nix quick reference

Written 2016-09-25


Nix is a package manager, noteworthy for... well, a lot of things; it's a functional package manager with a rather beautiful mixture between source and binary packaging, used as the basis for NixOS but capable of running on other UNIX-likes as a secondary package manager. I most enjoy this last point; it's nice to have a secondary package manager that's independent of the host system.

Note that this page assumes you have a general understanding of Nix but need a reminder of exact commands.
