BTDT a few times!
Easy to do with a typo in a script variable name e.g.
rm -fR $fopdir/
or running a script with a typo that leaves a variable undefined;
defensive coding is your friend to avoid disasters:
if [ -n "$foodir" ] && [ -d $foodir/ ]; then
/bin/rm -fR -- $foodir || exit
else
echo "Can't find directory '$foodir'"
exit 2
fi
