This option is used by .Xr autodiskmount 8 to determine whether to perform a full check before mounting a volume. .Pp The second form of .Nm preens the specified filesystems. It is normally started by .Xr fsck 8 run from .Pa /etc/rc during automatic reboot, when a FAT filesystem is detected. When preening file systems, .Nm will fix common inconsistencies non-interactively. If more serious problems are found, .Nm does not try to fix them, indicates that it was not successful, and exits. .Pp The third form of .Nm checks the specified file systems and tries to repair all detected inconsistencies, requesting confirmation before making any changes. The default behavior is to always ask for confirmation of each change. Use the -n or -y options to override this default behavior. .Pp The options are as follows: .Bl -hang -offset indent .It Fl q Causes .Nm to quickly check whether the volume was unmounted cleanly. If the volume was unmounted cleanly, then the exit status is 0. If the volume was not unmounted cleanly, then the exit status will be non-zero. In either case, a message is printed to standard output describing whether the volume was clean or dirty. .It Fl f This option is ignored by .Nm and is present only for compatibility with programs that check other file system types for consistency, such as .Xr fsck_ffs 8 . .It Fl n Causes .Nm to assume no as the answer to all operator questions, except .Dq CONTINUE? . .It Fl p Preen the specified filesystems. .It Fl y Causes .Nm to assume yes as the answer to all operator questions. .El .Sh SEE ALSO .Xr fsck 8 , .Xr fsck_ffs 8 , .Xr mount_msdos 8 .Sh BUGS .Nm is still under construction.
