# FILE: setup.sh

# USAGE: ./setup.sh
|
|
# DESCRIPTION: after pulling/cloning dotfiles repo, this script will check/create
|
|
# symlinks for for dotfiles. It checks for the presence of installed
|
|
# software (i.e. won't symlink a dotfile for applications that aren't
|
|
# installed) and will remove links for applications that are no longer
|
|
# installed. Safe to run after every git pull
|
|
# OPTIONS:
|
|
# REQUIREMENTS: This script replies on the 'command' command. Basically, it will run
|
|
# `command -v <dotfile>` and if there is no output, it assumes the app
|
|
# isn't installed. So this won't work for apps that aren't in your $PATH
