Yeah, you can just use “ruby script.rb”.execute() to execute anything available on the PATH.

Hey, nice post!
Could you please suggest if we can call a ruby script from a groovy script?
thanks!

well, i was playing around with a groovy shell script. i’m sure you’ll agree, it’s pretty sophisticated:

#!/bin/env groovy
println “hey”

my computer has a core 2 duo u9400 1.4 ghz cpu, 1 gb ram, win xp sp3, java 1.6.0_13, and groovy 1.6.3.

when i call it directly from the bash prompt it takes 10 seconds to run. when i call it as an argument to groovy.bat, it takes 7 seconds.

on the other hand, ruby ran it in less than 1 second and jruby ran it in 5 seconds.

groovy’s 7-10 seconds performance is very slow and a big turn off compared to using other dynamic languages. my sense is that groovy’s start time is the problem.

does anyone have ideas on how to make groovy run shell scripts faster?

Yes the XML handling is superb in Groovy :)

Nice write-up Eric.

This is much more appealing that using awk and bash.
