problem with grep

problem with grep

[Stanke, Fred]

I am not a unix guy, but I've come to depend on emacs after using it for decades.

I have a problem, grep does not work.  How do I fix it?

-*- mode: grep; default-directory: "c:/Users/fstanke/Documents/" -*-
Grep started at Wed Apr 18 17:14:36

grep  -n cycles *.txt NUL
'grep' is not recognized as an internal or external command,

Install a port of GNU Grep.  There are several ports floating around
that you can use.

The obvious question is whether you have grep installed.  If you do, it
looks like emacs does not know about it.  There is a group you can
customise that might be worth looking at as well.

I can't be more helpful because I use emacs on Linux, so things are
rather different.

When I had to use Windows, I found the path of least resistance was to
install the Cygwin package.  That includes grep and lots of other
very useful Unix-y stuff, including diff which also works well with Emacs.

Since nowadays native Windows ports of all the important GNU utilities
are available, I don't think suggesting Cygwin is a good idea, because
using Cygwin programs with native Windows build of Emacs has subtle
problems which will require further non-default setups and tinkering.

People who want Cygwin (and generally like to feel almost like on a
Posix system) should install a Cygwin build of Emacs, not a native
build.

I wonder whether one should say
gnuwin32 (or unixutils?) < msys (ming?) < cygwin
is an increasing order of nixiness but also increasing order of heavyweightness?

MSYS is a fork of Cygwin, with relatively few changes, so the distance
between the two is very short.

(Both GnuWin32 and UnxUtils AFAIK offer very old ports, so they are
not what I'd suggest as the first place to look for recent ports.)

I haven't used them in a few years, but if Grep for Windows is all you
need to complete your emacs bliss, I'd start with GnuWin32.  No harm in
trying; easy to delete if it doesn't delight.

A lot of people use Git, also on Windows, typically the Git for Windows
installation. On Windows I have found the path of least resistance to be
to use the Gnu tools provided with the Git installation. There is some
talk about the file structure here:
