# Simplifying NixOS-Related Commands
|
|
|
|
To simplify NixOS-related commands, I utilize [just](https://github.com/casey/just), which proves to be very convenient.
|
|
|
|
Alternatively, you can also use similar tools like Makefile or [cargo-make](https://github.com/sagiegurari/cargo-make) for this purpose. Here, I will provide my approach as a reference.
|
|
|
|
Below is an example of how my Justfile looks:
|
|
|
|
> The latest Justfile I'm using: [ryan4yin/nix-config/Justfile](https://github.com/ryan4yin/nix-config/blob/main/Justfile)
|
|
|
|
```Makefile
|
|
# just is a command runner, Justfile is very similar to Makefile, but simpler.

```
|
|
|
|
By Save this `Justfile` to the root directory of your Nix flake. Then, I can use `just deploy` to deploy the configuration to my local machine, and `just idols` to deploy the configuration to all my remote servers.
|
|
|
|
This approach simplifies the execution of NixOS commands by abstracting them behind target names in the Justfile, providing a more user-friendly and convenient experience.
