Hey folks,
I stumbled upon this while looking for something else

And it is something I could actually really make use of. But right on that site they list 3 different ones, and so I'm wondering what all is out there and what I should use.
In (HPC) clustering pdsh is very popular. It's available in .tgz with spec-file and rebuilds nicely on c5 with rpmbuild -tb ...

A few examples of what pdsh can do: - pick hosts with compact expressions: -w n[3-10,44] - settable fanout (run on X hosts in parallel) - remote command timeout - pdcp command that allows the copying of file - nifty post-processor that compats output:
$ pdsh -w n[1-3],n5 uname -r | dshbak -c ---------------- n[1-3,5] ---------------- 2.6.18-164.11.1.el5

Is there one that is part of the standard CentOS?
thanks, -Alan
