Hi, Below mentioned script shows the file name whose file type is 33188.

#!/usr/bin/perl -w
use strict;
use File::stat; 

sub dodir {
    opendir(DIR,$_[0]) or die "Couldn't open $_[0] directory $!";
    my $dir=$_[0];
    
    if ( $dir !~ /\/$/ ) 
    { 
        $dir .= "/";
    }
    my @List=readdir(DIR);
    closedir(DIR);
    splice(@List,0,2);
    foreach my $file (@List) {
      $file = $dir.$file;
     if( -d $file) { dodir($file); }
     elsif (stat($file)->mode == 33188 ) { print "\n File $file is pre
+sent in $dir"; 
print "\n File type: ",stat($file)->mode; }
    }
    
}

my $dir_name="/home";
if ( -d $dir_name) {
    dodir($dir_name); 
}
