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
