fsdb -- filesystem debugger (generic)

Synopsis

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

Description

fsdb is a filesystem debugger which allows for the manual repair of a filesystem after a crash. special is a special device used to indicate the filesystem to be debugged. fsdb is intended for experienced users only. FSType is the filesystem 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.

fsdb processes supplementary code set characters according to the locale specified in the LC_CTYPE environment variable [see LANG on environ(5)], except that the ``f'' or ``="'' symbols do not display multibyte characters correctly.

current_options are options supported by the s5-specific module of fsdb. Other FSTypes do not necessarily support these options. specific_options indicate suboptions specified in a comma-separated list of suboptions and/or keyword-attribute pairs for interpretation by the FSType-specific module of the command.

The options are:


-F
Specify the FSType on which to operate. If -F FSType is not specified it will be determined by matching the special with an entry in /etc/vfstab. If this fails, heuristics similiar to those used by fstyp(1M) are used to determine the file system type.


NOTE: If the FSType is known beforehand, use the -F option. This command executes faster if it is not required to autodetect file system types.


-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 should be used to verify and validate the command line.

-o
Specify FSType-specific options.
