Shows interesting information in your terminal

profile.sh

#!/bin/bash
#
# Displays the following in your terminal:
#
# ╔────────────╦──────────╦─────────────╦─────────────╦───────╗
# ║ CPU: 68.7% ║ MEM: 53% ║ DISK: 788GB ║ profile.git ║ arm64 ║
# ╚────────────╩──────────╩─────────────╩─────────────╩───────╝
#
# Usage:    * To display the above in new terminals, save this script to a file
#             and add a call to the top of your ~/.profile
#           * I like to prepend it to pwd with an alias in ~/.bash_profile
#             alias pwd='~/scripts/profile.sh && \pwd'
