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 B +Ignored for +.Xr fsck 8 +compatibility. .It Fl C -Compatibility with the corresponding +Ignored for .Xr fsck 8 -option (skip check if clean), defined to no-op. +compatibility. .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. .It Fl M Causes .Nm to not use .Xr mmap 2 when checking a FAT32 file system. This option is mainly for debugging purposes and is not normally necessary. The .Nm utility will automatically fall back to use a simple LRU cache of 4 MiB when it failed to perform .Xr mmap 2 , or when .Fl M is specified. .It Fl f Force .Nm to check .Dq clean file systems when preening. .It Fl n Causes .Nm to assume .Dq Li no as the answer to all operator questions, except .Dq Li CONTINUE? . .It Fl p Preen the specified file systems. .It Fl y Causes .Nm to assume .Dq Li yes as the answer to all operator questions. .El .Sh SEE ALSO .Xr fsck 8 , .Xr fsck_ffs 8 , .Xr mount_msdosfs 8 .Sh HISTORY The .Nm utility appeared in .Nx 1.2 . .Nm first appeared in .Fx 4.4 . .Sh BUGS The .Nm utility is .Ud diff --git a/sbin/fsck_msdosfs/main.c b/sbin/fsck_msdosfs/main.c index 0713189daa2d..49a811964ab9 100644 --- a/sbin/fsck_msdosfs/main.c +++ b/sbin/fsck_msdosfs/main.c @@ -1,161 +1,162 @@ /*- * SPDX-License-Identifier: BSD-2-Clause * * Copyright (C) 1995 Wolfgang Solfrank * Copyright (c) 1995 Martin Husemann * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
