A absolute or delta time -can be given, and periodic messages will be sent to all users warning of -the shutdown. If no message is specified on the command line, -.B shutdown -will ask for a message to be sent, unless the -.B \-q -option is set. - -.B halt -is the same as -.B "shutdown -h -q now" - -.B fasthalt -is the same as -.B "shutdown -h -q -f now" - -.B reboot -is the same as -.B "shutdown -r -q now" - -.B fastboot -is the same as -.B "shutdown -r -q -f now" - -The default delta time, if none is specified, is 2 minutes. - -Five minutes before shutdown (or immediately, if shutdown is less than five -minutes away), the -.I /etc/nologin -file is created with a message stating that the system is going down and -that logins are no longer permitted. The -.BR login (1) -program will not allow non-superusers to login during this period. A -message will be sent to all users at this time. - -When the shutdown time arrives, -.B shutdown -notifies all users, tells -.BR init (8) -not to spawn more -.BR getty (8)'s, -writes the shutdown time into the -.I /var/log/wtmp -file, kills all other processes on the system, -.BR sync (2)'s, -unmounts all the disks, -.BR sync (2)'s -again, waits for a second, and then either terminates or reboots the -system. - -Prior to unmounting all discs, the \fBSIGQUIT\fP signal is sent to the -\fBinit\fP process, which will in turn exec \fBshutdown\fP(8). This -allows for clean unmounting, even if the old inode for the \fBinit\fP -process was unlinked. If the current process ID (PID) equals 1, then -\fBshutdown\fP(8) will pause forever. -.SH OPTIONS -.TP -.B \-h -Halt the system. Do not reboot. This option is used when powering down -the system. -.TP -.B \-r -Reboot the system. -.TP -.B \-f -Fast. When the system is rebooted, the file systems will not be checked. -This is arranged by creating -.IR /fastboot , -which -.I /etc/rc -must detect (and delete). -.TP -.B \-q -Quiet. This uses a default broadcast message, and does not prompt the user -for one. -.TP -.B \-s -Reboot in single user mode. This is arranged by creating -.IR /etc/singleboot , -which -.BR simpleinit (8) -detects (and deletes). -.SH FILES -.nf -.I /etc/rc -.I /fastboot -.I /etc/singleboot -.I /etc/nologin -.I /var/log/wtmp -.I /etc/shutdown.conf -.fi -.SH CONFIG -The configuration file \fI/etc/shutdown.conf\fP is used to determine -the action to take when halting the machine. The currently supported -file format is extremely primitive. The first line must contain two -strings separated by whitespace. The first string must be -\fBHALT_ACTION\fP and the second specifies the action you wish to take -on halt. The options allowed are: -.TP -.B halt -This will simply halt the system. This is the default behaviour. -Note also that this is the fallback if another option fails. -.TP -.B power_off -This will use the kernel power shutdown facility. This is usually only -available on machines with Advanced Power Management (APM). -.TP -.I programname -This specifies a command to run to shut down the power. The first -character must be a "/". Bear in mind that this command will be run -with only the root filesystem mounted (and it will be read-only), and -no daemons running. -.SH "SEE ALSO" -.BR umount (8), -.BR login (1), -.BR reboot (2), -.BR simpleinit (8), -.BR init (8) -.SH BUGS -Unlike the BSD -.BR shutdown , -users are notified of shutdown only once or twice, instead of many times, -and at shorter and shorter intervals as "apocalypse approaches." -Some would construe this as a feature. -.SH AUTHOR -This page documents the version of -.B shutdown -originally written by Peter Orbaek (poe@daimi.aau.dk). |
