in reply to Textarea boxes in CGI

The three line-endings I've encountered are \n from UNIX, \r\n from DOS, and \r from some Mac's. I usually preprocess multiline strings from forms with: 
s/\r\n/\n/g;
s/\r/\n/g;

This puts everything in UNIX-style line endings.

You could also do this in your split: 

split(/\r\n|\r|\n/,$s)

; this is probably a little faster, and saves you a chomp.

    so a general input filter that leaves us with unix line endings for all three would be

    s/\r\n?/\n/g;

    Thanks everyone!... I ended up using the 2nd suggestion above. Although I was slightly overwhelmed by the number of varying responses :). Keep in mind that I am primarily a python person... but I understand TIMTOWTDI (in perl).
