Learning Rust

There are three main concepts with Rust:

Ownership (only one variable "owns" the data at one time, and the owner is in charge of deallocating)
Borrowing (you can borrow a reference to an owned variable)
Lifetimes (all data keeps track of when it will be destroyed)

These are fairly simple concepts, but they are often counter-intuitive to concepts in other languages, so I wanted to give a shot at

	#!/usr/bin/env bash

	pid=$(pgrep gammastep)

	if [[ $1 = "toggle" ]]; then
	if pgrep -x "gammastep" > /dev/null; then
	kill -9 $(pgrep -x "gammastep");
	else
	gammastep -O ${GAMMASTEP_NIGHT:-3500} &
	fi
