Ping(1M) on OpenSolaris Easter Egg

It's amazing what you discover whilst working a weekend shift with a bit of time to spare. Whilst perusing through the shell scripts used as part of the Sun in-house built VPN solution (Oracle are giving it the chop in favour of Cisco SSL AnyConnect client which doesn't officially work on Solaris x86 - it does with the help of openconnect though ;-) ), I discovered a little easter egg in ping(1M).

Fire up a terminal and ping a host:

$ ping     is alive

Nothing fancy there and exactly as I expected. However, if you're a Linux/Mac user, this is NOT what you were expecting. So lets make the Linux/Mac users happy with our new little easter egg...

$ ping

Now that looks familiar to Linux/Mac users and Solaris users will recognise this as the output you get when using the -s flag.

So, whilst not really anything amazing, this little undocumented environment variable allows you to get the output Linux/Mac users are used to without the need for setting up an alias of continually remembering to add the -s flag.

I've only tested this on OpenSolaris so your experience may vary.
