Roboticus:

Thanks for your valuable input.

About forward slashes: I just included the part of my code which was accidentally excluded. I am dealing with user input and most times its two backslashes forwarded by server name and share (\\hostname\share-dir\ ).

Also i think the area where the thing going wrong at Linux environment is the rmdir $_ is feeding the directory name only and not the full path with the name.

I am getting script output like below, i added a print statement inside "findpath" like below, print " directories are $_ \n";

 directories are folder
 directories are dir2
 directories are folder
 directories are dir3
 directories are folder
 directories are dir1
 directories are .

How can i make sure the find path function returns full path for every empty directory?

The documentation for the wanted function interface for File::Find shows that it uses three variables to communicate with the function:

• $File::Find::dir is the current directory name,
• $_ is the current filename within that directory, and
• $File::Find::name is the complete pathname to the file.

So just use $File::Find::name instead of $_ to get the complete path name.

Using $File::Find::name rather has undesired effects.

When used File::Find::name with rmdir , it deletes the source directory itself ($ThisSourceDirectory=/home/ssaha/tmp/source ) upon condition being satisfied (empty directory) and not the constituent sub directories inside. The only two options i am finding safe is "rmdir $_" and "rmdir". Even though they are working as a code test on separate linux environ --on actual test script(code) is only able to delete on windows clients locally (c:\path etc format. Its not able to delete inputs such "\\hostname\share\" not even in Linux ("\usr\local\tmp") type. I think there a possibility that this is because of rmdir not getting full pathname and i am not getting how it could be achieved safely.
