|
|
install a package:
|
|
`nix-env -i hello` <-- not reproducible and hence not advisable
|
|
or
|
|
edit `/etc/nixos/configuration.nix` to ensure system wide install
|
|
`nixos-rebuild switch` <-- create new generation
|
|
`nixos-rebuild test` <-- only active while computer on
|
|
|
|
`sudo nixos-rebuild test -I nixpkgs=~/usr/nixpkgs/`
|
|
^-- use local repo to build pkgs
|
|
|
|
find out where in the store a binary is:
|
|
`readlink -f $(which hello)`
|
|
|
|
search packages
|
|
`nix-env -qaP '.*hello.*'`
|
|
or
|
|
`nix search <pkg>`
|
|
|
|
search nix package options
|

`nixos-option <option>`
|
|
|
|
clear up space:
|

`nix-collect-garbage -d`
|

upgrade to new channel:
|

`nix-channel --list` # show what version we're on
|
|
`nix-channel --add https://nixos.org/channels/nixos-XX.XX nixos`
|
|
`nix-channel --update`
|
|
`nixos-rebuild switch`
|
|
|
|
use a package through nix-shell:
|
|
`nix-shell -p <package>`
|
|
|
|
list generations
|
|
`nix-env --list-generations`
|
|
|

`nixos-option environment.systemPackages`

or
|

`nix-env --query`
