Terminal hack to make logging into a cluster easier

I’ve been looking for a way to make it simpler to quickly login to all nodes of a cluster from a mac terminal. Discovered a small npm module that helped me do it called ttab. With this npm module I can then write a bash script:

rs6 () {
ttab -w ssh bryan@example1.com
ttab ssh bryan@example2.com
ttab ssh bryan@example3.com
ttab ssh bryan@example4.com
ttab ssh bryan@example5.com
ttab ssh bryan@example6.com
if [ “rs6” = $TYPE ]

This will open one new terminal window with 6 tabs all logged into the different servers.
