.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility verifies and repairs
|
|
.Tn FAT
|
|
file systems (more commonly known
|
|
as
|
|
.Tn DOS
|
|
file systems).
|
|
.Pp
|
|
The first form of
|
|
.Nm
|
|
preens the specified file systems.
|
|
It is normally started by
|
|
.Xr fsck 8
|
|
run from
|
|
.Pa /etc/rc
|
|
during automatic reboot, when a FAT file system 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 second form of
|
|
.Nm
|
|
checks the specified file systems and tries to repair all
|
|
detected inconsistencies, requesting confirmation before
|
|
making any changes.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl C
|
|
Compatibility with the corresponding
|
|
.Xr fsck 8
|
|
option (skip check if clean), defined to no-op.
|
|
.It Fl F
|
|
Compatibility with the wrapper
|
|
.Xr fsck 8
|
|
which seeks to determine whether the file system needs to be cleaned
|
|
immediately in foreground, or if its cleaning can be deferred to background.
|
|
FAT (MS-DOS) file systems must always be cleaned in the foreground.
|
|
A non-zero exit code is always returned for this option.
