in thread How to take only maximum directory name by using its digits using perl?

Did i made any mistakes with my code.

This isn't an SSCCE. You have neither declared nor defined $output_dir and therefore $location is undefined so LOGFILE cannot be opened and your while (<LOGFILE>) condition will never be true.

Let me know to check it?

Item 1 of the Basic debugging checklist is to use the stricture pragmas. This would have highlighted the problem to you.
