It's just that I started using cron to run jobs when computer boots up since 16.04. This works since Ubuntu 16.04 but probably supported much sooner. This answer still uses cron but uses a different method than the top voted answer. gnomerc script, except you don't need to know sh syntax (but neither can you use any sh programming construct).Ĭron answer implemented different from top voted This has almost the same purpose and scope of the. The menu option System -> Preferences -> Startup Applications allows you to define what applications should be started when your graphical session starts (Ubuntu predefines quite some), and add or remove them to your taste. gnomerc script is finished therefore, if you want to autostart some long-running program, you need to append & to the program invocation, in order to detach it from the running shell. Note that the session does not start until the. You can put arbitrary commands in there environment variables that you set in this script will be seen by any program that you run in your session. gnomerc in your home directory is automatically sourced each time you log in to a GNOME session. You can find a readable introduction to at: the man pages man 5 init and man 8 init give you the full details.Ī shell script named. These scripts will run during system startup (or in response to certain events, e.g., a shutdown request) and so are the place to run commands that do not interact with the user all servers are started using this mechanism. The upstart system will execute all scripts from which it finds a configuration in directory /etc/init. There are different ways to automatically run commands: For anything more complicated, say redirection or pipes, wrap your command in sh -c '.' or bash -c '.'. It performs some limited variable expansion and multiple command (separated by ) itself, but that's about it as far as shell-like syntax goes. Note that, unlike Upstart, systemd doesn't run the Exec* commands through a shell. User session units can be controlled with the same commands as with system services, but with the -user option added: systemctl -user daemon-reload This should work with 16.04 onwards, but not earlier releases of Ubuntu with systemd (since those still used Upstart for user sessions). A - before the path tells systemd to ignore a non-zero exit status (instead of considering it a failure).įor user sessions, you can create the systemd unit in ~/.config/systemd/user instead. ![]() If any command fails, the rest aren't run. The command must always be given with the full path. ![]() You can run multiple commands from the same service file, using multiple ExecStart lines: ĮxecStart=-/a/third/command ignore failure For example, create /etc/systemd/system/foo.service containing: ĭescription=Job that runs your user scriptĮssentially, this is just converting a typical Upstart job to a systemd one (see Systemd for Upstart users). Obviously, you can't do the physical things, like insert or eject USB drives, but you've got an assistant on-site who can do those things for you, if necessary.To run a (short-lived) 1 command at startup using systemd, you can use a systemd unit of type OneShot. It allows you to control the remote machine and use it, more or less, just as you would if you were sitting in front of it. That's where remote-access software comes in. Seeing the problem in-person is always helpful, but, sometimes, that's not possible. Even worse, it can put that person off adopting new technology in the future. Trying to talk someone who isn't tech-savvy through a simple procedure can be frustrating for both of you.
