[wplug] scripting question

[Poyner, Brandon]

While this script may work for Don's purposes, I thought I would chime
in with some warnings.

If there is any concern about security you should never pipe to a shell.
For instance in this case if there happens to be a file named ;reboot;
sitting anywhere in the path the result would be the same as you typing
'blahblah ./;reboot; > ./;reboot;.bar'.  That will execute reboot twice.
If you're superuser, the box is going down.  More could be done if the
awk didn't limit you to the first field with the field separator of
space.  Limiting to the first field also prevents you from using this
script on files with spaces in their name.

Also, you probably want to be careful with with find.  Without
specifying any file types you end up finding the all directories
including './'.  You probably want to add -type f for files only.
