[Newbies] Re: OSProcess example

[Prashanth Hebbar]

Dave,


   1. I installed CommandShell and could get working the following commands:
   'inspect', 'edit', 'pwd', etc but nothing beyond it.
   2. 'ruby twt-auth.rb'  inside Squeak Shell throws up an error saying:
   'cannot access system to run...
   3. "(PipeableOSProcess command: 'echo test') output" throws up  a DNU on
   ExternalWindowsProcess class >> defaultShellPath


I am trying to trigger a ruby script which posts to twitter.

My environment:

OS: Windows 7
Squeak version: 3.8
Squeak VM version: 3.7.1 (compiled using gcc)
(also tried it on the latest VM 4.1.1)

I will continue to investigate. Any pointers on what I am doing wrong will
help me.

Thanks in advance.

Regards,
