I'm sure that MSYS (from the MingW project, I think) is a useful
piece of software to have.  It contains grep, AFAIK.

Try http://www.gnu.org/software/grep/grep.html

and http://www.gnu.org/directory/grep.html

This guy has done a extremely good job, compiling most of the basic
unix utilities to Windows NT (NT4, Windows 2000, Windows XP):

No dlls needed, it just works!

grep

[Fred Stanke]

I have emacs installed at
C:\Applications\Emacs\bin\runemacs.exe
It uses, *I believe*
c:/Users/Fred/AppData/Roaming/.emacs.d/init.el

when I try to do a grep, I get this error:

-*- mode: grep; default-directory: "c:/Users/Fred/" -*-
Grep started at Wed Mar  8 19:46:54

grep -n the *.txt NUL
'grep' is not recognized as an internal or external command,
operable program or batch file.

Grep exited abnormally with code 1 at Wed Mar  8 19:46:54

What do I need to do to get grep to work.
(FYI: I  have deleted at least one Cygwin installation I had tried.)

Just for mentioning another option if you need it:
Use M-x eshell which has a built-in grep facility.

To reassure yourself, run: 

C-x C-f ~/.emacs.d/init.el

If it opens your config file, you're good. If not, you should move your config into that location.

It looks like the command grep is not in your path. 

To ensure that it is, open the terminal where you usually run grep from and type: 

which grep 

Note the path (if grep is installed).

Then in Emacs: 

M-x eshell RET
which grep RET
echo $PATH RET

Check if grep is found in Eshell's path. If it isn't, you should add it.

Hope it helps

Man, it actually looks like that?

Things sure have changed in my
cyberspace downtime!

What about M-x shell RET and then plain /bin/grep ?

Re: grep

Emanuel, are you talking to me...?

The OP's problem might be caused by a incorrectly configured PATH,
which I can't help because I'm not familiar with Windows/Emacs.
However anyway EShell grep should work by default.

For those who may need to know:
In EShell if you just use "grep" in the command line, it invokes
built-in grep facility implemented by emacs lisp.

And if you want to use system grep, you need to specify it by a leading
star like "*grep".

See below eshell log:
~ $ which grep 
eshell/grep is a compiled Lisp function in ‘em-unix.el’
~ $ which *grep
/bin/grep

Yeah, me neither, the OP is attacking this peak
from the north side at winter - step one is
getting to springy base camp which here
translates to acquiring a professional
system...

You need to install grep.exe from one of the places it's available on
the net.  Put it in the same directory where you keep emacs.exe, or
some other directory on your PATH.
