[
.B \-b

This option does nothing at all; it is provided only for backwards
compatibility.
-.TP
-.B \-s
-This option will byte-swap the filesystem so that it is using the normalized,
-standard byte-order (which is i386 or little endian). If the filesystem is
-already in the standard byte-order,
-.B e2fsck
-will take no action.
-.TP
-.B \-S
-This option will byte-swap the filesystem, regardless of its current
-byte-order.
