uwatch monitors the state of a systemd unit and outputs messages based on its status.

Run the following commands:

git clone https://github.com/e-tho/uwatch
cd uwatch
cargo build --release

An executable file will be generated at target/release/uwatch, which you can then copy to a directory in your $PATH.

Add the flake as an input:

uwatch.url = "github:e-tho/uwatch";

Install the package:

environment.systemPackages = [ inputs.uwatch.packages.${pkgs.system}.default ];

Specify the systemd unit to watch, along with the output for active and inactive states:

uwatch --unit myservice.service --active-output "<active_output>" --inactive-output "<inactive_output>"
