e2fsck linux command

e2fsck

e2fsck [options] device

fsck.ext2 [options] device

System administration command. Similar to fsck, but specifically intended for Linux Second Extended Filesystems. When checking a second extended filesystem, fsck calls this command.

Options

-b superblock

Use superblock instead of default superblock.

-d

Debugging mode.

-f

Force checking, even if kernel has already marked the filesystem as valid. e2fsck 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.
