.SH NAME
fsdb \- file system debugger
.SH SYNOPSIS

\fBfsdb\fR [\fB-F\fR \fIFSType\fR] [\fB-V\fR] [\fB-o\fR \fIFSType-specific_options\fR] \fIspecial\fR
.fi

.SH DESCRIPTION
.sp
.LP
\fBfsdb\fR is a file system debugger that allows for the manual repair of a
file system after a crash.   \fIspecial\fR is a special device  used to
indicate the file system to be debugged. \fBfsdb\fR is intended for experienced
users only. \fIFSType\fR is the file system type to be debugged. Since
different \fIFSTypes\fR have different structures and hence different debugging
capabilities, the manual pages for the \fIFSType-\fRspecific \fBfsdb\fR should
be consulted for a more detailed description of the debugging capabilities.
.SH OPTIONS
.sp

.na
\fB\fB-F\fR\fR
.ad
.RS 6n
.rt  
Specify the  \fIFSType\fR on which to operate.  The  \fIFSType\fR should either
be specified here or be determinable from  \fB/etc/vfstab\fR by matching the
\fIspecial\fR with an entry in the table, or by consulting
\fB/etc/default/fs\fR.

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  \fB/etc/vfstab\fR. This option may be
