On your systems without Ummm... are you saying that I have a Cygwin mount table outside of Cygwin? > Cygwin installed you could just mount /bin to point to a directory that > contains sh.exe and it would work. Though I don't recommend that. If Yeah - I thought of that. But then I have to call mount, but not from inside the running program (since, obviously, that won't work for the same reason). I'll try running it from a batch file on a non-Cygwin machine.

I read on the Cygwin page that this group was the catch-all for all sorts of Cygwin-related problems, other than the ones specifically covered by the other lists. Clearly, this is Cygwin-related. I thought I was in the right place. Apologies for the intrusion - I'm just looking for answers to my Cygwin problem. -- Archie -- Archie Warnock Internet: warnock@awcubed.com -- A/WWW Enterprises http://www.awcubed.com -- As a matter of fact, I _do_ speak for my employer. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
