You may need to write a bash shell script that accesses data stored alongside the script, while your current working directory might be elsewhere. In my case the shell script needed to use Node.js scripts stored next to the shell scripts -- the shell script acting to simplify running the Node.js scripts. The "data" to be accessed in this case is the Node.js scripts, plus the support modules required to run them. You may have other data like a list of hostnames or who-knows-what.
