So this reminds me of an oft-forgotten point in portability of shell 
scripts: the popularity of the linuxism #!/bin/bash (though it appears 
it has crept into Mac OS X as well, sad...).

Whether it's writing a script that doesn't actually need bash (just 
/bin/sh would do) or doing the simple #!/usr/bin/env bash (something I 
got one of my upstreams to do to better support OpenBSD: 
), these little portability tricks go a long way to ease transfer 
between machines.

Maybe a POSIX shell meeting is in order (targeting POSIX shell, only 
using command flags that are included in the POSIX base, etc.) - would 
you be up to doing such a meeting?

We could even do a shell script swap meeting: bring your favorite 
scripts and share.
Or a shell script porting meeting: actually making sure your scripts 
work on all the different platforms in the world.
