Re: Understanding this regex

Simpler:

sub get_dn { local#($filename);
    @ARGV = @_; map# <>, #gx,
    m# (<CN=.*?>) #gx,
    <>,
}

my($dn1) = get_dn('crap');

Simpler: Sure, also riskier (more dangerous) :) also you didn't local-ize $^I Also, '#' is the worst choice for a m//atch or s///ubstitution delimiter, it means you can't use # to comment your regular expression Never use '#' '$' '@' and '\\' as delimiters, they're the worst possible choices	[reply]
