Parallel SSH execution and a single shell to control them all

Posted by: Anonymous [ip: 87.230.108.21] on November 06, 2008 10:08 AM
What I'm curious about is this:
"""
if you want to interactively edit the same file on multiple machines, it might be quicker to use a parallel SSH utility and edit the file on all nodes with vi rather than concoct a script to do the same edit.
"""

I would have found a short note on which of these three is capable of doing so very helpfull. Cluster SSH's description sounds as though it would be the tool that could do it. But I just don't have the time to test it just yet.
Anyone tried that yet? Or knows to which tool this statement refers to?
