Emacs command for searching in files

I want to search in all files from the current folder for macro CODE_INIT_PARAMETERS.

I can do Alt + X occur, Return CODE_INIT_PARAMETERS Return, but this shows only entries from open buffers.

Is there a way to search all files from current folder, from Emacs, without switching to M-x shell and then grep? I want to avoid grep, because for some commands (M-x occur) Emacs do jumps to offending code, and I want that too.

You can try M-x rgrep.

It will ask for:

• the directory where you want to search recursively
• a file pattern for the files you want to include in the search
• the pattern you want to search

As an extra, it will exclude source control private directories from your search (like CVS, .svn or .git).

Emacs provides a built-in command:

M-x grep RET CODE_INIT_PARAMETERS *.c

(and 'grep-find to search sub directories)

Though I prefer the interface provided by an external package igrep (which provides the commands igrep and igrep-find).

If you open a folder in dired, and mark all of the files (with 'm') you can run 'dired-do-search ('A' in my bindings). This will search all marked files. To get to the next one, run tags-loop-continue (M-,)

I have set up several ELisp functions to mark various subsets of the files (.h files, .cpp files, etc.) and to create a recursive dired to search a whole tree...
