Output a Zelda-style heart meter for your MacBook's battery level. On the command line. Based on an idea from @stephencelis, executed by myself. For a tmux version, see https://gist.github.com/4324139
#!/usr/bin/env zsh
#
# Works best with blinking text; the last heart will blink
# when you have less than 25% of your battery life remaining.
BATTERY="$(pmset -g ps | awk 'NR==2' | perl -pe 's/.*?(\d+)%.*/\1/')"
if [[ $BATTERY -lt 25 ]]; then
echo "\e[5;31m♥\e[0;31m♡♡\e[0m"
elif [[ $BATTERY -lt 50 ]]; then

Quick guide to installing rbenv
# Clone rbenv into ~/.rbenv
git clone git@github.com:sstephenson/rbenv.git ~/.rbenv
# Add rbenv to your PATH
# NOTE: rbenv is *NOT* compatible with rvm, so you'll need to
# remove rvm from your profile if it's present. (This is because
# rvm overrides the `gem` command.)
echo 'export PATH="$HOME/.rbenv/bin:$HOME/.rbenv/shims:$PATH"' >> ~/.bash_profile
exec $SHELL
