# Simplifying NixOS-Related Commands
|
|
|
|
To simplify NixOS-related commands, I utilize a Makefile, which proves to be very convenient.
|
|
|
|
Alternatively, you can also use similar tools like [just](https://github.com/casey/just) and [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 Makefile looks:
|
|
|
|
>**NOTE**: The target names in the Makefile should not conflict with any file or directory names in the current directory. Otherwise, the targets will not execute.
|
|
|
|
```makefile

deploy:

nixos-rebuild switch --flake . --use-remote-sudo

debug:

nixos-rebuild switch --flake . --use-remote-sudo --show-trace --verbose

|
|
nix flake update

history:
|
|
nix profile history --profile /nix/var/nix/profiles/system
|
|
|

gc:
|
|
# remove all generations older than 7 days
|
|
sudo nix profile wipe-history --profile /nix/var/nix/profiles/system --older-than 7d
|
|
|
|
# garbage collect all unused nix store entries
|
|
sudo nix store gc --debug

add-idols-ssh-key:

ssh-add ~/.ssh/ai-idols
|
|
|

aqua: add-idols-ssh-key
|
|
nixos-rebuild --flake .#aquamarine --target-host aquamarine --build-host aquamarine switch --use-remote-sudo
|
|
|
|
aqua-debug: add-idols-ssh-key
|
|
nixos-rebuild --flake .#aquamarine --target-host aquamarine --build-host aquamarine switch --use-remote-sudo --show-trace --verbose
|

|
ruby: add-idols-ssh-key
|
|
nixos-rebuild --flake .#ruby --target-host ruby --build-host ruby switch --use-remote-sudo
|
|
|
|
ruby-debug: add-idols-ssh-key
|
|
nixos-rebuild --flake .#ruby --target-host ruby --build-host ruby switch --use-remote-sudo --show-trace --verbose
|
|
|
|
idols: aqua ruby
|
|
|
|
idols-debug: aqua-debug ruby-debug
|
|
```
|
|
|
|
By Save the above Makefile to the root directory of your Nix flake. Then, I can use `make deploy` to deploy the configuration to my local machine, and `make 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 Makefile, providing a more user-friendly and convenient experience. |
