Re: bin/57656: /sbin/shutdown prints message twice

Broadcast Message from bjjl%lion.mx.plus@localhost

(/dev/pts/0) at 16:45 CEST...

Just once…

I had left off the -D parameter earlier, but realised, that for a "shutdown now”, this would no longer display the services shutdown info lines (about squid terminating, nginx terminating, unmounting the drives, etc.), so being “blind”. With -D, running in the foreground, I do get the additional info lines once shutdown time has arrived. But the wall(1) is displayed twice, also when using a time longer than “now”:

bjjl@lion[pts/0]<Documents>% sudo shutdown -Dr +30

*** System shutdown message from bjjl%lion.mx.plus@localhost ***

System going down at 17:18

Shutdown at Fri Oct 13 17:18:57 2023.

There have been no changes to shutdown, this may depend on how you are
logged into the system (it uses wall(1) to send that message to all users).

Try:

echo Hi | wall

and see what you get displayed.
