[Solved]Question about a command

[willie42]

I was wondering about a command that helped someone and I was asked a question that I dont know the answer to.

Code: Select all

sudo shutdown -r -F now

what is the -F switch do.

I hope I posted this in the right area.

what is the -F switch do.

see red below

-a Use /etc/shutdown.allow.

-k Don't really shutdown; only send the warning messages to every‐
body.

-r Reboot after shutdown.

-h Halt or power off after shutdown.

-P Halt action is to turn off the power.

-H Modifier to the -h flag. Halt action is to halt or drop into
boot monitor on systems that support it. Must be used with the
-h flag.

-f Skip fsck on reboot.

-F Force fsck on reboot.

-n [DEPRECATED] Don't call init(8) to do the shutdown but do it
ourself. The use of this option is discouraged, and its results
are not always what you'd expect.

-c Cancel a waiting shutdown. ("shutdown now" is no longer wait‐
ing.) With this option it is of course not possible to give the
time argument, but you can enter explanatory message arguments
on the command line that will be sent to all users.

-t sec Tell init(8) to wait sec seconds between sending processes the
warning and the kill signal, before changing to another run‐
level.

time When to shutdown.
