What and where in Linux depends on it's conformity to LHS (or is LSH)..
System V wise:
init.d ---> rc.d (symlink)
rc.d contains all the System V type start/stop scripts
plus a directory for each run-level rc3.d, rc5.d etc.
in rc.d/rcX.d are symlinks of the type ../program for
each thing to be started/stopped according to runlevel.
There are two links for each program, one starts with S
and one with K. The S is for start the K is for kill.
Ergo, I suppose you can see a list of what may or may not be running in
any run-level, say run-level 3, by looking at an ls listing of
rc.d/rc3.d.
Except of course this means nothing. Since some of the programs may not
be daemons (just things that run, do something, then exit), or may only
run conditionally under other circumstances (environment settings for
example). And then again you have /etc/rc.config.d .. but enough !
In short you see what is running by using "ps" on either system.
Flags used depends on O/S (as explained below), although I believe
Linux versions of "ps" understand the BSD options as well.
