Mac OSX Sierra and Go 1.6 Incompatibility

Users running on Mac OSX Sierra require the 3.2.10 or newer version of bsondump.

SYNOPSIS

The bsondump converts BSON files into human−readable formats, including JSON. For example, bsondump is useful for reading the output files generated by mongodump.

Run bsondump from the system command line, not the mongo shell.

IMPORTANT:

bsondump is a diagnostic tool for inspecting BSON files, not a tool for data ingestion or other application use.

OPTIONS

Changed in version 3.0.0: bsondump removed the −−filter, −−dbpath and the −−noobjcheck options.
bsondump

−−help

Returns information on the options and use of bsondump.

−−verbose, −v

Increases the amount of internal reporting returned on standard output or in log files. Increase the verbosity with the −v form by including the option multiple times, (e.g. −vvvvv.)

−−quiet

Runs bsondump in a quiet mode that attempts to limit the amount of output.

This option suppresses:

	•		output from database commands
	•		replication activity
	•		connection accepted events
	•		connection closed events

−−version

Returns the bsondump release number.

−−objcheck

Validates each BSON object before outputting it in JSON format. By default, bsondump enables −−objcheck. For objects with a high degree of sub−document nesting, −−objcheck can have a small impact on performance.

−−type <=json|=debug>

Changes the operation of bsondump from outputting “JSON” (the default) to a debugging format.

−−pretty

New in version 3.0.0.

Outputs documents in a pretty−printed format JSON.

−−bsonFile

New in version 3.4.

Specifies a path to a BSON file to dump to JSON. −−bsonFile is an alternative to the positional <bsonFilename> option.

By default, bsondump reads from standard input.

<bsonFilename>

The final argument to bsondump is a document containing BSON. This data is typically generated by bsondump or by MongoDB in a rollback operation.

−−outFile

New in version 3.4.

Specifies the path of the file to which bsondump should write its output JSON data.

By default, bsondump writes to standard output.

USE

Changed in version 3.4.

By default, bsondump outputs data to standard output. To create corresponding JSON files, you can use the −−outFile option:

bsondump −−outFile collection.json collection.bson

Use the following command (at the system shell) to produce debugging output for a BSON file:

bsondump −−type=debug collection.bson
