I am beginner in perl .My goal is to get path name of a folder from user & count total number of files and sub-directories in it using recursive function .

example : "Main" is main folder name which contains 2 subfolders SUB1 & SUB2 and 2 files mainfile1.txt,mainfile2.txt . Under each sub folder 1-file is there such as subfile1.txt & subfile2.txt in their respective folders.



-------
My snippet heer does to count number of subfolders -

#!/usr/bin/perl

use File::Find;

$dir = '.';

finddepth(\&ren_dir, $dir);

$count=0;
sub ren_dir {
next unless (-d);
$tot=$count++ ;
print "we are now inside :";
print($_ );
print "\n";
}
print "Total no of subdirectories under folder $dir= $tot";

------

Required o/p -

Main folder contains 2 files & 2 subfolders .
SUB1 folder contains 1 file
SUB2 folder contains 1 file

Totally Main folder contains 4 files & 2 subnfolders.

i don't know how to seperate the files & directories inside the folder .. my assumation of (-d) is to check whether the value is directory type..but still not clear . Please help me at the earliest .




Thanks.

Here you have script for traversing directory and counting number of subdirectories and files within.
#!/usr/bin/perl 
 
use strict;
use warnings;
 
 
my $dirCount=0;
my $fileCount=0;
 
my $dir='.';
 
countDir($dir);
 
sub countDir 
{
  my ($root) = @_;
  my @files = <$root/*>;
 
  foreach my $file (@files) 
  {
    print "found: $file\n";
    if (-d $file)
    {
      $dirCount++;
      countDir($file);
    } else
    {
      $fileCount++;
    }
      
  }
 
}
 
print "Total No of subdirectories under folder $dir= $dirCount with $fileCount of files";

Modified version of my 1st traversing script. Writes number of subdirs, files by directory and also overall total.
#!/usr/bin/perl 
 
use strict;
use warnings;
 
 
my $dirCount=0;
my $fileCount=0;
 
my $dir='.';
 
countDir($dir);
 
sub countDir 
{
  my ($root) = @_;
  my @diskOjbs = <$root/*>;
  my $dirCountLoc=0;
  my $fileCountLoc=0;
 
  foreach my $item (@diskOjbs) 
  {   
    if (-d $item)
    {
      $dirCount++;
      $dirCountLoc++;
      countDir($item);
    } else
    {
      $fileCount++;
      $fileCountLoc++;
    }      
  }
  print "$dirCountLoc subdirectory(s) under folder '$root' with $fileCountLoc file(s)\n";
 
}
 
print "Total directory(s) $dirCount with file(s) $fileCount";
