DESCRIPTION

       The  command can be used to patch up a damaged file system after a crash.  It is intended for experienced users only.  The file system type
       to be debugged is specified as FStype.  Each file system type has a unique structure requiring different debugging capabilities.  The  man-
       ual entries for the file-system-specific should be consulted before attempting any debugging or modifications.

   Options and Arguments

	      special	     The file name of the special file containing the file system.

	      Specify the file system type on which to operate (see
			     fstyp(1M)	and  fs_wrapper(5)).   If  this  option  is not included on the command line, then the file system type is
			     determined from the file by matching special with an entry in that file.  If there is no entry in then the file  sys-
			     tem type is determined from the file

	      Specify suboptions specific to each file system type.
			     specific_options  is  a  comma-separated  list of suboptions and/or keyword/attribute pairs supported by the specific
			     FStype.

	      Echo the completed command line, but perform no other action.
			     The command line is generated by incorporating the user-specified options and  other  information	derived  from  the
			     file.  This option allows the user to verify the command line.
