Subject: Re: adding data to a file before it gets regexed

thanks all for the replies, I'm trying to parse log files.

so I got a bunch of logs in a directory, put them together and then
parse
them, I'm trying to keep a reference of the log files, so I know what
log
they came from, as I'm need to keep the file name to put it in to a
another
script.

I think from what people are suggesting I will have to use hashes, is
there
any good example log file perl scripts out there? or a good site ?

as I'm trying to take the logs that I find interesting and then display
them
on a web page using html templates

Thanks for all the help
Pat

Here's a "way" ... Hope this gives you some ideas...

SUN83-PRODWEB>more ~/foo
#! /usr/local/bin/perl
use strict;

opendir HERE, '.';
my %logs;
my $logs_total;
while (my $filenm = readdir HERE) {
        $logs_total++ if $filenm =~ 'log$';
        next unless $filenm =~ '^access_sun83.*log$';
        open LOG, $filenm;
        my $cnt;
        while (my $logdata = <LOG>) {
                $cnt++;
                }
        close LOG;
        $logs{$filenm} = $cnt;
        }
close HERE;
printf "There are %d logs HERE\n", $logs_total;
printf "I processed %d logs\n", scalar(keys %logs);
foreach my $filenm (sort keys %logs) {
        print "There are $logs{$filenm} items in $filenm\n";
        }
