INSTALL

Use cpanminus(1) command:

    cpanm App::optex::pingu

PINGU ALIAS

You can set shell alias pingu to call ping(1) command through optex.

    alias pingu='optex -Mpingu --pingu ping'

However, there is more sophisticated way to use optex alias function. Next command will make symbolic link pingu->optex in ~/.optex.d/bin directory:

    $ optex --ln pingu

Executing this symbolic link, optex will call system installed pingu command. So make an alias in ~/.optex.d/config.toml to call ping(1) command instead:

    [alias]
        pingu = "ping -Mpingu --pingu"

MAKING NEW PING OPTION

You can add, say, --with-pingu option to the original ping(1) command. Make a symbolic link ping->optex in ~/.optex.d/bin directory:

    $ optex --ln ping

And create an rc file ~/.optex.d/ping.rc for ping:

    option --with-pingu -Mpingu --pingu

Then pingu will show up when you use --with-pingu option to execute ping(1) command:

    $ ping --with-pingu localhost -c15

If you want to enable this option always (really?), put next line in your ~/.optex.d/ping.rc:

    option default --with-pingu
