Easy shell line look for string
 
Hi Guys..

I have a folder with a lot of subfolders and php files and no php files...

I need a command that will list all files in this main folder and look for a specific string inside of just the .php files.

what's the best way to do that?

Thanks

Read the man page for grep...type in "man grep" at the command line.
Code:
grep -H "<whatever string to look for>" *.php

One command won't do it ... You'll need to write a small script. It may even be able to be one line long, but you'll need a small set of commands.

You'll need ls, cat, grep, and, depending on your methodology, perhaps additionally wc and others.

You will probably also need man.

You can try :
Code:
grep -rln <string> /path/to/folder | grep .php
(but not very efficient)

Maybe:
Code:
find /path/to/folder -name "*.php" -print0 | xargs -0 grep -l <string>

Why wouldn't grep work, to find a string inside of a set of files?? That's exactly what it DOES.

Grep can recurse folders, but (based on the OP's question), they wanted to look inside the 'main folder' for all PHP files, and look in them for a string. That's grep...the -H flag returns which file names contain the string.
