Adventures In Bad Ideas
Pop quiz for all those hackers out there: what's wrong with this

cron.)
Hint: The 'cd' is the fatal flaw. Why?Ouch. Ouch ouch ouch ouchThe good news is that the backups work properly. :)
here# rsh there 'cd /projects/team/task/results ; \
for i in * ; do \
if [ ! -h /net/here/projects/team/task/result/$i ] ; then \
echo Removing /projects/team/task/results/$i ; \
rm -rf $i & \

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
