Bash Scripting: Check if a Bash Variable Has Been Set (Or Is Empty String)

	# How to determine if a bash variable is empty?


	# A variable in bash (and any POSIX-compatible shell) can be in one of three states:
	#
	# unset
	# set to the empty string
	# set to a non-empty string
	# Most of the time you only need to know if a variable is set to a non-empty string, but occasionally it's important to distinguish between unset and set # to the empty string.

How to build and use mesa from source

Building and using mesa for development and testing

This explains how to build mesa from source, and how to use the custom built mesa to run some apps and games, without needing to replace the mesa libraries that your operating system runs on.

Let's assume that you are using an x86_64 system.

Install dependencies

This is how to install them on Fedora. You can substitute with other distros' package managers, the packages are named similarly but maybe have a different naming convention (eg. -dev vs. -devel, etc.).
