Re^2: Multiple patterns match in a big file and track the counts of each pattern matched

I tried this. It works, but it takes more than 3 and a half minutes. I guess because of grep, but i am not sure. Thanks for your time.

Yes, that's probably the reason. What about embedded code? `my %matched; my $i; my $regex = join '\|', map +($i++, "$_(?{\$matched{$i}++})")[1], map qu +otemeta, @pat_array; open my $LOG,'<', $InLogFilePath or die "can not open file :$!"; while (<$LOG>) { use re 'eval'; chomp; /$regex/ if $. > $InStartLineNumber; } close $LOG; for my $pattern (keys %matched) { print "$pattern\t$matched{$pattern}\n"; }` [download] ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7**2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l] [select]

What about embedded code?

my %matched;
my $i;
my $regex = join '|', map +($i++, "$_(?{\$matched{$i}++})")[1], map qu
+otemeta, @pat_array;

open my $LOG,'<', $InLogFilePath or die "can not open file :$!";

while (<$LOG>) {
    use re 'eval';
    chomp;
    /$regex/ if $. > $InStartLineNumber;
}
close $LOG;

for my $pattern (keys %matched) {
    print "$pattern\t$matched{$pattern}\n";
}
