# Change Path below to reflect when script is being executed on local. eg `bash $HOME/Downloads/Alphabet-MkDirs.sh`

# AUTHOR: PREETPAL BASSON
# PURPOSE: Make Directory from A to Z using current Directory. Will make either Normal or Static directories. Static means directory will not be deleted as empty, 
# PREREQUISITE: Execute from Current Directory to creates new Directories
