Re: sh

[Bob McGowan <rmcgowan at veritas dot com>]

Turns out the problem on my end is how I was trying to invoke the shell, using a full path in a shortcut.  When I put it in a batch file and changed it to the format used
in cygwin.bat, it works.

So the process is to copy sh.exe to -sh.exe and then start it with a batch file as follows:

   @echo off
   rem use drive letter where Cygwin is installed.
   c:
   cd \cygwin\bin
   -sh

If doing this, be sure /etc/profile (and any other profiles you set up) do not contain any bash'isms or that the bash stuff is isolated.  I've found that a good way to test
(for bash or ksh) is to do a test of the RANDOM variable.  In standard (sh) shells it will be empty.
