I started on Unix in the ‘80’s and it was to help out a friend with adding waves to a ray
tracing system he was building. I knew C at the time... my friend gave me like 5 vi
commands and sat me down in front of the terminal with a visual bell. (Luckily I don’t
have epilepsy or all that flashing would have had me in seizures :-) )
After answering about 30 questions about library calls available, he taught me the most
useful thing I ever learned for Unix. “man -k | grep <word>”. From there on out, I
was on my own and completely equipped to learn all I needed.
As a side note, when I saw Google fir the first time, I said “oh, man -k | grep for the
web....”

When I first came to Unix, I read man pages for every one of
the commands in /bin and experimented with them and tried out
various options. Being a fan of recursion the first thing I
tried was "man man"! Then I went through all the man pages in
other section to learn about libc functions, special devices
and so on. I knew about "apropos" (though don't recall if it
was in v7) but I didn't really use it all that much. Or the
inverted index.
I tend to think software has more in common with carpentry
than science or engineering and like all good craftsman,
knowing how to use all the tools in your workshop is
essential. If you get lucky you get to be an apprentice to a
good mentor but I didn't have that luxury in a startup.

I agree with Grant. If you want to know what a particular command
does and what its options are, man pages are fantastic. If you are a
new or casual user trying to find out what command(s) to use to
accomplish a particular task, the man pages are an exercise in
frustration and futility. Other OSes have done a
better job in that
area (the VMS and DTSS HELP commands come to mind). IMO ideally one
should have both--a generalized "help" command for those trying to
find out what command to use, and "man" as reference material. UNIX
and Linux have never had a proper help facility. Or at least I never
was able to find it.
I had usd VMS befoe Unix. Not for long but I don't recall its
help facility being particularly superior.
Each of us learns differently so there is no one true style.
