    Description:
        Used to run a program that interacts with a file/directory (i.e: 'nano', 'rm', 'mkdir', 'git', etc).
        If you don't have sufficient permissions for the file/directory you're trying to access, '$NAME' will
        automatically re-run the program with 'sudo'.

    Examples:
        $NAME nano /etc/ssh/sshd_config
        $NAME rm /usr/local/bin/something

    $NAME v$VERSION
