using grep in dired mode: best method for ascii files

[Patrick Drechsler]

Hi,

can somebody give my a pointer in the manual on searching a
folder (including subfolders) for a regexp? The subfolder include
many binary files. I don't want to search the later.

I've tried `grep-find', 'A' and `find-grep-dired`. Also marking
the folders of interest in dired-mode. Often enough I end up
with a grep error `123'.

What I'm looking for is a command to find a regexp within my
files containing (ascii-)code.

Thankful for pointers,

Patrick

you could use find-dired to execute something like:

find . \( -name <file-patten> -exec grep -q <in-file-search-pattern> {} \; 
\) -exec ls -lGd {} \;

find-grep-dired unfortunaly goes through all readable files it finds on its 
way. of course you could make your own extended "find-in-files-grep-dired", 
were you asked the user for a third string representing the file-pattern and 
put something like above together.

cheers, oliver

Hi Oliver,

thanks for the example and the explanation! I'll give it a try
and see how far I get with my lisp knowledge ;-)

Cheers
