# Version: 2.3 # |
||||
# File: ~/apps/tree/tree.sh # |
||||
# # |
||||
# Displays Structure of Directory Hierarchy # |
||||
# ------------------------------------------------- # |
||||
# This tiny script uses "ls", "grep", and "sed" # |
||||
# in a single command to show the nesting of # |
||||
# sub-directories. The setup command for PATH # |
||||
# works with the Bash shell (the Mac OS X default). # |
||||
# # |
||||
# Setup: # |
||||
# $ cd ~/apps/tree # |
||||
# $ chmod u+x tree.sh # |
||||
# $ ln -s ~/apps/tree/tree.sh ~/bin/tree # |
||||
# $ echo "PATH=~/bin:\${PATH}" >> ~/.profile # |
||||
# # |
||||
# Usage: # |
||||
# $ tree [directory] # |
||||
# # |
||||
# Examples: # |
||||
# $ tree # |
||||
# $ tree /etc/opt # |
||||
# $ tree .. # |
