The fasthalt command halts the system and flags a subsequent reboot to skip the execution of fsck. The program creates the fastboot file, then invokes the halt program. The system start-up script contains instructions to look for the fastboot file. If present, the script removes the file and skips the invocation of the fsck command.
If the command is invoked without the -l, -n, or -q flag, the halt program logs the shutdown using the syslogd command and places a record of the shutdown in the login accounting file, /var/adm/wtmp. Using the -q and the -n flags imply the -l flag.
You must have root privileges to use this command.
