# 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 ..
