I like to use shutdown -h TIME/+DELAY sometimes. However, since the switch to systemd (on Ubuntu), things seem to have changed quite a bit.

Apart from the fact that a previous shutdown command no longer prevents running a new one, I can't figure out how to check for the planned shutdown time of a current shutdown process.

I used to just run ps aux | grep shutdown to see the planned shutdown time.

Now with systemd it just shows something like this:

root      5863  0.0  0.0  13300  1988 ?        Ss   09:04   0:00 /lib/systemd/systemd-shutdownd

How can I check the scheduled shutdown time of such a process?

I tried shutdown -k, but instead of only writing a wall message, it seems to also change the scheduled shutdown time to now+1 minute.

    Me: "surely there's a simple way to view a pending shutdown, maybe some combination of arguments to shutdown that I overlooked?" SO: "here's a bunch of awk scripts, obsolete systemd invocations, and log parsing commands that might give you the info" Me: 😳

  • Upvoted as "useful", because yes, it should be an argument to the shutdown command! Maybe someone will see this and add it some day... :)

  • It seems that systemd developers are not very interested in updating the shutdown as it is just a compat layer to systemd features now, see github.com/systemd/systemd/issues/11928...

Reset to default
19 
# cat /run/systemd/shutdown/scheduled
USEC=1537242600000000
WARN_WALL=1
MODE=poweroff

The USEC is a unix epoch timestamp with microsecond precision, so:

if [ -f /run/systemd/shutdown/scheduled ]; then
  perl -wne 'm/^USEC=(\d+)\d{6}$/ and printf("Shutting down at: %s\n", scalar localtime $1)' < /run/systemd/shutdown/scheduled
fi

will display something like:

Shutting down at: Tue Sep 18 03:50:00 2018

Systemd version is 232-25+deb9u4 running on Debian Stretch .

Most simple: (and working on Debian/Ubuntu and RedHat)

date --date @$(head -1 /run/systemd/shutdown/scheduled |cut -c6-15)

    Thanks. I found the systemctl method more intuitive, but since it stopped working, this seems to be the simplest solution for newer systems. (just tested on Kubuntu 20.04) Should I accept your answer instead now? Either way, it is here for whoever might need it now. :)

  • it's kind of weird, i have a schedule at 5:58PM which is 10hours from now, but using date it shows me 5:58, not 17:58

  • Works for me on 20.04. If no shutdown is scheduled, /run/systemd/shutdown/scheduled won't exist.

All systemd versions

Use the org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager ScheduledShutdown D-Bus interface:

USECS=$(busctl get-property org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager ScheduledShutdown | cut -d ' ' -f 3)
SECS=$((USECS / 1000000))
date --date=@$SECS

Only systemd versions < May 2015

# systemctl status systemd-shutdownd.service

You should see something like this:

● systemd-shutdownd.service - Delayed Shutdown Service
Loaded: loaded (/lib/systemd/system/systemd-shutdownd.service; static; vendor preset: enabled)
Active: active (running) since Tue 2015-09-15 09:13:11 UTC; 12s ago
Docs: man:systemd-shutdownd.service(8)
Main PID: 965 (systemd-shutdow)
Status: "Shutting down at Tue 2015-09-15 09:18:11 UTC (poweroff)..."
CGroup: /system.slice/systemd-shutdownd.service
       └─965 /lib/systemd/systemd-shutdownd

Status is Shutting down at Tue 2015-09-15 09:18:11 UTC (poweroff)...

  • There is no systemd-shutdownd.service with redhat 8.

For newer linux distributions versions you might need to do:

busctl get-property org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager ScheduledShutdown

The method of how shutdown works has changed

Tried on: - Debian Stretch 9.6 - Ubuntu 18.04.1 LTS

    The output specifies the shutdown time as microseconds since the Unix epoch. To get a human-readable time: date -d @$(( $(busctl get-property org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager ScheduledShutdown | cut -d' ' -f3) / 1000000 ))

I encountered the same question and found another way to check the shutdown plan.

When you set a shutdown plan, wall will send a message to everybody logged in with their mesg permission set to yes. For every invocation of wall a notification will be written to syslog. To search the syslog, you could run the command journalctl -u systemd-shutdownd, the -u option could filter the log by unit.

When you run journalctl -u systemd-shutdownd, it will show the shutdown details like below:

[root@dev log]# journalctl -u systemd-shutdownd
-- Logs begin at Mon 2017-06-12 09:39:34 CST, end at Mon 2017-06-12 14:05:04 CST. --

On an Ubuntu 18.04 machine shutdown is managed by systemd. On my machine I have enabled automatic reboots via unattended upgrades:

$ grep Automatic-Reboot /etc/apt/apt.conf.d/50unattended-upgrades
Unattended-Upgrade::Automatic-Reboot "true";
Unattended-Upgrade::Automatic-Reboot-Time "02:00";

The scheduled automatic reboot time is stored in /run/systemd/shutdown/scheduled.

$ cat /run/systemd/shutdown/scheduled
USEC=1563976800000000 
WARN_WALL=1
MODE=reboot

You can convert this to a human readable time using the following command:

$ date -d "@$( awk -F '=' '/USEC/{ $2=substr($2,1,10); print $2 }' /run/systemd/shutdown/scheduled )"
