A simple Bash script for project folder structuring

scaffold.sh

#! /bin/bash
#
# Scaffold creates a project directory structure like...
# ~
# |-- Desktop
# |-- Developer
# |   `-- project
# |-- Documents
# |   `-- project
# |-- Downloads
# |-- Movies
# |   `-- project
# |-- Music
# |   `-- project
# |-- Pictures
# |   `-- project
# |-- Sites
# |   `-- project
# `-- project_home
#     `-- project
#         |-- Desktop   -> ~/Desktop
#         |-- Developer -> ~/Developer/project
#         |-- Documents -> ~/Documents/project
#         |-- Downloads -> ~/Downloads
#         |-- Movies    -> ~/Movies/project
#         |-- Pictures  -> ~/Pictures/project
#         `-- Sites     -> ~/Sites/project
#    
# source this from your ~/.bash_profile with...
# $ echo "source ~/PATH/TO/scaffold.sh" >> ~/.bash_profile
