| Boilerpipe Text | Do you know how to copy a file in Linux? Copying files and directories in Linux is one of the most basic (but essential) Linux commands. And it can be a little more complex than you may think. When you copy a folder, text file, or another type of file to a destination directory, you may be copying it locally (on your own drive) or to another location (uploading it to a network drive).Â
On Linux, commands are based on whether you have permissions and access, so you need to understand the basics of permissions and access to copy files and directories.
Why should you use Linux?
Once you know the right commands, you’ll find that a lot of things are easier. Today, we’re going to take a look at how to copy a file in Linux.
First, let’s copy a file or folder in Linux from a source directory to a destination directory. We will use the CP command to copy the file.
The syntax for the CP command is:
cp source_file destination_fileÂ
In this example, we are copying the file “source_file” to the destination directory “destination_file.” Keep in mind that this is the entire directory path. So, we could be doing something like this:
cp backup.txt /backups/archives/backup/backup2.txtÂ
That’s not great naming etiquette. But it highlights the point that we are not just copying between files but also between directory paths.
The CP command in Linux copies the contents of the source file into the destination file. It’s the fastest, easiest way to copy a file directly from the command line.
How to copy multiple files in Linux using the CP command
If you want to copy multiple files at once, you can use the CP command with a wild card.
For example, if we wanted to copy the files “source_file” and “source_file2” to the destination directory “destination_file,” we would use the command:Â
mv source_file* destination_fileÂ
This command will copy both files and place them in the destination directory. But we need to be careful. For instance, if we did “s*”, we would be copying all the files that started with the letter “s.” That could be hundreds or even thousands of files in the wrong directory.
Linux makes it easy to do things you want to do — if you’re careful. But if you’re not vigilant, you can also easily make major mistakes.
How to copy a folder with the CP command
Copying a folder can be a little more complex than copying a file. Make sure you have the correct permissions and that the folder structure is maintained.Â
To copy a folder in Linux, use the CP command with the -r switch. This switch tells cp to copy the folder and all of its contents, including subdirectories.
The syntax for the cp -r command is:Â
cp -r source_directory destination_directoryÂ
In this example, we are copying the folder “source_directory” to the destination directory “destination_directory.”Â
When you use the CP command with the -r switch to copy a folder, the contents of the source folder will be copied into the destination folder, including all subdirectories.Â
It’s important to note that Linux really treats folders the same as files. In many aspects, a folder is a file; it’s a file that contains a list of other documents. That’s why most of the command line functions that work on files will also work on folders, and the opposite is also true.
How to use RSYNC to copy files in Linux
If you want to copy files or directories between two locations, you can use the rsync command. You will need to first install RSYNC with the following command:
sudo apt-get rsync
Once RSYNC has been installed, you’ll use it with the following command syntax:
rsync source_file destination_fileÂ
In this example, we are copying the file “source_file” to the destination directory “destination_file.”Â
The rsync command in Linux copies files or directories between two locations, but it also synchronizes them. This means that it compares the files in the two directories and only copies the files that are different. This can be really helpful when you are copying a lot of files because it can dramatically reduce the amount of time it takes to copy them.
Today, we would generally use an FTP or SFTP program to do this. But RSYNC is an easy-to-use and lightweight replacement.
The rsync command can also be used to copy files or directories between two Linux servers. If you’re connecting to another network device or a server through the internet, you will need to know your host information, host login name, and host password. These can be included in the RSYNC command line.
How to use the MV command in Linux
The MV command in Linux is used to move files and directories. The syntax for the MV command is the same as CP:
mv source_file destination_fileÂ
In this example, we are copying the file “source_file” to the destination directory “destination_file.”
The CP command copies the source file’s contents into the destination file. The MV command moves (or renames) the source file to the destination file.Â
If the destination file already exists, the MV command will overwrite it without asking for confirmation. The CP command will not overwrite an existing destination file.Â
Managing files and permissions in Linux
As noted, you need the right
Linux permissions
to copy a file in Linux. The same is true for copying a folder.Â
The permissions for a file or folder are controlled by the user, group, and world. There are three types of permissions: read, write, and execute.Â
The read permission allows you to view the contents of a file. The write permission lets you to make changes to the file. The execute permission permits you to run the file as a program.Â
If you can’t read a file, then you can’t copy it. If you can’t write to the drive that you want to write to, you won’t be able to copy it. So, you need to make sure that your permissions have been appropriately set before you start to move, copy, and otherwise manipulate files.
Note that you can usually run commands “as an administrator” if you find that you don’t have the right permissions (provided that you are an administrator). This only requires that you say “
Sudo
” before you run your command.
In the case of copying files, you would write:
sudo cp source_file destination_file
This would run the above command line function as an administrator. Administrators, by default, have read, write, and execute permissions on all files and folders.
Key takeaway: If you find yourself running into problems when copying, renaming or moving files, it’s likely to be a permissions issue.

First, let’s copy a file or folder in Linux from a source directory to a destination directory. We will use the CP command to copy the file.
The syntax for the CP command is:
| |

| cp source\_file destination\_file |
In this example, we are copying the file “source\_file” to the destination directory “destination\_file.” Keep in mind that this is the entire directory path. So, we could be doing something like this:
