?? rm -i $*
I'm having a hard time understanding why this would spawn more than one
process.

Do Unix admin fiascoes count? I once had an SA do "# chmod -R 700 /dev"
because he thought someone was inappropriately dinging something there.
Can
you imagine how many things break when /dev/null is unwritable and
unreadable? And when /dev/vx/rdsk/... (with a database on raw devices)
are
not readable or writable by Oracle?
The same fellow also once changed oracle's UID and the dba GID and did a
chown oracle:dba on all of oracle's directories and files - without
telling
anyone or shutting down the instances running on the server. Oracle hung
-
suddenly it did not own any processes or semaphores! ("ipcrm" is not the
preferred method of shutting down oracle!)
My own most embarrassing fiasco occurred many, many years ago - when I was
fairly new to Unix. I created a shell script named "rm" which did "rm -i
$*" You can imagine what happened the first time I ran it - processes
were
spawning faster than I could kill them, even with a script... It was admin
by BOB time. (BOB=Big Orange Button.) Fortunately, it was on a
development
server!
