Name
dosfsck
Synopsis
dosfsck [options] device
fsck.ext2 [options] device
Description
System administration command. Similar to fsck, but specifically intended for MS-DOS filesystems. When checking an MS-DOS filesystem, fsck calls this command. Normally dosfsck stores all changes in memory, then writes them when checks are complete.
Options
- -a
Automatically repair the system; do not prompt the user.
- -A
Use the Atari version of the MS-DOS filesystem.
- -d file
Drop the named file from the file allocation table. Force checking, even if kernel has already marked the filesystem as valid. dosfsck will normally exit without checking if the system appears to be clean.
- -l file
Consult file for a list of bad blocks, in addition to checking for others.
- -n
Ensure that no changes are made to the filesystem. When queried, answer “no.”
- -p
“Preen.” Repair all bad blocks noninteractively.
- -t
Display timing statistics.
- -v
Verbose.
- -y
When queried, answer “yes.”
- -B size
Expect to find the superblock at size; if it’s not there, exit.
- -F
Flush buffer caches before checking.
- -L file
Consult file for list of bad blocks instead of checking filesystem for them.
