Hey all,
What we have at work is a Themis board (VME rack SPARC system).
We have to try to have the boot time as fast as can be. What we have already done is make some filesystems read only so if power is lost then the filesystem check will not run. This is only done to the partitions that... (2 Replies)

Hi, I need a sample of a script that will check a specific directory multiple times throughout the day, and scp the newest file to another server.
Example: current file is misc_file.txt_02272011 (the last part is the date), once that has been secure copied, another one may come in later the... (1 Reply)

halt
HALT(8) Linux System Administrator's Manual HALT(8)NAME
halt, reboot, poweroff - stop the system.
SYNOPSIS
/sbin/halt [-n] [-w] [-d] [-f] [-i] [-p] [-h]
/sbin/reboot [-n] [-w] [-d] [-f] [-i]
/sbin/poweroff [-n] [-w] [-d] [-f] [-i] [-h]
DESCRIPTION
Halt notes that the system is being brought down in the file /var/log/wtmp, and then either tells the kernel to halt, reboot or poweroff
the system.
If halt or reboot is called when the system is not in runlevel 0 or 6, in other words when it's running normally, shutdown will be invoked
instead (with the -h or -r flag). For more info see the shutdown(8) manpage.
The rest of this manpage describes the behaviour in runlevels 0 and 6, that is when the systems shutdown scripts are being run.
OPTIONS -n Don't sync before reboot or halt.
-w Don't actually reboot or halt but only write the wtmp record (in the /var/log/wtmp file).
-d Don't write the wtmp record. The -n flag implies -d.
-f Force halt or reboot, don't call shutdown(8).
-i Shut down all network interfaces just before halt or reboot.
-h Put all harddrives on the system in standby mode just before halt or poweroff.
-p When halting the system, do a poweroff. This is the default when halt is called as poweroff.
DIAGNOSTICS
If you're not the superuser, you will get the message `must be superuser'.
NOTES
Under older sysvinit releases , reboot and halt should never be called directly. From release 2.74 on halt and reboot invoke shutdown(8) if
the system is not in runlevel 0 or 6. This means that if halt or reboot cannot find out the current runlevel (for example, when
/var/run/utmp hasn't been initialized correctly) shutdown will be called, which might not be what you want. Use the -f flag if you want to
do a hard halt or reboot.
The -h flag puts all harddisks in standby mode just before halt or poweroff. Right now this is only implemented for IDE drives. A side
effect of putting the drive in standby mode is that the write cache on the disk is flushed. This is important for IDE drives, since the
kernel doesn't flush the write-cache itself before poweroff.
The halt program uses /proc/ide/hd* to find all IDE disk devices, which means that /proc needs to be mounted when halt or poweroff is
called or the -h switch will do nothing.
