Using Grep

[mop]

I often use

cat *.txt | grep <search>

which will list all of the occurances of a string in the files with .txt extension. But the output isn't what I need.

I need to know which files the search string was actually in. Is there a way in cat or grep to output the filename?

I think there is a way. Do a man grep and see what the options are.

I had a look at the man pages and you should be able to use the '-l' option to list filenames.

grep -l

Use it like this (rather than using CAT in combination with it):

[code]
# grep <word> <file>
[code]

IE, to search all .php for body

grep body *.php

To search all files for body:

grep body *
