# rm - logging script
# to install:
#     mv /bin/rm /bin/rrm
#     mv [this script] /bin/rm
#     chmod a+rx /bin/rm
#     chgrp and chown: make /bin/rm same as /bin/rrm
#     chmod a+rw /usr/spool/log/rm.log

# it doesn't grow too large
log=/usr/spool/log/rm.log

# record who is doing what, when, and from where
echo "`date` `id` `logname`
cwd=`pwd`
rm "$@"
