RE: OT moment of doubt

Once every year we have a test rebuilding all our servers on a remote location designed to have something left in case of a real disaster. We always have a lively discussion who is allowed to execute the ultimate zap: cd /
rm -fr *
Never seen a faster performing query.
Practising it, we hope we never do this in real life :-) But you never get used to it, you always hesitate before hitting enter.

Jareds method is what I use most of the times. When I'm really unsure, I run a small loop like (Apologies Jared, this still isn't perl):
for file in *.dbf
do

   echo mv ${file} ${file}.GONE
done

When the results are OK, command history is my friend to repeat the whole thing without the echo.

After a while, the *.GONE files can safely be removed. (Be sure the essential program didn't have them opened al the time, unaware of the renaming)

Just my $0.02
