Passing Ruby interpreter arguments with hashbang command

问题

I am using the following hashbang command with my RVM installation. How do I pass the -w argument to the ruby interpreter?

#!/usr/bin/env ruby

Thanks.

回答1:

I recommend setting the RUBYOPT environment variable. In this manner, you don't have to edit your executables.

RUBYOPT="-w $RUBYOPT"

回答2:

According to this reference you can use a separate declaration outside of the shebang for that:

#! /usr/bin/env ruby
$VERBOSE=true
