Byobu (over SSH) Cheat Sheet

I often find myself using Byobu on a Linux machine when connected to it over SSH. In doing so, I've noticed that many of the documented keyboard shortcuts don't work. This can be due to the native PC's OS intercepting certain keys, or possibly other reasons.

Below is a cheatsheet with Byobu features I have found usually work when run over a SSH connection.

Action	Windows + Putty to Ubuntu	MacOS + Terminal to Ubuntu
Help menu	BASH: byobu-config	FN-F1
Create new window	CTRL-a c	CTRL-a c or FN-F2

	#!/usr/bin/env bash

	# Set API key env variable like:
	# export NETBOX_API_KEY="blahblahblah"
	# Usage: ./Add_Netbox_User NETBOX_HOST USERNAME FIRST_NAME LAST_NAME EMAIL GROUP_ID PASSWORD
	# Example: ./Add_Netbox_User netbox.example.com will.riker William Riker [email protected] 1 TroiFan1

	if [[ -z "$NETBOX_API_KEY" ]]; then
	echo "Must provide NETBOX_API_KEY in environment" 1>&2
	echo " Example: export NETBOX_API_KEY='blahblahblah'" 1>&2

	# /root/newuser.sh
	#
	# Create and use a new user every time you log in.
	#
	# Setup:
	# ~$ nano newuser.sh
	# paste contents of this file and save
	# ~$ chmod +x newuser.sh
	# ~$ echo "bash newuser.sh" >> ~/.profile
