Description:

I have a string (actually a file name) like "41084109.udp". I want to get the first 4 chars into $var1 and the second 4 chars into $var2.

unpack is arguably more appropriate than a regex:

my $fname = '41084109.udp'; my( $v1, $v2 ) = unpack( 'a4 a4', $fname );

Simply use m//g:

my $fname = '41084109.udp'; @filename_parts = $fname =~ /(.{1,4})/g;
