in reply to Re^2: how to move the folder from one directory to another directory?
in thread how to move the folder from one directory to another directory?

But here the session folder is created dynamically along with the time stamp. Here what does file A and file B means??

The linked documentation says: The move function also takes two parameters: the current name and the intended name of the file to be moved

So move( oldname, newname )

use Path::Tiny qw/ path /; path( $oldname )->move( $newname );

    I can't say the name of the folder as it will be created dynamically with the time stamp.... So how can we move that folder without knowing the name of the folder

      Hi vasuperl,

      What can be found in that directory besides the session folder? Is it the only file/folder in the directory?

      Update: You can list all directories in the path_to_folder. 

      foreach (<path_to_sessions/*>) {
    if ( -d ) {
        print "$_\n";
        move(...
    }
}

      Additional filtering can be addded to the file glob and/or regexp match can be added to the if statement.

      It is a very simple solution. All you need to do is read an original directory. Then read your new directory. Then If new directory does not contain a file/folder in original directory, then copy it.

      Here is what i came up with a sec ago: 
      use strict;
use warnings;

use File::Copy::Recursive qw(rcopy);
use File::Slurp;
use Cwd;

my $cwd = cwd();

my $dir = $ARGV[0];

my $orig_dir = "$cwd/$dir";
my $new_dir  = "$cwd/your/path/";

my @first_scan = read_dir($orig_dir);    #this will build an initial l
+ist
                                         #and put it into @first_scan;
re_scan();

sub re_scan {                            #to rescan over and over whil
+e comparing

    my @new_scan = read_dir($new_dir);

    foreach my $element (@first_scan) {
        if ( $element ~~ @new_scan ) {
            print "$element Already Exists!\n";
        }
        else {
            print "Copying $element to $new_dir\n";
            rcopy( $orig_dir . $element, $new_dir . $element );
        }
    }
    undef(@first_scan);

    for (@new_scan) {
        push( @first_scan, $_ );
    }
    
    undef(@new_scan);
    sleep(3);
    ;
    re_scan();

}

      This should work for your scenario as you just need to scan the directory, and if the new directory does not contain somethign that the old dir has in it, it copies it.

        This code will also fill up the stack as re_scan calls itself endlessly (Perl should even have warned you about "Deep recursion"). I'd really recommend you read up on recursion (e.g. Modern Perl: Recursion) and how to turn it into iteration, for example here: http://www.refactoring.com/catalog/replaceRecursionWithIteration.html

      Hmm, first step, find out the name, path( $folder )->children
