in reply to Top 10 things to read when your flight is canceled

Given that it's been quite a while since I flew anywhere, and considering that I can't take my craft on a plane (for some reason crochet hooks are considered lethal weapons), I guess I would have to go with a couple of computer magazines, a crossword book and a book of Sudoku and Karuku puzzles (why are pens allowed? Aren't they mightier than the sword?).

[ovedpo15]: another question about regex. if I have a string like this: "a/b/,c/d/e,5" I would like to remove the string after the last comma so the output will be "a/b/,c/d/e" how to do so?
[Corion]: ovedpo15: You could split on comma, and then join everything together, except the last part. Or you could match and make sure that the last part has no comma, like qr!,[^,]+$!, or you could use rindex.
[ovedpo15]: But I don't know the length of the string. will it still work?
[ovedpo15]: The only thing I know is that there is a comma at the end and a value after that
[hippo]: Try it and see. Your computer won't explode.
[Corion]: length will tell you the length of a string.
[Corion]: But if you are parsing CSV, again, let me point to Text::CSV_XS, which you should use instead
