In this post, we will take a quick look at the cp command in Linux, and examine how it can be used in different scenarios. ## **How to Copy Files in Linux CLI** Copying files is one of the simplest actions that you can perform on a computer. To copy files via the command line you can use the cp command, which stands for ‘copy’. The general syntax for the cp command is: ``` cp [OPTIONS] SOURCE(s)... DESTINATIONCopy ``` The `SOURCE(s)` can be **one or more files or directories**, and the `DESTINATION` can be a single file or directory. If you’ve passed more than two parameters to the command, then the last one is always considered the destination, and all other parameters before it are considered the source(s). - If the `DESTINATION` is a directory, the `SOURCE` **files or directories** are copied into it. - If the `DESTINATION` is a file, the `SOURCE` **file** is copied and renamed as the `DESTINATION` file. Here is a simple example of how to copy a file named `file.txt` from the current directory to another directory named backup: ``` cp file.txt backup/Copy ``` This will copy the file `file.txt` to the `backup` directory with the same name. If you want to copy the file with a different name, you can specify the new name after the backup directory: ``` cp file.txt backup/new_file.txtCopy ``` This will copy the file `file.txt` to the backup directory as `new_file.txt`. ## **How to Overwrite Existing Files** By default, `cp` will overwrite any existing files in the destination without asking for confirmation. However, this behavior can be changed by using different flags or options with the `cp` command. Here are some of the common flags that can affect how `cp` handles overwriting: - **`-f` or `--force`**: This option will force cp to **overwrite any existing files** in the destination, even if they cannot be opened or removed. This option will also ignore any `-n` option that is used before it. For example, `cp -f source.txt destination.txt` will overwrite *destination.txt* with *source.txt*, regardless of any permissions or errors. - **`-i` or `--interactive`**: This option will make cp **prompt the user** before overwriting any existing files in the destination. You can choose to overwrite or skip the file by typing `y` or `n` and then pressing Enter. If you’re copying multiple files at once, you will be prompted for each file separately. If you don’t type anything and press Enter then the file will not be overwritten. This option will also override any `-n` option that is used before it. For example, `cp -i source.txt destination.txt` will ask the user if they want to overwrite *destination.txt* with *source.txt*, and proceed accordingly. - **`-n` or `--no-clobber`**: This option will **prevent cp from overwriting** any existing files in the destination. If the destination file already exists, cp will skip it and move on to the next file. This option will also override any `-i` option that is used before it. For example, `cp -n source.txt destination.txt` will **not** overwrite *destination.txt* with *source.txt*, if *destination.txt* already exists. - **`-u` or `--update`**: This option will make cp **copy only when the source file is newer** than the destination file, or when the destination file does not exist. This can be useful for updating or synchronizing files between different locations. For example, `cp -u source.txt destination.txt` will overwrite *destination.txt* with *source.txt*, only if *source.txt* is newer or *destination.txt* does not exist. Note that these flags can be combined to achieve different effects. For example, `cp -uf source.txt destination.txt` will force cp to overwrite *destination.txt* with *source.txt*, only if *source.txt* is newer or *destination.txt* does not exist. ## **Changing the Default Behavior** On some computers, the default behavior of the cp command can be affected by an **alias**. An alias is a way of creating a shortcut or a new name for a command, with some predefined options. For example, some Linux distributions come with the following alias pre-defined in their code: ``` alias cp='cp -i'Copy ``` This means that whenever the user types `cp`, the shell will actually run `cp -i`, which will prompt the user before overwriting any files. ### **Checking For An Existing Alias** If you’re not sure whether your computer has a predefined alias, then you can run the following command to list all aliases, and then look to see whether the cp is present in the output: ``` aliasCopy ```  ### **Removing An Alias** To remove the alias for `cp`, you can run the command `unalias cp`, which will restore the default behavior of `cp`.  In the above example, we can see that an alias was defined for the `cp` command. After executing the `unalias` command, the alias entry was removed from the list. ### **Temporarily Bypass An Alias** If you don’t want to permanently remove the alias, you have an option to use a backslash before the cp command to bypass the alias and run the original command. For example, `\cp source.txt destination.txt` will overwrite *destination.txt* with *source.txt*, without prompting the user.  In the above example, we can see that the user was prompted for input when executing the copy operation, but not when the command was prefixed with the \\ character. ### **Automatically Accepting All Prompts** In Linux there are multiple ways to do the same thing using different methods. If you don’t want to use the in-built `-f` option to overwrite files then you can use the **copy** command in conjunction with the **yes** command to automatically respond with y to all prompts. ``` yes | cp -v source destinationCopy ```  In the above example, we can see that the copy command prompted us for input before replacing each file, but the yes command responded ‘yes’ to each and every single one of them nearly instantaneously. ## **Wrapping Up** In this article, we have discussed how to copy files and directories in Linux via the command line. We have also explained different options and features of the copy command that are helpful in day-to-day usage. If you’re learning Linux to better manage your servers, we wish you all the best!
