Hi Prashanth,
The VM that you are using does not include the necessary plugin support for OSProcess. There are some newer VMs that do have this support, for example this one:
http://www.mirandabanda.org/files/Cog/VM/VM.r2499/cogwin.zip
But this will not work with Squeak 3.8.
Since you are using a Squeak 3.8 image on Windows, I suggest that you try using the Process Wrapper package instead of OSProcess. This is a package written by Levente Uzonyi that should do exactly what you need. You can find it on SqueakSource:
http://www.squeaksource.com/ProcessWrapper

If this does not work for you, please write again and I will try to find an OSProcess plugin for Windows for you.

Dave,
- 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,

Dave, Thanks for the pointer. Somehow, I missed the VM part. I will investigate. I am on the road today whole day. Will try this tomorrow (Wednesday ) and report back.

Hi,
I am trying to trigger a ruby script from within Squeak. I loaded
OSProcess

OSProcess correctly.
I am using a 3.8 stable version.
Hello Prashanth,
You can find some general information here: http://wiki.squeak.org/squeak/708
OSProcess requires a special plugin for the VM. If OSProcess is not working, it is possible that the VM you are running does not contain this support. Can you say what operating system you are using, and if possible what VM?
I will mention also that if you want to interact with a ruby script from Squeak through pipes (in other words, read and write the standard input and output streams from the ruby program), then you will also want to load package CommandShell and use the class PipeableOSProcess.
