grep/dired

[Mike Ballard]

Hi - 

Tried looking around but sort of don't know how to search for the answer -
when I open a dired buffer of other than ~/, then use M-x grep, it
searches files in ~/.  I'm pretty sure the reason is because in ~/.cshrc
the last thing I do is 'chdir $HOME' (which I don't want to change).  In
csh you can start a script with "-f" telling it to use current env - is
there a way to do the same thing for Emacs' grep so that it will grep on
the current dired buffer?  If possible I'd like to use grep and not
find-grep-dired.

Then change your .cshrc to do that chdir only in interactive sessions.

In general, a shell startup file should take great care not to do
anything fancy, like stty etc., in non-interactive sessions; otherwise
you will see strange bugs in Emacs commands that invoke subsidiary
programs.

Yes, you do.  :-)

You could try this hack: (setq shell-command-switch "-f -c")

Alright, 2-0.  I changed ~/.cshrc.  Evidently two problems have now been
fixed :-)

Thanks both...
