This will work, but has two drawbacks:

	1) It prints an error message about every directory it
encounters.

	2) If you happen to have a binary file which includes
"mystring", the ``line'' printed to the screen can garble the entire
screen.

Therefore, I suggest using the following command instead:

   find / ! -type d -exec grep -q "mystring" {} ; -print

The `-q' switch caused `grep' to only report whether the file contains
the string via its exit status, rather than printing the line with
that string.

If you want to exclude executable programs, say this:

   find / ! -type d -exec ! -perm 0755 grep -q "mystring" {} ; -print

`find' is part of GNU Findutils (v2gnu/find41b.zip).
