Re: Simple log parser I hope!

picabotwo,
The difficulty in your question is that your limited data sample requires us to assume a lot. The following works with the data provided.

#!/usr/bin/perl
use constant MAX_OPEN_CALLS => 100;
use strict;
use warnings;

my $log = $ARGV[0] or die "Usage: $0 <log_file>";
open(my $fh, '<', $log) or die "Unable to open '$log' for reading: $!"
+;

my %call;

{
    local $/ = '==============================================';
    while (<$fh>) {
        my ($type, $id, $info) = parse_rec($_);
        if ($type eq 'INIT') {
            next if $info !~ /TCH/;
            die "Multiple calls with id '$id' without response" if exi
+sts $call{$id};
            $call{$id} = undef;
        }
        elsif ($type eq 'RESPONSE') {
            next if ! exists $call{$id};
            print "Call with id '$id' has a Px,Py of '$info'\n";
            delete $call{$id};
        }        
        die "Too many unanswered calls" if keys %call > MAX_OPEN_CALLS
+;
    }
}

sub parse_rec {
    my ($rec)   = @_;
    my ($type)  = $rec =~ /CALL_(\w+)/;
    $type       = '' if ! defined $type;
    my ($id)    = $rec =~ /TRAN_ID\s+(\S+)/;
    my $info;
    if ($type eq 'INIT') {
        ($info) = $rec =~ /CHAN_TYPE\s+(\S+)/;
    }
    elsif ($type eq 'RESPONSE') {
        ($info) = $rec =~ /Px,Py\s*=\s*(\S+)/;
    }
    $info       = '' if ! defined $info;
    return ($type, $id, $info);
}

Hash table was exactly what I was looking for. Thanks again! Josh	[reply]

Thanks that code worked exactly as I needed it. I just did a few small small tweaks to get it do to what I needed! #!/usr/bin/perl use constant MAX_OPEN_CALLS => 100; use strict; use warnings; #my $log = $ARGV[0] or die "Usage: $0 <log_file>"; #open(my $fh, '<', $log) or die "Unable to open '$log' for reading: $! +"; my %call; { local $/ = '=============================================='; while (<>) { my ($type, $id, $info) = parse_rec($_); print "$_\n\n"; if ($type eq 'INIT') { next if $info !~ /TCH/; $call{$id} = 1; } elsif ($type eq 'RESPONSE') { next if ! exists $call{$id}; print "Call with id '$id' has a Px,Py of '$info'\n"; print "===============================================\n"; (my @args) = $info =~ /(.{8})(.{8}),(.{8})(.{8})/; #print "@args\n"; my $cprogram = `./decrypt @args`; print $cprogram; print "===============================================\n"; delete $call{$id}; } die "Too many unanswered calls" if keys %call > MAX_OPEN_CALLS +; } } sub parse_rec { my ($rec) = @_; my ($type) = $rec =~ /CALL_(\w+)/; $type = '' if ! defined $type; my ($id) = $rec =~ /TRAN_ID\s+(\S+)/; my $info; if ($type eq 'INIT') { ($info) = $rec =~ /CHAN_TYPE\s+(\S+)/; } elsif ($type eq 'RESPONSE') { ($info) = $rec =~ /Px,Py\s=\s(\S+)/; } $info = '' if ! defined $info; return ($type, $id, $info); } [download]	[reply] [d/l]
