fsdb - file system debugger
fsdb [-F FSType] [-V] [-o FSType-specific_options] special
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.
-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.
See largefile(7) for the description of the behavior of fsdb when
encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
/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

FSType-specific modules of fsdb.
This command may not be supported for all FSTypes.
