Are you saying that if you write
for i in *.bak; rm $i; end
then if there is no backup file present, I will have all the files in the directory deleted ?
I hope you intend to implement "undo" :-D

Look at your example again... If *.bak does not match anything, the for loop body will execute exactly zero times. So the rm command will _never_ be run. And even if it had, running rm without any parameters doas not remove anything. So you are doubly safe.
