# NAME

pingu - optex make-everything-pingu filter

# SYNOPSIS

**optex** -Mpingu --pingu _command_

# DESCRIPTION

This **optex** module is greatly inspired by [pingu(1)](http://man.he.net/man1/pingu) command and
make every command pingu not only [ping(1)](http://man.he.net/man1/ping).  As for original
command, see ["SEE ALSO"](#see-also) section.  All honor for this idea should go
to the original author.

features.

for detail.

# INSTALL

Use [cpanminus(1)](http://man.he.net/man1/cpanminus) command:

    cpanm App::optex::pingu

# PINGU ALIAS

You can set shell alias **pingu** to call [ping(1)](http://man.he.net/man1/ping) 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-&gt;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)](http://man.he.net/man1/ping) command instead:

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

# MAKING NEW PING OPTION

You can add, say, **--with-pingu** option to the original [ping(1)](http://man.he.net/man1/ping)
command.  Make a symbolic link `ping-&gt;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)](http://man.he.net/man1/ping) 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
