Re: How to match last character of string, even if it happens to be a newline?

You don't really need a regular expression just to get the last character in a string:

$ perl -e'use Data::Dumper; $Data::Dumper::Useqq = 1; my $text_1 = "a\
+nb\nc\n"; print Dumper $text_1, "Last character: " . substr $text_1, 
+-1'
$VAR1 = "a\nb\nc\n";
$VAR2 = "Last character: \n";

On a side note : `chop` does the same job but is destructive and requires an lvalue. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice}	[reply]
