password-free ssh and writing executable bash scripts

First, a tangentially related note on password-free ssh and writing executable bash scripts.  By example… I wanted to quickly login to the login node for the research computing cluster at Rice University (all names/addresses have been changed).  Here’s how one would have to login the hard way:

Matty@HomeComp~$ ssh Matty@Cluster.rice.edu

then you’d have to enter your password. Here’s how to skip the step of entering your password every time [link].

After I set up pwd-free ssh, I wrote the following bash script:

#! bin/bash
# filename: sshCluster
# script to login to Matty@cluster.rice.edu automatically
ssh Matty@cluster.rice.edu

Then at the command line:

~/$ chmod +x sshCluster

Then you should be able to simply type

~/$ sshCluster

at the command line to login.
