Shell search and replace

Can anyone suggest me free shell script which can search (and replace) desired string in multiple files... for instance, Id like to replace any instance of string in all sites pages I host at certain server, so script should recursively go thru all folders & files under /home partition and replace all instances with something...

 

Sounds like you just need

perl -pi -e 's/foo/bar/' *

To replace foo with bar in all files.

 

The problem with that is that it wont do recursive thing, than search only for files in current folder... anyhow, I found solution in rpl, which has -R option -- somebody might find it usefull, so I decided to post it here.
