mass

mass.pl is the implementation of a relatively simple idea. Instead of interactively doing some task on one machine, then duplicating the effort on N other machines, write a shell script, then scp it to N machines and execute it as root.

Example

(sic@foo)($:~/mass)- ./mass.pl --name 'solaris' --script pushsomething --su --sshpass
sudo password:
ssh password:

trying to run pushsomething on 1 machines

Here are some key features of "mass":

new: arbitrary expressions to compose hosts out of named sets (union, simple difference, symmetric difference, and intersection)
send files to the remote hosts (RPMs or other packages for example)
retrieve files from them (the contents of /etc for example).
can become root via the following methods:
·ssh login as root
·su
·sudo
·it also supports not becoming root when it's not necessary
uses ssh 1 or ssh 2 or any other ssh options
named lists of machines which can be comprised of arbitrarily complex perl expressions
few dependencies on the remote machines, should work on most unix like OSes.
