Re: How do I recursively process files through directories

[xbmy]

Ten years passed, we still are very interested in this problem, I got some code to get the total number of files under a directory, sub directory is also included.

#!/usr/bin/perl
use strict;
use warnings;

my $location = "the path of directory you want to process";  #root dir
+ectory
my $n = 0;
readsub($location);
print "Found $n file(s)!\n";   #print the total number of files you fo
+und
exit;

sub readsub {
  my ($file_t) = @_;
  if (-f $file_t) {                  #if its a file
     $n++;                           #the total number of files
  } 
  if (-d $file_t) {                  #if its a directory
     opendir(AA,$file_t) || return;
     my @list = readdir(AA);
     closedir (AA);
     my $file_to_act;
     foreach $file_to_act (sort @list) {
       if ($file_to_act =~ /^\.|\.$/) { next; }
       else { readsub("$file_t/$file_to_act"); }
     }
  }
}

Enjoy!
