Subject: [ruby-talk:13033] How do I properly munge stdout and stderr when using IO.popen?

Or alternatively is there a better way to do this?

When I do a:

pipe = IO.popen( "/usr/atria/bin/cleartool", "r+" )

# There's no such file as blah/blah so cleartool will output
# that message on stderr.
pipe.puts( "ls blah/blah\n" )

# So the error message goes to the screen and the pipe.gets hangs.
line = pipe.gets

I'd prefer the ability to munge stdout and stderr what is the proper
way( so I can interpret the result properly )?

Thanks!
