Code:
find / -type f -exec grep  -l foobar {} \;

You have probably hit some character special file that has a readlock on it. You don't want to read tty files anyway. This returns the names of file with the string 'foobar' in them.

So any way to avoid it hitting files with readlock on it?
There should be some way to successfully search the entire filesystem for a string.

Thanks Again
