Commands

I place my configuration (this repo) at ~/nixos.

Rebuild :

sudo nixos-rebuild switch --flake ~/nixos#{SYSTEM}

# Rebuild laptop:
sudo nixos-rebuild switch --flake ~/nixos#nyx

# Rebuild desktop
sudo nixos-rebuild switch --flake .#atlas

Running Appimage files

nix-shell -p appimage-run         # Enter nix shell with ability to run .AppImage files
appimage-run <something.AppImage> # Run AppImage

Cleanup and generations

List nix generations:

sudo nix-env -p /nix/var/nix/profiles/system --list-generations

Delete all older generations (and store entries):

sudo nix-collect-garbage --delete-old
