NAME¶
mongofiles - MongoDB
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 take arguments in three groups:
- 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 file name representing either the name of a file on your
system's file system, 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.
- Note
- For replica sets, mongofiles can only read
from the set's ' primary.
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.
OPTIONS¶
- --help
- Returns a basic help and usage text.
- --verbose, -v
- Increases the amount of internal reporting returned on the
command line. Increase the verbosity with the -v form by including
the option multiple times, (e.g. -vvvvv.)
- --version
- Returns the version of the mongofiles utility.
- --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 ruining 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, if the MongoDB instance is not
running on the standard port. (i.e. 27017) You may also specify a
port number using the mongofiles --host command.
- --ipv6
- Enables IPv6 support that 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 2.4: MongoDB added support for SSL
connections to mongod instances in mongofiles.
- Note
- SSL support in mongofiles is not compiled into the default
distribution of MongoDB. See /administration/ssl for more
information on SSL and MongoDB.
Additionally, mongofiles does not support connections to mongod
instances that require client certificate validation.
Allows
mongofiles to connect to
mongod instance over an SSL
connection.
- --username <username>, -u
<username>
- Specifies a username to authenticate to the MongoDB
instance, if your database requires authentication. Use in conjunction
with the mongofiles --password option to supply a password.
- --password <password>, -p
<password>
- Specifies a password to authenticate to the MongoDB
instance. Use in conjunction with the mongofiles --username option
to supply a username.
If you specify a --username without the --password option,
mongofiles will prompt for a password interactively.
- --authenticationDatabase <dbname>
- New in version 2.4.
Specifies the database that holds the user's (e.g --username)
credentials.
By default, mongofiles assumes that the database specified to the
--db argument holds the user's credentials, unless you specify
--authenticationDatabase.
See userSource, /reference/privilege-documents and
/reference/user-privileges for more information about delegated
authentication in MongoDB.
- --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 the MongoDB Subscriber Edition,
mongofiles also includes support for GSSAPI to handle
Kerberos authentication.
See /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 interact with the GridFS data without the mongod.
To run with --dbpath, mongofiles needs to lock access to the
data directory: as a result, no mongod can access the same path
while the process runs.
- --directoryperdb
- Use the --directoryperdb in conjunction with the
corresponding option to mongod, which allows mongofiles when
running with the --dbpath option and MongoDB uses 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 when running with --dbpath to ensure that the
database maintains a recoverable state. This forces mongofiles to
record all data on disk regularly.
- --db <db>, -d <db>
- Use the --db option to specify the MongoDB database
that stores or will store the GridFS files.
- --collection <collection>, -c
<collection>
- This option has no use in this context and a future release
may remove it. See SERVER-4931 for more information.
- --local <filename>, -l <filename>
- 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>, t <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.
USE¶
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
