using fruits as the items: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter fruit\_array\=("apple" "banana" "red cherry" "green grape") for fruit in "\${fruit\_array\[@\]}" do echo "Fruit: \$fruit" done fruit\_array=("apple" "banana" "red cherry" "green grape") for fruit in "\${fruit\_array\[@\]}" do echo "Fruit: \$fruit" done ``` fruit_array=("apple" "banana" "red cherry" "green grape") for fruit in "${fruit_array[@]}" do echo "Fruit: $fruit" done ``` The bash loop will iterate through items in the array and use the **echo** command to print them with the **Fruit:** prefix. This is what the output looks like: [![The output of bash for loop with an array](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/bash-loop-with-array-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/bash-loop-with-array-output.png) If you add another command, the loop will operate on the same item before moving to the next one. For example, we’ll insert another **echo** to add a suffix to the item. Here’s the output: [![The output of a bash for loop with an array and two operations](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/bash-for-loop-with-array-and-two-operations-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/bash-for-loop-with-array-and-two-operations-output.png) ### **How to use a Bash for loop with a shell variable** Combining a Bash for loop with a shell variable enables you to store items that your code will iterate through. It works similarly to an array in that you group multiple elements, but it uses spaces to split the entries. A Bash for loop with a shell variable uses the following syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter \#Define the shell variable variable\="a single item" \#Iterate through the variable and apply the operations for item in \$variable do command1 command2 command3 done \#Define the shell variable variable="a single item" \#Iterate through the variable and apply the operations for item in \$variable do command1 command2 command3 done ``` #Define the shell variable variable="a single item" #Iterate through the variable and apply the operations for item in $variable do command1 command2 command3 done ``` The shell variable only contains one data element, but the Bash loop automatically iterates through space-separated items, treating them as different entities. Consider this example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter var\_numbers\="1 2 3 4 5" for number in \$var\_numbers do echo "Number: \$number" done var\_numbers="1 2 3 4 5" for number in \$var\_numbers do echo "Number: \$number" done ``` var_numbers="1 2 3 4 5" for number in $var_numbers do echo "Number: $number" done ``` Instead of printing the numbers as a string, the bash loop will print them individually because they are separated by a space. To treat the items as a single entity, enclose the **\$var\_numbers** variable in the **for-in** expression with quotation marks, like the following: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for number in "\$var\_numbers" for number in "\$var\_numbers" ``` for number in "$var_numbers" ``` [![The output of a bash for loop with a single-item variable](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2023/09/bash-loop-with-single-item-variable-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2023/09/bash-loop-with-single-item-variable-output.png) You can change the behavior of Bash variables to change the loop output. To learn more about it, check out our [bash variables](https://www.hostinger.com/tutorials/bash-variables) tutorial. ### **How to use a Bash for loop with strings** Combining a Bash for loop with strings enables you to iterate through text for operations like [concatenating](https://www.hostinger.com/tutorials/bash-concatenate-strings), which is typically grouped into a shell variable or array. Using a shell variable is common if your strings are not separated by a space, like the following syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter variable\="string1 string2 string3" for item in \$variable do command1 command2 command3 done variable="string1 string2 string3" for item in \$variable do command1 command2 command3 done ``` variable="string1 string2 string3" for item in $variable do command1 command2 command3 done ``` Meanwhile, use a Bash for loop with strings grouped into an array if your string contains whitespace. In addition to allowing the bash loop to read space-separated items, they are easier to iterate over and expand. Here’s the syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter array\=("First item" "Second item" "Third item" "Fourth item") for item in "\${array\[@\]}" do command1 command2 command3 done array=("First item" "Second item" "Third item" "Fourth item") for item in "\${array\[@\]}" do command1 command2 command3 done ``` array=("First item" "Second item" "Third item" "Fourth item") for item in "${array[@]}" do command1 command2 command3 done ``` ### **How to use a Bash for loop to create a three-expression loop** Using a Bash for loop to create a three-expression loop uses a structure similar to the C programming language. This structure is comprised of three writing expressions – an initializer (**EXP1**), a condition (**EXP2**), and a counting step (**EXP3**). The initializer sets the initial script variable, and the condition determines whether or not the loop continues. Meanwhile, the counting step alters the initial value until it meets the specified condition. The syntax of this loop is as follows: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done ``` for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done ``` For a better understanding, consider the following code example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter \#!/bin/bash for (( c=1; c\<=5; c++ )) do echo "The number \$c" done \#!/bin/bash for (( c=1; c\<=5; c++ )) do echo "The number \$c" done ``` #!/bin/bash for (( c=1; c<=5; c++ )) do echo "The number $c" done ``` The code sets the loop’s initial value as **1**. The loop will run as long as the condition in **EXP2** is true – the code variable shouldn’t be bigger than **5**. The counting expression has the **\++** sign, which increments the initial value by one each time the loop runs. The bash script will echo a message “**\$c**” which refers to the loop value, starting from **1** until it reaches the specified condition. The output will be as follows: [![The three-expression bash for loop output](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/three-expression-bash-loop-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/three-expression-bash-loop-output.png) ### **How to use a Bash for loop to create an infinite loop** Creating an infinity loop using a Bash for loop lets you execute code indefinitely until you terminate the process manually by pressing **Ctrl + C**.There are different ways to do so, such as using the **while** expression: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter while true do echo "Hello, world!" sleep 1 done while true do echo "Hello, world!" sleep 1 done ``` while true do echo "Hello, world!" sleep 1 done ``` When the condition is **true**, the command will print the **Hello, world\!** message with a one-second delay. The snippet uses the **while true** conditional statement to enable the code to always return the successful exit status. Since the condition remains **true**, the code will keep looping the [**echo** command](https://www.hostinger.com/tutorials/echo-command-linux) to print the message. Another method is to use the three-expression infinite loop: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for (( ; ; )) do echo "Hello, world!" sleep 1 done for (( ; ; )) do echo "Hello, world!" sleep 1 done ``` for (( ; ; )) do echo "Hello, world!" sleep 1 done ``` In the snippet, we set all the expressions to empty. Since there’s no termination condition to meet, the loop will continue until the user stops it. [![The infinite bash for loop output](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/infinite-bash-loop-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/infinite-bash-loop-output.png) ### **How to use a Bash for loop to create the skip and continue loop** A Bash for loop lets you create a loop that skips a specific value and continues running afterward. This operation uses the following syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in 1 2 3 4 5 do if \[condition\] then \#Continue with the next iteration of i and skip the statement continue fi statement done for i in 1 2 3 4 5 do if \[condition\] then \#Continue with the next iteration of i and skip the statement continue fi statement done ``` for i in 1 2 3 4 5 do if [condition] then #Continue with the next iteration of i and skip the statement continue fi statement done ``` Here’s a skip-and-continue loop code example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in {1..5} do if \[\[ "\$i" == '4' \]\] then continue fi echo "Hello \$i" done for i in {1..5} do if \[\[ "\$i" == '4' \]\] then continue fi echo "Hello \$i" done ``` for i in {1..5} do if [[ "$i" == '4' ]] then continue fi echo "Hello $i" done ``` In the snippet, we define the items to modify as numbers one to five. We add an **if** condition, stating that when the variable value equals **4**, the loop doesn’t run the code and continues to the next value. It means the loop will operate on **1**, **2**, **3**, and **5**, as the output shows: [![The skip-continue bash loop output](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/skip-continue-bash-loop-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/skip-continue-bash-loop-output.png) ### **How to use a Bash for loop to create a conditional exit with break loop** A Bash for loop lets you create a loop that automatically stops when it meets a specific condition. using the **for-in** construct like this syntax: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for i in 1 2 3 4 5 do if \[condition\] then break fi statement done for i in 1 2 3 4 5 do if \[condition\] then break fi statement done ``` for i in 1 2 3 4 5 do if [condition] then break fi statement done ``` You can add another command at the end of the code, which will run after the loop ends. Consider the following example: Plain text Copy to clipboard Open code in new window EnlighterJS 3 Syntax Highlighter for state in Alabama Alaska Arizona Arkansas California do if \[\[ "\$state" == 'Arkansas' \]\]; then break fi echo "state: \$state" done echo 'That’s all!' for state in Alabama Alaska Arizona Arkansas California do if \[\[ "\$state" == 'Arkansas' \]\]; then break fi echo "state: \$state" done echo 'That’s all!' ``` for state in Alabama Alaska Arizona Arkansas California do if [[ "$state" == 'Arkansas' ]]; then break fi echo "state: $state" done echo 'That’s all!' ``` The loop script prints all state names specified in the list but stops once the break condition is met, namely when the current value equals **Arkansas**. Then, it moves to the next instruction to echo the **That’s all\!** message. Here’s what the output looks like: [![The output of bash loop with break conditional exit](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/bash-loop-break-condition-output.png/public)](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2019/02/bash-loop-break-condition-output.png) ### **How to effectively use a Bash script in Hostinger VPS** Using a Bash for loop with your web hosting provider’s features can further simplify your server administration tasks, making it more efficient. For example, Hostinger VPS plans have a **browser terminal** built into our hosting custom control panel, hPanel. It lets you run Linux commands and utilities like bash loop directly from your web browser. [![](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2023/02/VPS-hosting-banner.png/public)](https://www.hostinger.com/vps-hosting) We have an AI agent, **Kodee**, that simplifies VPS management for beginners. For example, you can ask it to generate Bash for loop scripts for various tasks using simple prompts like “Can you generate a Bash for loop that restarts a list of services?” or “Please create a Bash for loop to back up multiple directories.” ![Kodee generates a bash for loop script based on a user request](https://imagedelivery.net/LqiWLm-3MGbYHtFuUbcBtA/wp-content/uploads/sites/2/2019/02/kodee-generates-a-bash-for-loop-script.png/public) To access the tool, log in to hPanel and click on **VPS** in the top menu. Select the applicable server and navigate to **Kodee** in the sidebar. To get accurate results, ensure your [web development AI prompts](https://www.hostinger.com/tutorials/ai-prompts-for-web-developers) are specific and clear. Check out our [AI prompts for VPS management](https://www.hostinger.com/tutorials/ai-prompts-for-vps-management) guide to learn more about using **Kodee** for various tasks. **Important\!** Due to AI limitations, some answers may be inaccurate or obsolete. ## Key takeaways A Bash for loop is great for automating repetitive tasks, processing data, and managing a UNIX-like system. For example, with a single execution, you can iterate through names to automatically create new users when [setting up a new VPS](https://www.hostinger.com/tutorials/how-to-set-up-vps). As explained, you can perform various assignments with a Bash for loop by combining it with other Bash constructs, like **for-in**. You can further expand its functionality by incorporating other command-line tools to create an efficient way to complete a task. Now that you understand the basics of a Bash for loop, it’s time to practice using it in day-to-day tasks.
