systemd Developer Lennart Poettering lennart@poettering.net systemd-notify 1 systemd-notify Notify init system about start-up completion and other daemon status changes systemd-notify OPTIONS VARIABLE=VALUE systemd-notify may be called by daemon scripts to notify the init system about status changes. It can be used to send arbitrary information, encoded in an environment-block-like list of strings. Most importantly it can be used for start-up completion notification. This is mostly just a wrapper around sd_notify() and makes this functionality available to shell scripts. For details see sd_notify3. The command line may carry a list of environment variables to send as part of the status update. The following options are understood: --h --help Prints a short help text and exits. --ready Inform the init system about service start-up completion. This is equivalent to systemd-notify READY=1. For details about the semantics of this option see sd_notify3. --pid= Inform the init system about the main PID of the daemon. Takes a PID as argument. If the argument is omitted the PID of the process that invoked systemd-notify is used. This is equivalent to systemd-notify MAINPID=$PID. For details about the semantics of this option see sd_notify3. --status= Send a free-form status string for the daemon to the init systemd. This option takes the status string as argument. This is equivalent to systemd-notify STATUS=.... For details about the semantics of this option see sd_notify3. --booted Returns 0 if the system was booted up with systemd, non-zero otherwise. If this option is passed no message is sent. This option is hence unrelated to the other options. For details about the semantics of this option see sd_booted3. On success 0 is returned, a non-zero failure code otherwise. systemd1, systemctl1, systemd.unit5, sd_notify3, sd_booted3
