Search files in a folder

Search files in a folder

[노정태]

[-- Attachment #1.1: Type: text/plain, Size: 285 bytes --]

Hello.

I want to search org files in my /org folder.
But I can't find a command to search files wholly.
C-c a s (org-search-view) does search only with headline.
I can't search the contents of my org files with just one command.

Does Org-mode have the function what I'm looking for?

maybe org-mode does not but of course emacs does: M-x grep RET
or M-x occur RET

HTH,

Probably doesn't do as neatly as occur or grep, but the OP can get a
sparse tree based on a regex search.
`C-c / / <regex>'

These work just fine. Org-mode also has a built-in interface to emacs'
multi-occur function --- it searches for (and displays) all lines
containing a given regexp in one's agenda files.[1]

Simply type:

C-c a / [regexp]

E.g.

C-c a / \(org\|org-\)mode


Best,
Matt

Thank you everyone.

I learned I could do it with grep, but I don't know how to use grep
properly.

Isn't there no way to search files which are not agenda file?

grep is one of my favourite *nix tools. :)

You can try invoking grep in many ways. these are my most used options,

1. simply search for a regex and show results.
    grep -nH -E <regex> <wildcard_to_match files>
2. search for results and show results with context
    grep -nHB <number> -E <regex> <wildcard_to_match files>
    # context lines before matching lines
    grep -nHA <number> -E <regex> <wildcard_to_match files>
    # context lines after matching lines
    grep -nHC <number> -E <regex> <shell_wildcard_to_match files>
    # context lines from both before and after matching lines
3. You can try `M-x find-grep' if you want more control over what file
you want to search
    find -type f -name <shell_wildcard_to_match_files> -print0 | xargs
-0 grep -nH -E <regex>

Note: find and grep regex are a little different from emacs regex
because of some quoting differences. 'man grep' is your friend.

Suvayu, I read your comment, and googled about what I can't understand.

In Emacs, M-x grep <RET> Filename * <RET> does what I want. Thank you.

And now, I want to make it as one elisp command.

What should I do? Can anybody write a simple script?

Sincerely, Jeongtae.

FWIW, here's my elisp function to search all my org files with lgrep:

--8<---------------cut here---------------start------------->8---
  (defun my-org-grep (search &optional context)
    "Search for word in org files. 

Prefix argument determines number of lines."
    (interactive "sSearch for: \nP")
    (let ((grep-find-ignored-files '("#*" ".#*"))
	  (grep-template (concat "grep <X> -i -nH " 
				 (when context
				   (concat "-C" (number-to-string context)))
				 " -e <R> <F>")))
      (lgrep search "*org*" "/home/matt/org/")))

  (global-set-key (kbd "<f8>") 'my-org-grep)
--8<---------------cut here---------------end--------------->8---

A prefix argument (e.g., C-u 3 <f8>) will change the number of
contextual lines pulled up by the search.

Best,
Matt

Wow, It works like a magic! Thank you so much.

I wrote it to my .emacs. Thank you.

Nice - I added an entry about this in org-hacks.org.
