Is there a POSIX way to shutdown a UNIX machine?












6















I am searching for a POSIX command to shutdown a machine.



Is there a POSIX acceptable way to do this?



The commands I use to do this are not POSIX compatible (e.g., shutdown, reboot, halt or poweroff).



Systemd introduced systemctl to do this, but I am pretty sure that this is not POSIX, either.






posix shutdown

    Looking at unix.stackexchange.com/q/231989/3929, not even telinit 0 qualifies, which would be my "best" bet.

No, POSIX does not care about the shutting down or rebooting of a Unix system, nor about how services are started at boot.




The following areas are outside of the scope of POSIX.1-2017:




  • Graphics interfaces


  • Database management system interfaces


  • Record I/O considerations


  • Object or binary code portability


  • System configuration and resource availability



POSIX.1-2017 describes the external characteristics and facilities that are of importance to application developers, rather than the internal construction techniques employed to achieve these capabilities. Special emphasis is placed on those functions and facilities that are needed in a wide variety of commercial applications.




(from the Introduction section of the POSIX Base Definitions)



The shutdown command would fall into the "System configuration and resource availability" category, and it's not a tool that is important to application developers.




The full POSIX standard is available online.

Ĝi estis unu el la plej famaj simboloj de la malvarma milito kaj de la disdivido de Germanio. Pli ol simpla muro, la berlina muro estis fakte tuta defendokonstruaĵo kun du muroj, ena malplena strio, rondirvojo, gardturoj kaj alarmsistemoj. Dum la provo transiri la severe garditan limon al okcidenta Berlino multaj homoj estis mortigitaj. La preciza nombro de viktimoj estas pridisputita kaj ne certa; la nombroj anoncataj varias inter 86 kaj 238 mortintoj.
