# Displays structure of folder hierarchy            #
# ------------------------------------------------- #
# This tiny script uses "ls", "grep", and "sed"     #
# in a single command to show the nesting of        #
# subfolders.                                       #
#                                                   #
# Setup:                                            #
#    $ mkdir -p ~/apps/tree                         #
#    Save "tree.sh" into the "~/apps/tree" folder   #
#    $ cd ~/apps/tree                               #
#    $ chmod +x tree.sh                             #
#    $ ln -s tree.sh /usr/local/bin/tree            #
#    $ which tree                                   #
