RE: invoking process under emacs

[Manish Khettry]

Thanks for the help. I found that unsetting the SHELL environment variable before starting emacs
and editing the Windows registry did the trick.

cheers,
Manish

Since you have bash (I assume it is Cygwin's), I'm almost sure you have
grep too. I think the problem lies elsewhere. I think that what Cygwin
calls /bin is in windows terms something like c:\cygwin\bin.

My solution (and I use it almost everyday) is:
  1) Have the "c\cygwin\bin" (or whatever is the exact dir in your case)
     in the windows path BEFORE you start NTemacs.
  2) Set the SHELL value for emacs to "bash" (NOT "/bin/bash")
     This is done in the registry:
       [HKEY_LOCAL_MACHINE\SOFTWARE\GNU\Emacs]
       "SHELL"="/bin/bash"

You may also want to have the Cygwin mounts for you NTemacs editing,
There is a package cygwin-mount.el maintained by Klaus Berndl (the last
version is from 2001-05-18) it may be found in the Cygwin mail archive:
