Just open a terminal in the directory holding the file you want to verify, or cd to it, run that command (don't forget TAB is a real time saver with auto filling the file name after you have typed the first few letters), wait for the return (can be a full minute if the file is largish), copy the resulting number, CTRL+F in the web page or document with the correct hash, and paste into the search field to see if you got the match.
There is software to do this but I really dislike installing software if there is a simple built-in solution. It is one of my personality traits or character flaws.
Ok have fun checking the integrity of your files!
