in reply to How to monitor a logfile with columns for certain data?

Hello freddie,

There is also a solution by using unpack:

#!/usr/local/bin/perl -w use strict; use Data::Dumper; my $spec = 'A24A9A15A8A8A8'; my $line = scalar <DATA>; my @arr = unpack($spec, $line); print Dumper(\@arr); __DATA__ N-20070143.003.TXT 05/23/07 02:36:59 PM 13 13 0 __OUTPUT__ $VAR1 = [ 'N-20070143.003.TXT', '05/23/07', '02:36:59 PM', '13', '13', '0' ];

Where do you want *them* to go today?

[shmem]: well, previous to that << was always treated as the left-shift operator
[Eily]: or the here-doc operator
[Eily]: which is actually how it is parsed in this case
[shmem]: older versions of perl can't guess that "use of <<>> may be implemented someday" :D
