Broadcast a Command with SSH

Use ssh to broadcast a command to a list of hosts given that you've already setup ssh keys and the login is automatic.

#!/bin/bash
#
# This is a sample script to "broadcast" a command via ssh to a set of computers
# each server to distribute to
DHOSTS="host1 host2 host3";
 
# Loop through each server and distributes each file
for DHOST in $DHOSTS; do
	echo "Working on host $DHOST with command $1";
	ssh $DHOST $1;
done
