Running command line scripts from Rails...

Hi

I have an application that makes use of some tools that are provided on the installed system. (statistical model compilation).

How should I do this gracefully w/ Rails.

In the past (Java equivalent) I have relied on either an API being provided OR scraping the results of System.exec (I guess the Ruby equivalent is Runtime.exec)... not sure how to do this in Rails though.

Thanks for any help.

There are two ways I know of. To run a simple command like ls -l:

system 'ls -l'

%x{ls -l}

There are subtle differences between the two, but see which works for you.

Thanks I'll do some reading on it this weekend and post some results.

Appreciate the reply.
