Re: Matching a hex value in a string...

hex '0a' returns the number 10 (= 0x0a). To turn that into character 10, use chr(hex('0a')). But using the \x escape is easier: split /\x0a/. Which is identical to split /\n/, since your special character is just a newline.

No. `\n` is `\x0A` on Windows. (And `$/` is `\n`, since the CRLF→LF conversion occurs before the buffer is searched for the IRS.) `>perl -e"print length qq{\n} 1 >perl -e"print qq{\n} eq qq{\x0A} ?1:0 1 >perl -e"print $/ eq qq{\x0A} ?1:0 1 >echo foo\| perl -e"print length <> 4` [download] Maybe you're thinking of older Macs, where `\n` is `\x0D`.
