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.

                      How to label and detect the document text images

                      Image
                      1 $begingroup$ This is what I mean as document text image: I want to label the texts in image as separate blocks and my model should detect these labels as classes. NOTE: This is how the end result should be like: The labels like Block 1, Block 2, Block 3,.. should be Logo, Title, Date,.. Others, etc. Work done: First approach : I tried to implement this method via Object Detection, it didn't work. It didn't even detect any text. Second approach : Then I tried it using PixelLink. As this model is build for scene text detection, it detected each and every text in the image. But this method can detect multiple lines of text if the threshold values are increased. But I have no idea how do I add labels to the text blocks. PIXEL_CLS_WEIGHT_all_ones = 'PIXEL_CLS_WEIGHT_all_ones' PIXEL_C...
