.SH SYNOPSIS
.sp
The \fI\%mongofiles\fP utility makes it possible to manipulate files
stored in your MongoDB instance in \fIGridFS\fP objects from the
command line. It is particularly useful as it provides an interface
between objects stored in your file system and GridFS.
.sp
All \fI\%mongofiles\fP commands take arguments in three groups:
.INDENT 0.0
.IP 1. 3
\fI\%Options\fP. You may use one or more of
these options to control the behavior of \fI\%mongofiles\fP.
.IP 2. 3
\fI\%Commands\fP. Use one of these commands to
determine the action of \fI\%mongofiles\fP.
.IP 3. 3
A file name representing either the name of a file on your system\(aqs
file system, a GridFS object.
.UNINDENT
.sp
\fI\%mongofiles\fP, like \fBmongodump\fP, \fBmongoexport\fP,
\fBmongoimport\fP, and \fBmongorestore\fP, can access data
stored in a MongoDB data directory without requiring a running
\fBmongod\fP instance, if no other \fBmongod\fP is running.
.IP Note
For \fIreplica sets\fP, \fI\%mongofiles\fP can
only read from the set\(aqs \(aq\fIprimary\fP.
.RE
.SH COMMANDS
.INDENT 0.0
.TP
.B mongofiles
.UNINDENT
.INDENT 0.0
.TP
.B list <prefix>
Lists the files in the GridFS store. The characters specified after
\fBlist\fP (e.g. \fB<prefix>\fP) optionally limit the list of
returned items to files that begin with that string of characters.
.UNINDENT
.INDENT 0.0
.TP
.B search <string>
Lists the files in the GridFS store with names that match any
portion of \fB<string>\fP.
.UNINDENT
.INDENT 0.0
.TP
.B put <filename>
Copy the specified file from the local file system into GridFS
storage.
.sp
Here, \fB<filename>\fP refers to the name the object will have in
GridFS, and \fI\%mongofiles\fP assumes that this reflects the name the
file has on the local file system. If the local filename is
different use the \fI\%mongofiles --local\fP option.
.UNINDENT
.INDENT 0.0
.TP
.B get <filename>
Copy the specified file from GridFS storage to the local file
system.
.sp
Here, \fB<filename>\fP refers to the name the object will have in
GridFS, and \fI\%mongofiles\fP assumes that this reflects the name the
file has on the local file system. If the local filename is
different use the \fI\%mongofiles --local\fP option.
.UNINDENT
.INDENT 0.0
.TP
.B delete <filename>
Delete the specified file from GridFS storage.
.UNINDENT
.SH OPTIONS
.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\%mongofiles\fP utility.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-host <hostname><:port>
Specifies a resolvable hostname for the \fBmongod\fP that
holds your GridFS system. By default \fI\%mongofiles\fP attempts
to connect to a MongoDB process ruining on the localhost port
number \fB27017\fP.
.sp
Optionally, specify a port number to connect a MongoDB instance
running on a port other than 27017.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-port <port>
Specifies the port number, if the MongoDB instance is not running on
the standard port. (i.e. \fB27017\fP) You may also specify a port
number using the \fI\%mongofiles --host\fP command.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-ipv6
Enables IPv6 support that allows \fI\%mongofiles\fP to connect
to the MongoDB instance using an IPv6 network. All MongoDB programs
and processes, including \fI\%mongofiles\fP, disable IPv6
support by default.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-ssl
New in version 2.4: MongoDB added support for SSL connections to \fBmongod\fP
instances in mongofiles.
.IP Note
SSL support in mongofiles is not compiled into the default
distribution of MongoDB. See \fB/administration/ssl\fP for more
information on SSL and MongoDB.
.sp
Additionally, mongofiles does not support connections to
\fBmongod\fP instances that require client certificate
validation.
.RE
.sp
Allows \fI\%mongofiles\fP to connect to \fBmongod\fP
instance over an SSL connection.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-username <username>, \-u <username>
Specifies a username to authenticate to the MongoDB instance, if your
database requires authentication. Use in conjunction with the
\fI\%mongofiles --password\fP option to supply a password.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-password <password>, \-p <password>
Specifies a password to authenticate to the MongoDB instance. Use
in conjunction with the \fI\%mongofiles --username\fP option to
supply a username.
.sp
If you specify a \fI\%--username\fP
without the \fI\%--password\fP option, \fI\%mongofiles\fP
will prompt for a password interactively.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-authenticationDatabase <dbname>
New in version 2.4.
.sp
Specifies the database that holds the user\(aqs (e.g
\fI\%--username\fP) credentials.
.sp
By default, \fI\%mongofiles\fP assumes that the database specified to the
\fI\%--db\fP argument holds the user\(aqs credentials, unless you
specify \fI\%--authenticationDatabase\fP.
.sp
See \fBuserSource\fP,
\fB/reference/privilege\-documents\fP and
\fB/reference/user\-privileges\fP for more information about
delegated authentication in MongoDB.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-authenticationMechanism <name>
New in version 2.4.
.sp
Specifies the authentication mechanism. By default, the
authentication mechanism is \fBMONGODB\-CR\fP, which is the MongoDB
challenge/response authentication mechanism. In the MongoDB Subscriber Edition,
\fI\%mongofiles\fP also includes support for \fBGSSAPI\fP to handle
Kerberos authentication.
.sp
See \fB/tutorial/control\-access\-to\-mongodb\-with\-kerberos\-authentication\fP
for more information about Kerberos authentication.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-dbpath <path>
Specifies the directory of the MongoDB data files. If used, the
\fI\%--dbpath\fP option enables \fI\%mongofiles\fP to attach directly to
local data files interact with the GridFS data without the
\fBmongod\fP. To run with \fI\%--dbpath\fP, \fI\%mongofiles\fP needs to lock
access to the data directory: as a result, no \fBmongod\fP can access
the same path while the process runs.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-directoryperdb
Use the \fI\%--directoryperdb\fP in conjunction with the corresponding
option to \fBmongod\fP, which allows \fI\%mongofiles\fP when
running with the \fI\%--dbpath\fP option and MongoDB uses an
on\-disk format where every database has a distinct
directory. This option is only relevant when specifying the
\fI\%--dbpath\fP option.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-journal
Allows \fI\%mongofiles\fP operations to use the durability
\fIjournal\fP when running with \fI\%--dbpath\fP
to ensure that the database maintains a recoverable state. This
forces \fI\%mongofiles\fP to record all data on disk regularly.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-db <db>, \-d <db>
Use the \fI\%--db\fP option to specify the MongoDB database that stores
or will store the GridFS files.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-collection <collection>, \-c <collection>
This option has no use in this context and a future release may
remove it. See \fI\%SERVER-4931\fP for more information.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-local <filename>, \-l <filename>
Specifies the local filesystem name of a file for get and put
operations.
.sp
In the \fBmongofiles put\fP and \fBmongofiles get\fP
commands the required \fB<filename>\fP modifier refers to the name
the object will have in GridFS. \fI\%mongofiles\fP assumes that
this reflects the file\(aqs name on the local file
system. This setting overrides this default.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-type <MIME>, t <MIME>
Provides the ability to specify a \fIMIME\fP type to describe the
file inserted into GridFS storage. \fI\%mongofiles\fP omits this
option in the default operation.
.sp
Use only with \fBmongofiles put\fP operations.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-replace, \-r
Alters the behavior of \fBmongofiles put\fP to replace
existing GridFS objects with the specified local file, rather than
adding an additional object with the same name.
.sp
In the default operation, files will not be overwritten by a
\fBmongofiles put\fP option.
.UNINDENT
.SH USE
.sp
To return a list of all files in a \fIGridFS\fP collection in the
\fBrecords\fP database, use the following invocation at the system shell:
.sp
.nf
.ft C
mongofiles \-d records list
.ft P
.fi
.sp
This \fI\%mongofiles\fP instance will connect to the
\fBmongod\fP instance running on the \fB27017\fP localhost
interface to specify the same operation on a different port or
hostname, and issue a command that resembles one of the following:
.sp
.nf
.ft C
mongofiles \-\-port 37017 \-d records list
mongofiles \-\-hostname db1.example.net \-d records list
mongofiles \-\-hostname db1.example.net \-\-port 37017 \-d records list
.ft P
.fi
.sp
Modify any of the following commands as needed if you\(aqre connecting
the \fBmongod\fP instances on different ports or hosts.
.sp
To upload a file named \fB32\-corinth.lp\fP to the GridFS collection in
the \fBrecords\fP database, you can use the following command:
.sp
.nf
.ft C
mongofiles \-d records put 32\-corinth.lp
.ft P
.fi
.sp
To delete the \fB32\-corinth.lp\fP file from this GridFS collection in
the \fBrecords\fP database, you can use the following command:
.sp
.nf
.ft C
mongofiles \-d records delete 32\-corinth.lp
.ft P
.fi
.sp
To search for files in the GridFS collection in the \fBrecords\fP
database that have the string \fBcorinth\fP in their names, you can use
following command:
.sp
.nf
.ft C
mongofiles \-d records search corinth
.ft P
.fi
.sp
To list all files in the GridFS collection in the \fBrecords\fP database
that begin with the string \fB32\fP, you can use the following command:
.sp
.nf
.ft C
mongofiles \-d records list 32
.ft P
.fi
.sp
To fetch the file from the GridFS collection in the \fBrecords\fP
database named \fB32\-corinth.lp\fP, you can use the following command:
.sp
.nf
.ft C
mongofiles \-d records get 32\-corinth.lp
.ft P
.fi
