How to change / usr / bin / env?

Question

I have scripts that use #!/usr/bin/env ruby, but I switched to using Ruby Enterprise Edition instead of the default ruby, which is included in the Ubuntu server. This way the scripts get confused when I try to run them. How to add Ruby EE path to /usr/bin/env?

Answer 1

#!/usr/bin/env rubysimilar to a simple rubycommand line call , so the same rules apply.

So make sure that rubyfor Ruby EE it is earlier in search order than your other rubys.
