No.  A shell is just a program (which may or may not be written in C).

"man install" will answer that.  (On my system, it's ignored; apparently
it meant something in earlier versions.)

Looking at the source would frankly be a silly way to find out what
"mkdir -p" means.  Try "man mkdir".

No.  If you're referring to "-g", that's an option that can be passed to
the gcc command.  It tells it to produce debugging information.  Again,
"man gcc" can tell you more.  "info gcc" shows the gcc documentation in
another form that's likely to be more complete (you might need to
install the "gcc-doc" package for that to work).

Incidentally, none of your questions so far are about the C language.

Again, it's an option to the gcc command.

No.

C says nothing about bash.  It's a program that happens to be written in
C.  "info bash" (if bash-doc is installed) will tell you about bash.

POSIX does impose some requirements on the behavior of the standard
shell; bash follows most of those requirements and adds some
bash-specific features.

comp.unix.programmer probably would have been a better place for most or
all of these questions.
