[clue-tech] recursive grep

[Greg Knaddison]

And the version with find has finished?

Reading the man page for find it seems it handles links in a pretty
fancy way, though by default it just skips them:

-P     Never  follow  symbolic  links.  This is the default behaviour.
 When find examines or prints information a file, and the file is a
symbolic link, the information used shall be taken from the properties
of the symbolic link itself.

The man page for grep doesn't seem to mention how the recursive mode
treats links.
