Name
e2fsck
Synopsis
e2fsck [options] device
fsck.ext2 [options] device
Description
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.
