fsck_msdosfs
—
DOS/Windows (FAT) file system
consistency checker
SYNOPSIS
fsck_msdosfs |
-p [-Cf ]
filesystem ... |
fsck_msdosfs |
[-Cny ] filesystem ... |
DESCRIPTION
Thefsck_msdosfs
utility verifies and repairs FAT file
systems (more commonly known as DOS file systems).
The first form of fsck_msdosfs
preens the
specified file systems. It is normally started by
fsck(8) run from /etc/rc during automatic
reboot, when a FAT file system is detected. When preening file systems,
fsck_msdosfs
will fix common inconsistencies
non-interactively. If more serious problems are found,
fsck_msdosfs
does not try to fix them, indicates
that it was not successful, and exits.
The second form of fsck_msdosfs
checks the
specified file systems and tries to repair all detected inconsistencies,
requesting confirmation before making any changes.
The options are as follows:
-C
- Compatibility with the corresponding fsck(8) option (skip check if clean), defined to no-op.
-F
- Compatibility with the wrapper 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.
-f
- Force
fsck_msdosfs
to check “clean” file systems when preening. -n
- Causes
fsck_msdosfs
to assume “no
” as the answer to all operator questions, except “CONTINUE?
”. -p
- Preen the specified file systems.
-y
- Causes
fsck_msdosfs
to assume “yes
” as the answer to all operator questions.
