# Nix Package Manager
|
|
|
|
## Add packages
|
|
|
|
```bash
|
|
nix-env -iA nixpkgs.<packagename>
|
|
```
|
|
|
|
If using flakes:
|
|
|
|
```bash
|
|
nix profile add nixpkgs#package-name
|
|
```
|
|
|
|
## Run a command
|
|
|
|
```bash
|
|
nix-shell -p hello --run "hello"
|
|
```
|
|
|
|
If using flakes:
|
|
|
|
```bash
|
|
nix shell nixpkgs#hello -c hello
|
|
```

# NixOS
|
|
|
|
## Updating a Flake based system
|
|
|
|
```bash
|
|
sudo nix update --flake /etc/nixos
|
|
sudo nixos-rebuild switch
|
|
```
|
|
|
|
## Updating a non-Flake based system
|
|
|
|
```bash
|
|
sudo nixos-rebuild switch --upgrade
|
|
```
|
|
|
|
You can use `boot` instead of `switch` for the system to boot into the new generation on reboot instead.
