Hi Monks, Below is my code for checking 90 days older files and deleting those. If file's age is less than 90 days and more than 3 days it will gzip it.

But here problem is I have around 120 directories and each directory is having around 90,000 Files. Now perl unlink command(which I am using here in my script) is much faster than Unix rm command but issue is with Unix gzip command, system "gzip $full_name" is taking more time.

Is there any better way to do this gzip. Note : My script is running for last 2 hours and it has not finished with even one directory yet 


#!/usr/bin/perl -w

use strict;

my @BASE_DIR = ("/u0001/DP/tandem_all/NewArchiveInsteadOfAtCABS/ARCHIV
+ED" );
#my @BASE_DIR = ("/export/home/fwtwc/dushyant/myscript/test/test1" );

chomp (my $today = `date '+%Y%m%d'`);
my $out_file = "output" . "$today";
open (FILE, ">>$out_file") or die "$!\n";

my $now = time();

sub go_dir {

    my $dh;
    opendir ($dh, "$_[0]") or die "$!\n";
    print FILE "Starting with directory $_[0]\n";

    foreach  (readdir $dh) {
        chomp;
        next if (/^\./);
        
        my $full_name = "$_[0]" . "/" . "$_";

        if ( -f $full_name ) {
           my $file_time = (stat($full_name))[9];
           my $diff = $now - $file_time;
           $diff = $diff / 86400;
           my $read = localtime($file_time);

           if ( $diff > 93 ) {
              print FILE "$full_name  : $diff : $read\n";
              unlink "$full_name";

           } elsif ( $diff > 3 ) {
                 next if (/\.gz/);
                 print FILE " Gziping file $full_name\n";
                 system "gzip $full_name";
             }


        } elsif ( -d $full_name ) {
              &go_dir ("$full_name");
          }

    }

}

foreach (@BASE_DIR) {
    &go_dir ("$_");
}
