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?
I have looked at the alternatives command but that seems just a tad involved. And since this is a production server I am not quite ready to trust to RVM either.
In the short term I have simply removed the CentOS version which has resolved the immediate issue. However, I would like to know how to handle this a little more elegantly in future.
