Run a command on all nodes

This will run the cat command on all nodes and output the results on the head node and redirect the output to a file. This gives a list of hostnames and MAC addresses in a txt file.

[root@HOST~]#cluster-fork cat /etc/sysconfig/network-scripts/ifcfg-eth0:0 | egrep "compute|HWADDR" > HostHWaddr.txt
