# 
# recursively finds "hidden" .DS_store files under the directory
# from which this command is run, then offers delete prompt
#
# if you have just downloaded this file, open iterm.app, drag
# this file into the terminal window and drop it to insert the file's 
# path into the command line. Then add 'chmod +x ' to the left side of 
# the command line and hit enter. Should look something like:
# 
# $ chmod +x ~/Users/USERNAME/Downloads/delete-all-ds_store.command
# 
# this updates the permissions on this script so it can be executed.
# 
# to use:
# 
# 1. open iTerm.app,
# 
# 2. navigate to the folder containing the .DS_Store files to be removed
#   - note: use the 'cd' command to change directories
#   - note: use the 'ls' command to list directory contents
#       - 'ls .' -> list current dir contents
#       - 'ls ../PARENT_FOLDER/SIBLING_FOLDER' -> list contents of
#          sibling folder ('..' means relative to parent folder)
#   - note: use the '~' tilde symbol as a unix shortcut for your HOME 
#       directory 
#   - note: use the 'pwd' command to print the full path of the 
#       (current) "working" directory your terminal is "in"
#   - example: to get to the folder 'TPS_Reports/' stored on your
#       Desktop, type `cd ~/Desktop/TPS_Reports`
# 
#  3. drag-and-drop this 'delete-all-ds_store.command' file into the 
#      terminal and hit enter
#   - alternatively, execute the script providing the path to it on disk,
#       then hit enter. Example: if the script is in the parent   
#       directory, execute "../delete-all-ds_store.command"
