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 spe-
     cial  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  dif-
     ferent 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

           example: LOCAL=ufs

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