In Linux, what does the command 'mv' do?

The command 'mv' in Linux is used primarily for moving or renaming files. When you use this command, you can specify a source file or directory and a destination, and it will transfer the specified items to the destination location. If the destination is the same filesystem and you are providing a different name, 'mv' also serves to rename the file or directory.

For example, if you have a file named "file1.txt" and you want to rename it to "file2.txt", the command would be mv file1.txt file2.txt. Additionally, if you want to move "file1.txt" from your current directory to a directory called "Documents", you would use mv file1.txt Documents/.

The other options do not accurately describe the function of 'mv'. While one option mentions removal, that function is actually served by the 'rm' command. Creating directories is done using the 'mkdir' command, and copying files is achieved with the 'cp' command. Therefore, the ability of 'mv' to either move files to a different location or to rename them clearly highlights its role in file management within a Linux environment.
