.TH FSHALT 8 .SH NAME fshalt, scram, reboot \- halt any local file systems and optionally shut down or reboot the system .SH SYNOPSIS .B fshalt [ .B -r ] .br .B reboot [ .I kernelpath ] .br .B scram .SH DESCRIPTION .I Fshalt syncs and halts all local .IR cwfs (4) and .IR hjfs (4) servers. If given .BR -r , .I fshalt will then reboot the machine. Else it will invoke .I scram to shut down the machine. The halting and rebooting is done by copying all necessary commands into a .IR ramfs (4) file system and changing directory there before attempting to halt file systems, so this will work even on standalone machines with their roots on local file systems. .PP .I Reboot restarts the machine it is invoked on. If an optional .I kernelpath is specified then the machine will load and start that kernel directly instead of returning to the system rom. (see .IR cons (3)). .PP .I Scram shuts down the machine it is invoked on. .SH SOURCE .B /rc/bin/fshalt .br .B /rc/bin/reboot .br .B /sys/src/cmd/scram.c .SH SEE ALSO .IR cons (3), .IR reboot (8) .SH BUGS On standalone machines, it will be impossible to do anything if scram fails after invoking bare .IR fshalt . .I Scram is limited to the PC and requires APM or ACPI. .SH HISTORY .I Scram first appeared in 9front (May, 2011).
