NAME

mongofiles – MongoDB GridFS Utility

SYNOPSIS

The mongofiles utility makes it possible to manipulate files stored in your MongoDB instance in GridFS objects from the command line. It is particularly useful as it provides an interface between objects stored in your file system and GridFS.

All mongofiles commands have the following form:

mongofiles <options> <commands> <filename>

The components of the mongofiles command are:

1.

Options. You may use one or more of these options to control the behavior of mongofiles.

2.

Commands. Use one of these commands to determine the action of mongofiles.

3.

A filename which is either: the name of a file on your local’s file system, or a GridFS object.

mongofiles, like mongodump, mongoexport, mongoimport, and mongorestore, can access data stored in a MongoDB data directory without requiring a running mongod instance, if no other mongod is running.

IMPORTANT: For replica sets, mongofiles can only read from the set’s ‘primary.

OPTIONS

mongofiles

–help, -h

Returns information on mongofiles options and usage.

–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 mongofiles 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 mongofiles release number.

–host <hostname><:port>

Specifies a resolvable hostname for the mongod that holds your GridFS system. By default mongofiles attempts to connect to a MongoDB process running on the localhost port number 27017.

Optionally, specify a port number to connect a MongoDB instance running on a port other than 27017.

–port <port>

Specifies the port number when the MongoDB instance is not running on the standard port of 27017. You may also specify the port number using the –host option.

–ipv6

Enables IPv6 support, which allows mongofiles to connect to the MongoDB instance using an IPv6 network. All MongoDB programs and processes, including mongofiles, disable IPv6 support by default.

–ssl

New in version 2.6.

Enables connection to a mongod or mongos that has SSL support enabled.

The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure-ssl.

–sslCAFile <filename>

New in version 2.6.

Specifies the .pem file that contains the root certificate chain from the Certificate Authority. Specify the file name of the .pem file using relative or absolute paths.

The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure-ssl.

–sslPEMKeyFile <filename>

New in version 2.6.

Specifies the .pem file that contains both the SSL certificate and key. Specify the file name of the .pem file using relative or absolute paths.

This option is required when using the –ssl option to connect to a mongod or mongos that has sslCAFile enabled without sslWeakCertificateValidation.

The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure-ssl.

–sslPEMKeyPassword <value>

New in version 2.6.

Specifies the password to de-crypt the certificate-key file (i.e. –sslPEMKeyFile). Use –sslPEMKeyPassword only if the certificate-key file is encrypted. In all cases, mongofiles will redact the password from all logging and reporting output.

If the private key in the PEM file is encrypted and you do not specify –sslPEMKeyPassword, mongofiles will prompt for a passphrase. See ssl-certificate-password.

The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure-ssl.

–sslCRLFile <filename>

New in version 2.6.

Specifies the .pem file that contains the Certificate Revocation List. Specify the file name of the .pem file using relative or absolute paths.

The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure-ssl.

–sslAllowInvalidCertificates

New in version 2.6.

Bypasses the validation checks for server certificates and allows the use of invalid certificates. When using the sslAllowInvalidCertificates setting, MongoDB logs as a warning the use of the invalid certificate.

The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure-ssl.

–sslFIPSMode

New in version 2.6.

Directs mongofiles to use the FIPS mode of the installed OpenSSL library. Your system must have a FIPS compliant OpenSSL library to use –sslFIPSMode.

The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure-ssl.

–username <username>, -u

Specifies a username with which to authenticate to a MongoDB database that uses authentication. Use in conjunction with the –password and –authenticationDatabase options.

–password <password>, -p

Specifies a password with which to authenticate to a MongoDB database that uses authentication. Use in conjunction with the –username and –authenticationDatabase options.

–authenticationDatabase <dbname>

New in version 2.4.

Specifies the database that holds the user’s credentials. If you do not specify an authentication database, mongofiles assumes that the database specified as the argument to the –db option holds the user’s credentials.

–authenticationMechanism <name>

New in version 2.4.

Specifies the authentication mechanism. By default, the authentication mechanism is MONGODB-CR, which is the MongoDB challenge/response authentication mechanism. In MongoDB Enterprise, mongofiles also includes support for GSSAPI to handle Kerberos authentication. See http://docs.mongodb.org/manual/tutorial/control-access-to-mongodb-with-kerberos-authentication for more information about Kerberos authentication.

–dbpath <path>

Specifies the directory of the MongoDB data files. If used, the –dbpath option enables mongofiles to attach directly to local data files without a running mongod. When run with –dbpath, mongofiles locks access to the data directory. No mongod can access the same path while the process runs.

–directoryperdb

When used in conjunction with the corresponding option in mongod, allows mongofiles to access data from MongoDB instances that use an on-disk format where every database has a distinct directory. This option is only relevant when specifying the –dbpath option.

–journal

Allows mongofiles operations to use the durability journal to ensure data files remain valid and recoverable. This option is only relevant when specifying the –dbpath option.

–db <database>, -d

Specifies the name of the database on which to run mongofiles.

–collection <collection>, -c

This option has no use in this context and a future release may remove it. See SERVER-4931 for more information.

–local <filename>, -l

Specifies the local filesystem name of a file for get and put operations.

In the mongofiles put and mongofiles get commands, the required <filename> modifier refers to the name the object will have in GridFS. mongofiles assumes that this reflects the file’s name on the local file system. This setting overrides this default.

–type <MIME>

Provides the ability to specify a MIME type to describe the file inserted into GridFS storage. mongofiles omits this option in the default operation.

Use only with mongofiles put operations.

–replace, -r

Alters the behavior of mongofiles put to replace existing GridFS objects with the specified local file, rather than adding an additional object with the same name.

In the default operation, files will not be overwritten by a mongofiles put option.

COMMANDS

list <prefix>

Lists the files in the GridFS store. The characters specified after list (e.g. <prefix>) optionally limit the list of returned items to files that begin with that string of characters.

search <string>

Lists the files in the GridFS store with names that match any portion of <string>.

put <filename>

Copy the specified file from the local file system into GridFS storage.

Here, <filename> refers to the name the object will have in GridFS, and mongofiles assumes that this reflects the name the file has on the local file system. If the local filename is different use the mongofiles –local option.

get <filename>

Copy the specified file from GridFS storage to the local file system.

Here, <filename> refers to the name the object will have in GridFS, and mongofiles assumes that this reflects the name the file has on the local file system. If the local filename is different use the mongofiles –local option.

delete <filename>

Delete the specified file from GridFS storage.

EXAMPLES

To return a list of all files in a GridFS collection in the records database, use the following invocation at the system shell:

mongofiles -d records list

This mongofiles instance will connect to the mongod instance running on the 27017 localhost interface to specify the same operation on a different port or hostname, and issue a command that resembles one of the following:

mongofiles-- port 37017 - d records list mongofiles-- hostname db1.example.net - d records list mongofiles-- hostname db1.example.net-- port 37017 - d records list

Modify any of the following commands as needed if you’re connecting the mongod instances on different ports or hosts.

To upload a file named 32-corinth.lp to the GridFS collection in the records database, you can use the following command:

mongofiles -d records put 32-corinth.lp

To delete the 32-corinth.lp file from this GridFS collection in the records database, you can use the following command:

mongofiles -d records delete 32-corinth.lp

To search for files in the GridFS collection in the records database that have the string corinth in their names, you can use following command:

mongofiles -d records search corinth

To list all files in the GridFS collection in the records database that begin with the string 32, you can use the following command:

mongofiles -d records list 32

To fetch the file from the GridFS collection in the records database named 32-corinth.lp, you can use the following command:

mongofiles -d records get 32-corinth.lp
