To run a (short-lived) 1 command at startup using systemd, you can use a systemd unit of type OneShot.I have decided to create my own Runescape 2 world switcher client. 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). The command must always be given with the full path. If any command fails, the rest aren't run. 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 instead. This should work with 16.04 onwards, but not earlier releases of Ubuntu with systemd (since those still used Upstart for user sessions).
User session units can be controlled with the same commands as with system services, but with the -user option added: systemctl -user daemon-reload Note that, unlike Upstart, systemd doesn't run the Exec* commands through a shell. It performs some limited variable expansion and multiple command (separated by ) itself, but that's about it as far as shell-like syntax goes.
There are different ways to automatically run commands:įor anything more complicated, say redirection or pipes, wrap your command in sh -c '.' or bash -c '.'. The upstart system will execute all scripts from which it finds a configuration in directory /etc/init.
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. 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.
