Subject: Hyperbole recursive directory grep, not giving expected result

I was trying out this paragraph from DEMO file:

> The output of `grep -n', the UNIX line pattern matcher, can be activated as

> RET} or even better, the Hyperbole recursive directory grep, {C-h h f g}.

It does not do what is expected, for example if I write "facebook" in
elpa/hyperbole directory, it will not give me any results, if I do
classic grep, it gives me result

[~/.emacs.d/elpa/hyperbole-7.1.2]
admin-> grep -insIH --exclude="*~" --exclude="#*" --exclude="TAGS" -e 'facebook' .
[~/.emacs.d/elpa/hyperbole-7.1.2]
admin-> 

no result from above.

If I do like this in the shell:

grep -insIH --exclude="*~" --exclude="#*" --exclude="TAGS" -e 'facebook' *

Then I am getting some results. Please review if there is any error. 

Suggestion:

The minibuffer description: Rgrep below current dir... could actually
show the current dir to the user.

I use:  Editor:      GNU Emacs 28.0.50 (build 15, x86_64-pc-linux-gnu, X toolkit, cairo version 1.14.8, Xaw3d scroll bars)

{C-h h f g} works fine here.

Are you saying you are in a buffer whose default-directory is the
elpa/hyperbole directory and your grep returns no results?  If so, I don't
see that problem with 7.1.3.

Maybe except long paths would likely get in the way.

I am using 7.1.3 now, and it does not work:

-*- mode: grep; default-directory: "~/Programming/emacs-lisp/" -*-
Grep started at Wed Sep 30 12:12:18

grep -insIH --exclude="*~" --exclude="#*" --exclude="TAGS" -e 'rcd' .

Grep finished with no matches found at Wed Sep 30 12:12:18

while in that directory I have many many results for "rcd".

So it definitely does not work.

grep -insIH --exclude="*~" --exclude="#*" --exclude="TAGS" -e 'business' .

I don't think so it will ever work recursively, the option -r is
missing or -d recurse as in manual of grep.

And you are using . as FILE argument, but with -r option, you need no
argument at all in the directory.

I really wonder, could you tell me which system are you using? Is it
GNU/Linux or other?

Which grep is used there?

Sometimes I use GNU/Linux, sometimes MacOS.  On MacOS, I have:

grep --version
grep (BSD grep) 2.5.1-FreeBSD

The Hyperbole custom option used in this grep command is:

hypb:rgrep-command

and the default definitely includes the -r option.  Have a look in
hypb.el.  You must have customized it.

Well that maybe different, I cannot know now. It does not work on
GNU/Linux with GNU grep.

Does that work on your GNU/Linux grep?

It should work with any grep in general, you need to make sure it works.

I would never customize that, truly I did not, yet Emacs says I
did. That is weird. I never before even used that grep within
Hyperbole.

It works now.

However, I am not sure if you need the dot on the end, the
documentation says nothing need be on the end at -r recursive grep.
