Guys, check out:
http://wiki.lpi.org/wiki/LinuxEssentials#1.2.2_Choosing_an_Operating_System
It's meant as a choosing between different OSes and distros (maybe
someone can justify a MS solution, too).

I added 'locate' to help/man section. nothing on how the locate db
gets updated, though.

Guys, I doubt that the questions would go beyond the level of:
find | xargs grep | cut
I'd rather people learn that than:
find -exec grep | cut
Besides, after the first combo, they should be ready for litany of
humdrum commands that they'll discover.

They deftly avoid calling them anything, I think:
http://pubs.opengroup.org/onlinepubs/009695399/utilities/ls.html
-a
Write out all directory entries, including those whose names begin
with a period ( '.' ). Entries beginning with a period shall not be
written out unless explicitly referenced, the -a option is supplied,
or an implementation-defined condition shall cause them to be
written.
If anyone can find a universal term for them, update the wiki.
