FSCK.EROFS(1)               General Commands Manual              FSCK.EROFS(1)

NAME
       fsck.erofs - tool to check an EROFS filesystem's integrity

SYNOPSIS
       fsck.erofs [OPTIONS] IMAGE

DESCRIPTION
       fsck.erofs is used to scan an EROFS filesystem IMAGE and check the
       integrity of it.

OPTIONS
       -V, --version
              Print the version number of fsck.erofs and exit.

       -d #   Specify the level of debugging messages. The default is 2, which
              shows basic warning messages.

       -p     Print total compression ratio of all files including compressed
              and non-compressed files.

       --device=path
              Specify an extra blob device to be used together.  You may give
              multiple --device options in the correct order.

       --extract[=directory]
              Test to extract the whole file system. It scans all inode data,
              including compressed inode data, which leads to more I/O and CPU
              load, so it might take a long time depending on the image size.

              Optionally extract contents of the IMAGE to directory.

       --[no-]xattrs
              Whether to dump extended attributes during extraction (default
              off).

       -h, --help
              Display help string and exit.

       -a, -A, -y
              These options do nothing at all; they are provided only for
              compatibility with the fsck programs of other filesystems.
