Basically, `$message =~ s/[\r\n]+$//;` does a substitution on the string `$message`, replacing one or more (`[...]+`) characters in the given class (`[\r\n]`, the escape sequences for carriage return and line feed), as long as they're right before the end of the string (`$`). That's a really bare explanation of the regular expression; see perlrequick and perlretut for more detail. Regular expressions are one of Perl's sharpest tools: they can help you get a lot of work done in a hurry, but they aren't easy to use. Spending some time learning about them would be a good idea, but don't get discouraged if you don't "get it" right away. `-- F o x t r o t U n i f o r m Found a typo in this node? /msg me The hell with paco, vote for Erudil!`	[reply] [d/l] [select]

You might also want to check out this tutorial. It's a great intorduction to regexps from Simon Cozen's book, Beginning Perl, Wrox Press. Matter of fact, you'll probably want to read the whole book here. It's a great gentle introduction to most of Perl.	[reply]
