-c cmd xfs_db commands may be run interactively (the default) or
as arguments on the command line. Multiple -c arguments
may be given. The commands are run in the sequence given,
then the program exits.
-f Specifies that the filesystem image to be processed is
stored in a regular file at device (see the mkfs.xfs(8) -d
file option). This might happen if an image copy of a
filesystem has been made into an ordinary file with
xfs_copy(8).
-F Specifies that we want to continue even if the superblock
magic is not correct. For use in xfs_metadump.
-i Allows execution on a mounted filesystem, provided it is
mounted read-only. Useful for shell scripts which must
only operate on filesystems in a guaranteed consistent
state (either unmounted or mounted read-only). These
semantics are slightly different to that of the -r option.
-l logdev
Specifies the device where the filesystems external log
resides. Only for those filesystems which use an external
log. See the mkfs.xfs(8) -l option, and refer to xfs(5)
for a detailed description of the XFS log.
-p progname
Set the program name to progname for prompts and some
error messages, the default value is xfs_db.
-r Open device or filename read-only. This option is required
if the filesystem is mounted. It is only necessary to
omit this flag if a command that changes data (write,
blocktrash, crc) is to be used.
-x Specifies expert mode. This enables the (write,
blocktrash, crc invalidate/revalidate) commands.
-V Prints the version number and exits.
