No, but I'll give you a command to list all of the commands that have 'process' in the description
now, that will probably show up too much stuff, so you could try something like:
apropos process| grep -i view
apropos process| grep -i report
But I will thank you for this question: As a result of checking out the various apropos commands also turned up qps, which looks quite nice. And, if you find a tree layout of the output is more useful, you could use the word 'tree' instead of 'view' or 'report'.
