in thread Simple awk question

On second thought. Almost! I need $fields to now be just that first field. Not just print the first field, it now needs to be a new variable.

I tried 
$fields = print $fields[0], "\n";

    Don't assign the return of print, just assign the value of the index array element: 

    my $field = $fields[0];
print "$field\n";

    But why not just use Perl's awk mode instead? 

    echo '2014-06-04T15:24:21-05:00 syslog_dp [0x80e00099][ftp][error] sec
+ure-backup(FBB): trans(5487)' | perl -lape '$_=$F[0]'
