Hello Prashanth,

You can find some general information here:

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.
