Thanks for your reply.

If you ever do get round to completing the implementation of OS pipes for
Windows and you are looking for someone to test it, please keep me in mind.

Best Wishes

Hi Keith,

Unfortunately I never completed the implementation of OS pipes for Windows,
so there is no direct way to feed the output of an ExternalWindowsOSProcess
back into Squeak.

On a unix system, you can do "$ who | edit" in a CommandShell to pipe the
output of the external "who" command (/usr/bin/who) into Squeak. But this
won't work on Windows due to the current lack of OS pipe support.

Me too, Squeak and OSProcess are things I do just for fun. I've put most of
my effort into unix/linux because I find it more entertaining. But Windows
has gotten a lot better in recent years so maybe I should try it again.
