Hi there!
Hello,
I'm fairly new to Perl and need some help to acomplish a (simple?) task.
I extract strings from some logfiles, namely an ip-adress and bytes, by using regexes. I use a hash to store ip-adress and associated bytes.
Sounds like you have the hard part done :)
First i packed all logs in a temporary file but it was getting too big.
Instead of createing a new file that has each fuile in it (doubling the space and memeory used) process them one ata time:
my %ipbytes = ();
for my $file(@logfiles) {
open LOG, $file or die $1;
while(<LOG>) {
my ($ip,$bytes) = split /\:/, $_; # or however you get the ip and bytes from a line
$ipbytes{$ip} += $bytes; # may want top make sure $bytes is numeric to avoid possible errors
}
close LOG;
}
HTH :)
