Need help searching for text in files using command line
I am trying to find out if any files on my website are referencing a particular javascript file. How can I do this over ssh using command line tools? I have tried something like this:
grep -l 'detect_flash.js' *.php
But it just searches files within that directory, not all files recursively. I need to search all files on the server, including inside directories.
Thanks for any help,

This should do it:
find /home/user/public_html/ -name "*".php -type f -print0 | xargs -0 grep "detect_flash.js" | uniq -c | sort -u | cut -d":" -f1Just replace /home/user/pulic_html/ with the path to search. I came across this command when searching for malicious scripts. More information can be found at this article.

When I do that it says:
find: bad option -print0
find: path-list predicate-list
xargs: illegal option -- 0

Can't you just tack on a -r to grep recursively?

That's what I thought but it doesn't work either, says that -r is an illegal option.
pr0gr4mm3r - it's an apache/linux server. Not sure the details on that though. I've had some other weird problems with command line tools on it though so maybe I should bug the sys admins...
Edit: server admin told me this is on Solaris, which doesn't have the same kind of tools as Gnu/linux

The command works on my CentOS (Redhat-based) server, and my Ubuntu (Debian-based) desktop. Not sure why it wouldn't work on yours, and the linked article doesn't mention any compatible problems.

grep -e 'pattern' -r directory
…always works for me. I use it several times a day.
If -r is really an illegal option for your grep for some reason, try:
grep -e 'pattern' -d recurse
If that still doesn't work, time for good ol' man grep. Its man page is pretty monstrous, but if you search around for "recursively," you ought to find a solution.
