Question

In the Bash shell, I would like to run a directory of ruby scripts from anywhere. Adding the directory to the $PATH doesn’t do it.

I want to type ‘ruby,’ start typing the first letters of a script name, and then press tab to autocomplete the script name.

For instance, I’m in /~/username/foo/bar and want to run /~/ruby/test/script1.rb

~/username/foo/bar $ ruby scri

press tab and

/username/foo/bar $ ruby script1.rb

appears. And then I’d be able to press enter and have the script run, even though I’m not in the right directory.

Is this possible?

Answer 1

If you add this to the top line of you scripts. Use ‘which ruby’ to find out where your interpreter is located and use that path instead.

#!/usr/local/bin/ruby -w

Then change them to be executable with

chmod +x ruby_script.rb

You’ll be able to ruby them like any normal program, for example (although you may want to lose the .rb extension)

ruby_script.rb
