Name
fsck
Synopsis
fsck [options] [filesystem] ...
Description
System administration command. Call the filesystem checker for the appropriate system type, to check and repair filesystems. If a filesystem is consistent, the number of files, number of blocks used, and number of blocks free are reported. If a filesystem is inconsistent, fsck prompts before each correction is attempted. fsck’s exit code can be interpreted as the sum of all of those conditions that apply:
- 1
Errors were found and corrected.
- 2
Reboot suggested.
- 4
Errors were found but not corrected.
- 8
fsck encountered an operational error.
- 16
fsck was called incorrectly.
- 128
A shared library error was detected.
Options
- --
Pass all subsequent options to filesystem-specific checker. All options that fsck doesn’t recognize will also be passed.
- -r
Interactive mode; prompt before making any repairs.
- -s
Serial mode.
- -t fstype
Specify the filesystem type. Do not check filesystems of any other type.
- -A
Check all filesystems listed in /etc/fstab.
- -N
Suppress normal execution; just display what would be done.
- -R
Meaningful only with -A: check all filesystems listed in /etc/fstab except the root filesystem.
- -T
Suppress printing of title.
- -V
Verbose mode.
