It's not invalid -- you can create a file called -lm on a unix system if you want, you just have to be a bit sneaky about how you refer to it: % echo foo > ./-lm % ls -lm % cat ./-lm foo Sane people normally refrain from using such file names, however, because of the hassle of dealing with them. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
