https://linuxvox.com/blog/automatically-run-a-program-on-startup-under-linux-ubuntu/
We start by creating a .sh file in /usr/bin/mycommand.sh
Enter the following text in it.
#!/bin/sh
sudo ip route add 10.30.24.0/24 via 192.168.0.1 dev eth0 onlink
Creating a new service:
sudo nano /etc/systemd/system/mycommand.service # create new service file
Enter the following text in it.
[Unit]
Description=Add route command
After=network.target
[Service]
Type=oneshot
ExecStart=/bin/bash /usr/bin/mycommand.sh
User=root #running as root user
Restart=never # do not restart the service if it fails
[Install]
WantedBy=multi-user.target
Starting the service:
sudo systemctl daemon-reload # reload the system daemon
sudo systemctl start mycommand.service # to start without rebooting for testing
sudo systemctl status mycommand.service # to verify status of service.
sudo systemctl enable mycommand.service # enable the service to run at startup
Removing a systemdservice
Sudo systemctl stop mycommand.service # stop the service
Sudo systemctl disable mycommand.service # disable the service
Sudo rm /ect/systemd/system/mycommand.service
