I decided to go with this gsh:
I looked at pdsh, and it looks powerful, but more complicated, too. This
gsh does everything I need, and has a simple config file syntax as well
as exactly the command sytnax I was looking for. I already have it
completely configured for my environment. And due to the simpler syntax,
it will be easier to get my coworkers to use it, too. ;)
Thanks for all your replies. Those of you who voted for pdsh, don't
worry, you're votes weren't wasted I still plan to tinker with pdsh.
