Very useful for quickly creating and scheduling one-off services.
|
|
This tool mainly involves <a href="/wiki/linux.systemd.services">systemd services</a> and <a href="/wiki/linux.systemd.timers">systemd timers</a>.
|
|
</p><p>Like most systemd-related binaries, this can be run at system- and user-level (see <a href="/wiki/linux.systemd#systemd-at-user-level">systemd at user-level</a>).
|
|
</p><pre class="src-block"><code class="language-shell"># This will create a user-level service file with the given command as the task.
|
|
systemd-run --user borgmatic --config emergency-config.yaml --verbose
|
|
|
|
# Create a transient timer for the service.
|
|
systemd-run --user borg-backup@external-drive.service --on-calendar=12:00
|
|
</code></pre><p>The result should give you the generated name of the unit.
|
|
Then, they can be managed like an ordinary unit.
|
|
Unit generated this way will persist until the next boot.
|
|
If you want to manage them on a permanent basis, create the appropriate unit files for them.
