Simple systemd / systemctl

A basic systemd file:

[Unit]
Description=test

[Service]
User=andy
Type=simple
ExecStart=/home/andy/test

[Install]
WantedBy=multi-user.target

The file /home/andy/test must begin with: 

#!/bin/sh -

The core systemd commands: Not type systemctl not systemd

• sudo systemctl status test       
• sudo systemctl restart test
• sudo systemctl stop test

For when you add something to: /etc/systemd/system

• sudo systemctl daemon-reload     

Sending logs to syslog from services started by systemd:

Use the following properties in your systemd service unit file:

StandardOutput=syslog
StandardError=syslog
SyslogIdentifier= # without any quote

Then, assuming your distribution is using rsyslog to manage syslogs, create a file in /etc/rsyslog.d/.conf with the following content:

if $programname == '' then /path/to/log/file.log
& stop

restart rsyslog (sudo systemctl restart rsyslog)
