# Apple Silicon laptops with firmware > 13.0 have a native charge threshold that does not required any userspace daemon running.
# This native limit works even when the laptop is sleeping or powered off therefore it is preferable to the userspace daemon.
# Nonetheless, it only works with fixed thresholds (80% as upper limit and 70% as lower limit).
# CHWA key is the one used to enable/disable the native limit. 01 = 80% limit, 00 = no limit

Timers provided by systemd can be used as cronjob replacements. More at man systemd.timer.

Suppose we want to periodically trigger cleanup tasks for a baz utility. We 'll create a baz-cleanup.service which will be triggered by a baz-cleanup.timer.

Define the target service unit

Create a minimal service at /etc/systemd/system/baz-cleanup.service:

This is an example of a socket-activated per-connection service (which is usually referred to as inetd-like service). A thorough explanation can be found at http://0pointer.de/blog/projects/inetd.html.

Define a socket unit

The key point here is to specify Accept=yes, which will make the socket accept connections (behaving like inetd) and pass only the resulting connection socket to the service handler.

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

The example below creates a TCP server listening on a stream (i.e. SOCK_STREAM) socket. A similar approach can be followed to create a UDP server on a datagram (i.e. SOCK_DGRAM) socket. See man systemd.socket for details.

An example server

Create an simple echo server at /opt/foo/serve.py.
