.SH SYNOPSIS
.sp
The \fI\%bsondump\fP converts \fIBSON\fP files into human\-readable
formats, including \fIJSON\fP. For example, \fI\%bsondump\fP is useful
for reading the output files generated by \fBmongodump\fP.
.SH OPTIONS
.INDENT 0.0
.TP
.B bsondump
.UNINDENT
.INDENT 0.0
.TP
.B \-\-help
Returns a basic help and usage text.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-verbose, \-v
Increases the amount of internal reporting returned on the command
line. Increase the verbosity with the \fB\-v\fP form by including
the option multiple times, (e.g. \fB\-vvvvv\fP.)
.UNINDENT
.INDENT 0.0
.TP
.B \-\-version
Returns the version of the \fI\%bsondump\fP utility.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-objcheck
Validates each \fIBSON\fP object before outputting it in
\fIJSON\fP format. By default, \fI\%bsondump\fP enables
\fI\%--objcheck\fP by default. For objects with a high degree of
sub\-document nesting, \fI\%--objcheck\fP can have a small impact
on performance. You can set \fI\%--noobjcheck\fP to disable
object checking.
.sp
Changed in version 2.4: MongoDB enables \fI\%--objcheck\fP by default, to prevent any
client from inserting malformed or invalid BSON into a MongoDB
database.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-noobjcheck
New in version 2.4.
.sp
Disables the default document validation that \fI\%bsondump\fP
performs on all BSON documents.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-filter \(aq<JSON>\(aq
Limits the documents that \fI\%bsondump\fP exports to only those
documents that match the \fIJSON document\fP specified as
\fB\(aq<JSON>\(aq\fP. Be sure to include the document in single quotes to
avoid interaction with your system\(aqs shell environment.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-type <=json|=debug>
Changes the operation of \fI\%bsondump\fP from outputting "\fIJSON\fP" (the
default) to a debugging format.
.UNINDENT
.INDENT 0.0
.TP
.B <bsonfilename>
The final argument to \fI\%bsondump\fP is a document containing
\fIBSON\fP. This data is typically generated by
\fBmongodump\fP or by MongoDB in a \fIrollback\fP operation.
.UNINDENT
.SH USAGE
.sp
By default, \fI\%bsondump\fP outputs data to standard output. To
create corresponding \fIJSON\fP files, you will need to use the
shell redirect. See the following command:
.sp
.nf
.ft C
bsondump collection.bson > collection.json
.ft P
.fi
.sp
Use the following command (at the system shell) to produce debugging
output for a \fIBSON\fP file:
.sp
.nf
.ft C
bsondump \-\-type=debug collection.bson
.ft P
.fi
