[CentOS] are there reference lists/cheat sheets for categorized commands?

  prepping to teach a 5-day CompTIA linux+ course next week with
CompTIA-supplied courseware and, given that it was my choice, i chose
to set up the classroom with centos 7.4 on all the student systems
since i assume most students are there to learn sysadmin and that's
the most likely platform they'll have when they get back to work.
also, most students are taking this course to prep for the subsequent
LPI exams to get their certification, which plays into my question.

  while the C/W is not bad, it's awfully verbose, and it would be
handy if there were concise cheat sheets of commands/files related to
the standard sysadmin they'll be expected to answer questions on. as
an example, regarding user/group management, i'm collecting all of the
relevant commands that they need to know about, in the sense of, "if
you understand these commands, you should be fine."

  regarding user/group admin, my tentative list of commands would be:

  * user{add,mod,del}
  * group(add,mod,del}
  * passwd, gpasswd
  * chage, chsh, chfn
  * pwck, grpck
  * pwconv, pwunconv

not sure what i'm missing here, i just typed those off the top of my
head.

  rather than scatter all of that over an entire chapter, are there
any official centos/rhel reference sheets like that? if not, i can
just write my own and post them at my wiki. thanks for any pointers.
