@ammar-web first of all your PR is invalid since you have removed most of the script and in place of that you have left a comment, that's not how this works.

second I see that you are first checking if the directory exists but I am using mkdir -p which doesn` t do anything if the directory is already present.

Next time please add a description along with the PR
