Hi

I have a situation were I need to display the file names that contain the searching word.
I think we can search for word in file using fgrep. But when it come to subfolders or other file how can we do that.
lets say we have root -> subfolder 1 --> file (contain text then diplay file name).
insted of search in one single file how can we do it in all file and subfolder.
It would be great if you have any sample program that has same functionality.

Thanks

If you are searching for whatever, use

grep -ir "whatever" root

fgrep --files-with-matches --recursive --no-messages 'PATTERN' /path/to/file_or_directoy
Commented:
why not

find /path/to/directory -name *PATTERN*

i believe that you are searching only for FILENAMES here and not in content.  grep searches through the files and gives you a list of maatches
Commented:
Well, what one should really do is

find /path/to/directory -name '*searchword*'

or

find /path/to/directory -name \*searchword\*

To search for files that have 'searchword' in the filename.

The pattern needs to either be quoted, or you need to escape special characters that the shell is not to interpret.


If the shell you type the 'find' command in does globbing, and you don't quote the pattern, the shell,
can replace  *PATTERN* with the list of any files in the current directory (if any) that happen
to match the pattern, before find even starts.

cd /some/path
grep -R "search-pattern" .

# there is a dot at the end of line 2

Hi,

-R switch is to recurse into directories below the current folder
-l switch will display filenames instead of matching line contents

so:

fgrep -R -l  <pattern> *


will match the files with the pattern recursively and will displayy only the names of the files.

Cheers,

Find works, but grep with the -R switch is much less system intensive, since find is likely to tap system resources if its a big file structure...

Also check out "egrep"

The -i (ignore case) and -R (recurse substructure) are our friends as KeremE points out.

man find
man grep
man egrep

basirana, could you please explain why you have chosen that one as answer? If that works for you, the comment posted a day earlier http:#17899582 should also work.
