DiSh - A poor man's distributed shell
SYNOPSIS
DiSh is a very basic implementation of a distributed shell system. A distributed shell lets you run the same command on multiple remote machines, either incrementally or in parallel. This implementation uses SSH to access each machine, so it is recommended that you have SSH keys setup to allow a passwordless login so you can avoid all the redundant typing.

STATUS
