    [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
