Re: RFS: c3-tool-suite - Cluster Command & Control tool suite
Just out of curiosity what is the advantage of c3 over dsh? Asside from
the command names (alias) being longer and the potential for cpush to be
multicast (which it appears not to be), I don't see any advantages. I'm
not trying to discourage you from packaging/sponsoring/installing/using
it, this is just for my own information.

Okay, this isn't trivial to do with dsh, but possible if ssh works
cluster-wide without password:
dsh -cgcluster "scp $FILE $(hostname -f):$FILE-\$(hostname)"
Where the first hostname is executed locally and the second on the node.

roughly the same
