Does grep work in Windows

Does grep work in Windows

[-- Attachment #1.1: Type: text/plain, Size: 588 bytes --]

In emacs 22 on windows should grep work?

I am typing m-x grep which opens a line in the mini buffer that says

Run grep (like this): grep -n

and a message saying:  Grep started at Tue Jan 23 21:19:22

I then add, as shown in the grepmode wiki the following to the mini buffer

-e setq ~/.emacs

giving me a full line in the minibuffer of

Run grep (like this): grep -n -e setq ~/.emacs
hit return and get a message that says

'grep' is not recognized as an internal or external command,
operable program or batch file.

Can anyone point out what I am doing wrong.

Many thanks,

Graham

Did you install grep?  Is it in PATH?

Grep is not a native program with windows.

I installed the cygwin unix environment on my xp machine, and have
been successfully using the grep command from there for some time.

Ralf,

Thanks for the reply.

I have installed Grep from the gnuwin32 web site and "now" added it to the
PATH environmental variable. Same error.

The full error message is

*- mode: grep; default-directory: "~/" -*-
Grep started at Tue Jan 23 22:19:50

grep -n -e setq ~/.emacs NUL
'grep' is not recognized as an internal or external command,

Grep finished with no matches found at Tue Jan 23 22:19:5

Chris,

Thanks for the  reply.

I have installed the GNUWin32 version of Grep

I assume this should work with Emacs :-(

As someone else has pointed out "grep" is not a native command on MS 
Windows. To make it easier to setup Emacs on MS Windows I have therefor 
added grep and some other unix style programs to EmacsW32, see

Did you restart Emacs after installing Grep?  Emacs won't notice any
changes to PATH while it (Emacs) is running.

If you did restart Emacs, please make sure that you modified PATH
correctly, i.e. in a way that will be in effect for all programs,
including Emacs.  In practice, this means you should modify PATH via
Control Panel, not in the shell window.

This error message says that the OS cannot find grep.exe.  You need to
find out why.  Something in the way you installed Grep is not right.

[-- Attachment #1.1: Type: text/plain, Size: 1522 bytes --]

Eli,

Thanks for your help.

I did restart Emacs, indeed I re-booted the PC. I modified the PATH via My
Computer|advanced|Environmental variable, and I have re-installed Grep.

In the end I gave up and installed Emacsw32, which comes with Grep, and its
now working.

I would rather have solved the problem but, for now this seems the more
efficient way of sorting it out.

Should I have added anything in the .emacs file?

Graham

Exactly what text did you add to the PATH variable?  It should have been
the directory where grep was installed.

No.  The message that you saw is a message from Windows that indicates
that the command you have attempted to invoke, grep, can't be found in
the PATH environmental variable.  The most likely explanation for the
problem is that the path to grep you entered into the PATH
environmental variable was subtly incorrect.

Robert,

Thanks, that narrows it down, if I re-install emacs I shall know where to
look.

Some tips:-
* The path is needed exactly to the executable, in Cygwin for example
C:\cygwin\bin\
* The path must be separated by ";"s if a mistake is made in doing this
earlier in the path variable it propagates until the next ;
* A new path only goes into effect when you click OK in the dialog box.
 Then it only goes into effect for new programs from that time.  Ones
currently running are not affected.
* The environmental variables Window gives "system variables" and "user
variables".  For most Emacs purpose this doesn't matter since Emacs
will be run as whatever user you are.  But for some programs it matters
because they run sub-processes as system tasks.

Robert,

Thanks for this, I shall bear this in mind the next time I add a program to
the path. I am finding emacs a big learning experience.

On a related note, (I also use cygwin's grep + emacs), when I use grep,
I cannot follow the grep hits to the files.

In the *grep* window, I try pressing C-` or Ret on the line containing
the grep hit, but I get the message "No grep hit here".  The mode line
reads Grep:exit [matched]

Although the buffer is in grep mode it seems that none of the
keybindings are active (Ret, Tab, etc.)

Just in case that it may help, here is a sample output from grep:

It does matter if one uses the same machine under several user names,
or wants his aunt to use Emacs.  In that case, modify the system-wide
Path; otherwise only for your username.

First, unxutils is a collection of very old versions of GNU software.
It also seems to not be maintained anymore.

And second, the directory you suggested does not need to exist on a
Windows system, it can have other names.

One can use %systemroot% for that. Of course, you need write access in
that dir.

Indeed, why don't the matched lines mention the line number?  `M-x grep'
provides the -n option to the grep program by default so that its output
lines look like:

FILE:LINE NUMBER:TEXT

Third, is it really a good idea to place other binaries in this special 
directory that is suppose to contain only the OS binaries?

It certainly isn't.  And putting "find" their will probably interfer
with MS "find" as C:\Windows occurs earlier in PATH than MS find does.
This may break some batch files.

Thank you Kevin!!!!!

Adding the -n option did the thing.  I guess that in the mists of time,
I defined my grep command (in custom-set-variables) as
"e:/cygwin-root/bin/grep.exe".  I have now added the -n switch to it.

Thanks again,

Mirko

I have put exe files in c:\winnt and c:\windows for many years without
any problems. But I don't put all things there, of course.
