The mv command is a utility that allows you to move or rename files and directories on a Unix or Linux system.
To use the mv command, you can type mv followed by the source file or directory and the destination file or directory.
For example, to move the file file.txt from the current directory to the /tmp directory, you can use the following command:
mv file.txt /tmp
This will move the file file.txt from the current directory to the /tmp directory.
To rename a file or directory, you can use the mv command by specifying the same source and destination, but with a different name.
For example, to rename the file file.txt to newfile.txt, you can use the following command:
mv file.txt newfile.txt
This will rename the file file.txt to newfile.txt in the current directory.
The mv command also has several options that allow you to customize the behavior of the command. For example, you can use the -f option to force the move or rename operation, or the -i option to prompt for confirmation before overwriting an existing file or directory.
For more information about the mv command and its options, you can consult the documentation for your specific Unix or Linux system.
