I needed to create a bash shell script tonight that called another shell script with options that then would load a Ruby environment and execute certain commands within a Ruby project. I ran into numerous issues but most were silly things such as typos or other minor issues caused by myself. The one issue I had a little trouble figuring out because of the file that was causing the error related to cron not being able to run “/usr/bin/env: ruby”. My bash script worked perfectly from the Linux CLI shell however when attempting to run it I would always get the same error. Below I list details about the error, where I finally located what the error was, and how to resolve the error.
