I'm always fuzzy with the exact format of entering cron jobs and I always have to Google it, but it's a starting point for ya. The command "crontab -e" allows you to edit this and add commands to the scheduler. If you want it to start up automatically on boot, you can use cron (a Linux scheduler). To end it you'll have to issue "killall programname" or "kill program'sprocessID" which can be found with the "ps" command.
If you append your command with "&" it will start up and drop back to the command line while continuing to run in the background.

If you have any question feel free to ask them. Sometimes you'll have to run "systemctl daemon-reload" after updating the configuration file, but it'll warn you if you forget. Journalctl -u mon_petit_bac_back # displays everything that was outputted by the program, add -r to see the latest messages first Systemctl status mon_petit_bac_rvice # to check on the service, see if it enabled / running, etc.

Systemctl restart mon_petit_bac_rvice # to restart it, useful after updating the node code here Systemctl disable mon_petit_bac_rvice # to stop it automatically start on boot Systemctl enable mon_petit_bac_rvice # to automatically start it on boot
Systemctl stop mon_petit_bac_rvice # to stop it if it is started Then you can run a bunch of commands: systemctl start mon_petit_bac_rvice # to launch it if it is stopped This type of file can go in many place, personally it's in /etc/systemd/system/ and the file is named mon_petit_bac_rvice The other options such as "Type" or "WantedBy" are fairly standard and I can't really remember what they're needed for. "After" with this value means it will wait for network on my RPI before starting the node app, "User" is under which Linux user to run it, "ExecStart" is the command and "Restart=on-failure" will relaunch the program if it crashes. Here is an example of mine to run a simple node application that acts as a backend for a small web game I made: ĮxecStart=/usr/local/bin/node /home/tiwenty/mon_petit_bac_git/back/index.js You can just make a configuration file with the command to launch your program, specify some parameters and you can then "enables" it, stop it, restart it. If you want to run scripts at boot or at any repetitive time, cron can do it for you.įinally, if you have programs that require always running, such as web servers or game servers, systemd is really helpful. If a command line program doesn't have such option, you can do as /u/DirtyPolecat said and add a '&' to your command. For instance, wget -b launches it in the background and you can close your terminal. Then, a lot of command line programs which can be long to run have a background option. Ok then, I think systemd could be a nice solution, depending on the type of programs you want to run in background.įirst, I'd say /u/gavwando solution with screen is great for situations when you want to occasionally launch a command which you may want to check up on or interact with later.
