I forgot where I read that so can't back it up but: "Unices are just a collection of different dialects of regex" I think the same is true for about every implementation of regex you can find. In theory it _should_ be same. Then again, so should SQL but I bet that it's actually quite hard to find a single statement that you can literally execute it on all DB servers (major ones). -- http://noneisyours.marcher.name http://feeds.feedburner.com/NoneIsYours -- http://mail.python.org/mailman/listinfo/python-list

regular expression syntax the same in Python, Perl and grep?
How similar is Python's re module (regular expressions) compared to Perl's and grep's regular expression syntaxes? I really hope regular expression syntax is sufficiently standardized that we don't have to learn new dialects everytime we move from one language or shell command to another. chris -- http://mail.python.org/mailman/listinfo/python-list
