.SH DESCRIPTION
|
|
.B e2fsck
|
|
is used to check a Linux second extended file system.
|
|
.TP
|
|
.I device
|
|
is the special file corresponding to the device (e.g /dev/hdXX).
|
|
.SH OPTIONS
|
|
.TP
|
|
.I -b superblock
|
|
Instead of using the normal superblock, use the alternative superblock
|
|
specified by
|
|
.IR superblock .
|
|
.TP
|
|
.I -d
|
|
Print debugging output (useless unless you are debugging
|
|
.B e2fsck
|
|
).
|
|
.TP
|
|
.I -f
|
|
Force checking even if the file system seems clean.
|
|
.TP
|
|
.I -F
|
|
Flush the filesystem device's buffer caches before beginning. Only
|
|
really useful for doing e2fsck time trials.
|
|
.TP
|
|
.I -l filename
|
|
Add the blocks listed in the file specified by
|
|
.I filename
|
|
to the list of bad blocks.
|
|
.TP
|
|
.I -L filename
|
|
Set the bad blocks list to be the list of blocks specified by
|
|
.IR filename .
|
|
(This option is the same as the
|
|
.I -l
|
|
option, except the bad blocks list is cleared before the blocks listed
|
|
in the file are added to the bad blocks list.)
|
|
.TP
|
|
.I -n
|
|
Open the filesystem read-only, and assume an answer of ``no'' to all
|
|
questions. Allows
|
|
.B e2fsck
|
|
to be used non-interactively. (Note: if the
|
|
.I -l
|
|
or
|
|
.I -L
|
|
options are specified in addition to the
|
|
.I -n
|
|
option, then the filesystem will be opened read-write, to permit the
|
|
bad-blocks list to be updated. However, no other changes will be made
|
|
to the filesystem.)
|
|
.TP
|
|
.I -p
|
|
Automatically repair ("preen") the file system without any questions.
|
|
The
|
|
.I -a
|
|
option is provided for backwards compatibility.
|
|
.TP
|
|
.I -t
|
|
Print timing statistics for
|
|
.BR e2fsck .
|
|
If this option is used twice, additional timing statistics are printed
|
|
on a pass by pass basis.
|
|
.TP
|
|
.I -v
|
|
Verbose mode.
|
|
.TP
|
|
.I -V
|
|
Print version information and exit.
|
|
.TP
|
|
.I -y
|
|
Assume an answer of ``yes'' to all questions; allows
|
|
.B e2fsck
|
|
to be used non-interactively.
|
|
.SH EXIT CODE
|

The exit code returned by
|
|
.B e2fsck
|
|
is the sum of the following conditions:
|

.br
|

\ 0\ \-\ No errors
|
|
.br
|
|
\ 1\ \-\ File system errors corrected
|

.br
|
|
\ 2\ \-\ File system errors corrected, system should

|
|
.br
|
|
\ 4\ \-\ File system errors left uncorrected
|
