Mass find/replace...

[Marc Coyles]

Never had to do this so not sure where to start. Have googled and found
some solutions but they don't particularly work (see below)...

Someone has managed to inject php code into a PILE of php pages on my
webserver...

This basically brings up a pile of spam links.

I need to do a find / replace throughout the entire of the
/home/horbury/public_html directory...
I've tried 'find /home/Horbury/ -type f | xargs grep -l base64_decode'
to get a list of the files that require the operation performing, but it
comes up with an error (xargs: unterminated quote) after a few
results...

Any tips? Basically to find the above and remove it... otherwise I'll
have to resort to doing it in Dreamweaver and reuploading, which is a
major pita, or restoring from a backup (after working out when exactly
this happened and how - I'm guessing thru a teacher's out of date
wordpress install somewhere).
