I would contend that you shouldn't even use a regex to solve this problem, since the problem pertains to decoding the data stored within a
fixed-width columnar format.
For this, the appropriate tool is unpack:
#!/perl/bin/perl
use strict;
use warnings;
use Data::Dumper;
my $str = '06/19/2007 10:50 AM <DIR> 1dfgfg';
my $spec = 'A12A12A15A10'; # adjust this spec to meet your columnar ne
+eds
my @arr = unpack($spec, $str);
print Dumper(\@arr);
print "\n";
print "username is ", $arr[3], "\n";
print "\n";
__OUTPUT__
$VAR1 = [
'06/19/2007',
'10:50 AM',
'<DIR>',
'1dfgfg'
];
username is 1dfgfg
