Here's another one:
2.5 Jimmy wants to power off his computer. Which of the
commands (entered at the command line) will
cause his system to shut down and stop? (Choose the BEST
Answer)
a) shutdown
b) halt
c) reboot
d) All of the above
>From the Score Board:
25. a ... INCORRECT
>From the Man Page on RedHat 5.2:
%man halt
<Cut>
NOTES
Under previous sysvinit releases, reboot and halt should
never be called directly. From this release on halt and
reboot invoke shutdown(8) if the system is not in runlevel
0 or 6.
<Cut>
I know (I'm sure if you asked my 7yr old son he would agree) the answer
isn't C as the machine will not "stop", which also rules out D, but if
halt is to never be called directly on previous releases (and yes I
still have some 4.x machines) why would it be the preferred method,
especially if it calls shutdown anyway (I know it does the call with the
-h option, but still)?
