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.
