    When executed “mkpasswd” command with -l option, I get below error.

    $ mkpasswd -l 20
    mkpasswd: invalid option -- 'l'
    Try 'mkpasswd --help' for more information.

    Without -l option it works.

    $ mkpasswd 20

      Thanks for sharing the tip, it seems you’re tried these instructions on Ubuntu based distro, so seems some difference options and arguments replaced or changed in the latest version of mkpasswd package..
