More systemd commands

  • Transient one-shot timer
    systemd-run --on-calendar='*-*-* 03:00:00' --unit=backup /usr/local/bin/backup.sh

    Spin up a throwaway timer+service without writing unit files; great for ad-hoc scheduled jobs

  • Runtime resource cap
    systemctl set-property --runtime <unit> MemoryMax=512M CPUQuota=50%

    Apply cgroup limits live without restart; --runtime keeps them volatile (gone on reboot)

  • Pending jobs queue
    systemctl list-jobs

    Show in-flight start/stop jobs to diagnose a hung boot or a unit stuck activating

  • Enable and start service
    systemctl enable --now myapp.service

    Enable at boot and start immediately in one command

  • Show failed units
    systemctl list-units --state=failed

    List all units that are in a failed state
