An observation (that may be erroneous) of the output of ls: The second to last field is always the time, which contains a colon. How about matching /:\d{2}\s+.*\s+.+\b/ ? #!/usr/bin/perl use strict; use warnings; while (<DATA>) { if (/:\d{2}\s+(.*\s+.+)\b/) { print $1, "\n"; } } __DATA__ -rwxrwxrwx 1 777 22000 2971201 Jan 24 18:17 file1.zip -rwxrwxrwx 1 777 22000 9941 Jan 28 18:10 file2 onespace.zip -rwxrwxrwx 1 777 22000 3002969941 Jan 29 13:28 file3 two spaces.zip Justin. -- Justin C, by the sea.

Make it a while. The OP was not initially clear on what he wanted. So I threw something together and put it out there, to see if he would elaborate. At that early stage, starting a dialog was more important than providing elegant Perl code. Sometimes people wander into a newsgroup looking for ideas, and need a friendly helping hand more than elegant code. He seems to have disappeared though. I guess the mean people scared him away. -- Web mail, POP3, and SMTP http://www.beewyz.com/freeaccounts.php |
