Coloring is done by [Term::ANSIColor::Concise](https://metacpan.org/pod/Term%3A%3AANSIColor%3A%3AConcise) module. See its
document 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->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"
# MAKING NEW PING OPTION
You can add, say, **--pingu** option to the original [ping(1)](http://man.he.net/man1/ping)
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 --pingu -Mpingu
Then pingu will show up when you use **--pingu** option to execute
[ping(1)](http://man.he.net/man1/ping) command:
$ ping --pingu localhost -c15
If you want to enable this option always (really?), put next line in
your `~/.optex.d/ping.rc`:
option default --pingu
