I'm not much of a user of terminal commands,
shutsdown Mint and turns my computer off. Off is off, it's not in any low power mode. From your previous comment, it seems that it does this for you too
. If so, why look for another path to accomplish the same thing?
This discussion was about keyboard shortcuts. It was of interest to me as I have occasionally had my PC freeze up or hang in the middle of shutting down. So I used the information that others supplied and that I found via search to set up some keyboard shortcuts that might be of use to me for that situation, since the old "REISUB" never seems to do anything and "ctl-alt-backspace" often is no help either. I made keyboard shortcuts with some of the "session-logout" commands and the "xkill" that was suggested, as well as one with "shutdown now". I haven't had a need to use any since, but I have my notes to remember what I set up, should the machine get stuck in future.
All of that is just to let you know that I am not really an independent source of information on the details of terminal commands. I just gave you my interpretation of what I read in the thread and elsewhere. Some sources seem to indicate that shutdown, halt, and poweroff are all effectively the same when used on a PC running a Ubuntu based distro, such as Mint
