Please forgive my ignorance but I need a explanation of how to accomplish the following since I cannot figure it out from the documents.

I have a Ruby script with a shebang line that looks like this:

#!/usr/bin/env ruby

On one particular host I have two Ruby interpreters installed; one the CentOS base version 1.8.6 in /usr/bin/ruby the other version 1.8.7 in /usr/local/bin/ruby. In my shell the which command finds /usr/local/bin/ruby. In a cron job the /usr/bin/ruby is used by the /bin/env invocation.

My question is: How does one configure /bin/env to return the /usr/local/bin/ruby version? or does that question even make sense?

Why not just change the shebang line to use

#!/usr/local/bin/ruby
