.Sh NAME
|
|
.Nm fsck_msdos
|
|
.Nd DOS/Windows (FAT) file system consistency checker
|
|
.Sh SYNOPSIS
|
|
.Nm fsck_msdos
|
|
.Op Fl fnpy
|
|
.Ar filesystem
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility verifies and repairs
|
|
.Tn FAT
|
|
file systems (more commonly known as
|
|
.Tn DOS
|
|
file systems).
|
|
It checks the specified filesystem and tries to repair all
|
|
detected inconsistencies, requesting confirmation before
|
|
making any changes.
|
|
.Pp
|
|
If the
|
|
.Fl p
|
|
flag is given,
|
|
.Nm
|
|
preens the specified filesystem.
|
|
It is normally started this way by
|
|
.Xr fsck 8
|
|
run from
|
|
.Xr rc 8
|
|
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 options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl f
|
|
This option is ignored by
|
|
.Nm fsck_msdos ,
|
|
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
|
|
Assume a
|
|
.Dq no
|
|
response to all questions asked by
|
|
.Nm
|
|
except for
|
|
.Dq CONTINUE? ,
|
|
which is assumed to be affirmative.
|
|
The filesystem will not be opened for writing.
|
|
This is the default for file systems to be checked that are
|
|
concurrently mounted writable.
|
|
.It Fl p
|
|
Preen the specified filesystem.
|
|
.It Fl y
|
|
Causes
|
|
.Nm
|
|
to assume
|
|
.Dq yes
|
|
as the answer to all operator questions.
|
|
.El
|
|
.Pp
|
|
If neither of the
|
|
.Fl y
|
|
or
|
|
.Fl n
|
|
options are specified, the user may force
|
|
.Nm
|
|
to assume an answer of
|
|
.Dq yes
|
|
to all the remaining questions by replying to a question with a value of
|
|
.Dq F .
