NAME

       fsdb - file system debugger (generic)

SYNOPSIS

       FStype] specific_options] special

   Remarks
       Always execute the command (see fsck(1M)) after running

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
       recognizes the following 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.

EXAMPLES

       Invoke the file system debugger on HFS file system

       Display a completed command line without executing the debugger:

       The previous command might display:

WARNINGS

       Only experienced users should use The failure to fully understand the usage of and the file system's internal organization can lead to com-
       plete destruction of the file system and total loss of data.

NAME

       fsdb - file system debugger

SYNOPSIS

       fsdb [-F FSType] [-V] [-o FSType-specific_options] special

DESCRIPTION

       fsdb  is  a  file  system debugger that allows for the manual repair of a file system after a crash.   special is a special device  used to
       indicate the file system to be debugged. fsdb is intended for experienced users only. FSType is the file system type to be debugged.  Since
       different  FSTypes  have  different  structures	and  hence different debugging capabilities, the manual pages for the FSType-specific fsdb
       should be consulted for a more detailed description of the debugging capabilities.

OPTIONS

       -F	Specify the  FSType on which to operate.  The  FSType should either be specified here or  be  determinable  from   /etc/vfstab	by
		matching the  special with an entry in the table, or by consulting /etc/default/fs.

       -V	Echo  the  complete command line, but do not execute the command. The command line is generated by using the options and arguments
		provided by the user and adding to them information derived from  /etc/vfstab. This option may be used to verify and validate  the
		command line.

       -o	Specify  FSType-specific options.

USAGE

       See largefile(5) for the description of the behavior of fsdb when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

FILES

       /etc/default/fs	       default	local file system type. Default values can be set for the following flags in /etc/default/fs. For example:
			       LOCAL=ufs

			       LOCAL:	The default partition for a command if no FSType is specified.

       /etc/vfstab	       list of default parameters for each file system

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
