It is particularly useful as it provides an interface between objects stored in your file system and GridFS. .sp All \fI\%mongofiles\fP commands have the following form: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C mongofiles .ft P .fi .UNINDENT .UNINDENT .sp The components of the \fI\%mongofiles\fP command are: .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 filename which is either: the name of a file on your local\(aqs file system, or a GridFS object. .UNINDENT .sp Run \fI\%mongofiles\fP from the system command line, not the \fBmongo\fP shell. .sp \fBIMPORTANT:\fP .INDENT 0.0 .INDENT 3.5 For replica sets, \fI\%mongofiles\fP can only read from the set\(aqs primary\&. .UNINDENT .UNINDENT .SH AVAILABILITY .sp The \fI\%mongofiles\fP tool is part of the MongoDB tools package. Consult the installation guide for your platform for instructions on how to install the tools package as part of your MongoDB installation. .sp The tools package is also available from the \fI\%MongoDB Download Center\fP, either as a separate \fBtools\fP download, or contained within the \fBTGZ\fP or \fBZIP\fP downloads, depending on platform. On Windows, the \fBMSI\fP installer includes all tools as part of the default installation. .INDENT 0.0 .INDENT 3.5 .SH TIP .sp If downloading the \fBTGZ\fP or \fBZIP\fP files from the Download Center, you may want to update your \fBPATH\fP environment variable to include the directory where you installed these tools. See the installation guide for your platform for more information. .UNINDENT .UNINDENT .SH REQUIRED ACCESS .sp In order to connect to a \fBmongod\fP that enforces authorization with the \fB\-\-auth\fP option, you must use the \fI\%\-\-username\fP and \fI\%\-\-password\fP options. The connecting user must possess, at a minimum: .INDENT 0.0 .IP \(bu 2 the \fBread\fP role for the accessed database when using the \fBlist\fP, \fBsearch\fP or \fBget\fP commands, .IP \(bu 2 the \fBreadWrite\fP role for the accessed database when using the \fBput\fP or \fBdelete\fP commands. .UNINDENT .SH BEHAVIOR .SS FIPS .sp Starting in version 4.2, MongoDB removes the \fB\-\-sslFIPSMode\fP option for mongofiles\&. mongofiles will use FIPS compliant connections to \fBmongod\fP/\fBmongos\fP if the \fBmongod\fP/\fBmongos\fP instances are configured to use FIPS mode\&. .SS Read Preference .sp By default, \fI\%mongofiles\fP uses read preference \fBprimary\fP\&. To override the default, you can specify the read preference in the \fI\%\-\-readPreference\fP command line option or in the \fI\%\-\-uri connection string\fP\&. .sp Starting in version 4.2, if you specify read preference in the URI string and the \fI\%\-\-readPreference\fP, the \fI\%\-\-readPreference\fP value overrides the read preference specified in the URI string. .sp In earlier versions, the two options are incompatible. .SS Write Concern .sp Starting in version 4.2, you can specify both the \fI\%\-\-writeConcern\fP and the \fI\%\-\-uri connection string\fP option. If write concern is specified using both options, the \fI\%\-\-writeConcern\fP value overrides the write concern specified in the URI string. .sp In earlier versions, the two options are incompatible. .SH OPTIONS .sp Changed in version 3.0.0: \fI\%mongofiles\fP removed the \fB\-\-dbpath\fP as well as related \fB\-\-directoryperdb\fP and \fB\-\-journal\fP options. To use \fI\%mongofiles\fP, you must run \fI\%mongofiles\fP against a running \fBmongod\fP or \fBmongos\fP instance as appropriate. .INDENT 0.0 .TP .B \-\-help Returns information on the options and use of \fBmongofiles\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-\-verbose, \-v Increases the amount of internal reporting returned on standard output or in log files.

Prior to MongoDB 3.0, you had to specify \fI\%\-\-ipv6\fP to use IPv6. In MongoDB 3.0 and later, IPv6 is always enabled. .UNINDENT .INDENT 0.0 .TP .B \-\-ssl New in version 2.6. .sp Enables connection to a \fBmongod\fP or \fBmongos\fP that has TLS/SSL support enabled. .sp For more information about TLS/SSL and MongoDB, see /tutorial/configure\-ssl and /tutorial/configure\-ssl\-clients . .UNINDENT .INDENT 0.0 .TP .B \-\-sslCAFile= New in version 2.6. .sp Specifies the \fB\&.pem\fP file that contains the root certificate chain from the Certificate Authority. Specify the file name of the \fB\&.pem\fP file using relative or absolute paths. .sp Starting in version 3.4, if \fB\-\-tlsCAFile\fP/\fBnet.tls.CAFile\fP (or their aliases \fB\-\-sslCAFile\fP/\fBnet.ssl.CAFile\fP) is not specified and you are not using x.509 authentication, the system\-wide CA certificate store will be used when connecting to an TLS/SSL\-enabled server. .sp To use x.509 authentication, \fB\-\-tlsCAFile\fP or \fBnet.tls.CAFile\fP must be specified unless using \fB\-\-tlsCertificateSelector\fP or \fB\-\-net.tls.certificateSelector\fP\&. Or if using the \fBssl\fP aliases, \fB\-\-sslCAFile\fP or \fBnet.ssl.CAFile\fP must be specified unless using \fB\-\-sslCertificateSelector\fP or \fBnet.ssl.certificateSelector\fP\&. .sp \fBWARNING:\fP .INDENT 7.0 .INDENT 3.5 \fBVersion 3.2 and earlier:\fP For TLS/SSL connections (\fB\-\-ssl\fP) to \fBmongod\fP and \fBmongos\fP, if the \fBmongofiles\fP runs without the \fI\%\-\-sslCAFile\fP, \fBmongofiles\fP will not attempt to validate the server certificates. This creates a vulnerability to expired \fBmongod\fP and \fBmongos\fP certificates as well as to foreign processes posing as valid \fBmongod\fP or \fBmongos\fP instances. Ensure that you \fIalways\fP specify the CA file to validate the server certificates in cases where intrusion is a possibility. .UNINDENT .UNINDENT .sp For more information about TLS/SSL and MongoDB, see /tutorial/configure\-ssl and /tutorial/configure\-ssl\-clients . .UNINDENT .INDENT 0.0 .TP .B \-\-sslPEMKeyFile= New in version 2.6. .sp Specifies the \fB\&.pem\fP file that contains both the TLS/SSL certificate and key. Specify the file name of the \fB\&.pem\fP file using relative or absolute paths. .sp This option is required when using the \fI\%\-\-ssl\fP option to connect to a \fBmongod\fP or \fBmongos\fP that has \fBCAFile\fP enabled \fIwithout\fP \fBallowConnectionsWithoutCertificates\fP\&. .sp For more information about TLS/SSL and MongoDB, see /tutorial/configure\-ssl and /tutorial/configure\-ssl\-clients . .UNINDENT .INDENT 0.0 .TP .B \-\-sslPEMKeyPassword= New in version 2.6. .sp Specifies the password to de\-crypt the certificate\-key file (i.e. \fI\%\-\-sslPEMKeyFile\fP). Use the \fI\%\-\-sslPEMKeyPassword\fP option only if the certificate\-key file is encrypted. In all cases, the \fBmongofiles\fP will redact the password from all logging and reporting output. .sp If the private key in the PEM file is encrypted and you do not specify the \fI\%\-\-sslPEMKeyPassword\fP option, the \fBmongofiles\fP will prompt for a passphrase. See ssl\-certificate\-password\&. .sp For more information about TLS/SSL and MongoDB, see /tutorial/configure\-ssl and /tutorial/configure\-ssl\-clients . .UNINDENT .INDENT 0.0 .TP .B \-\-sslCRLFile= New in version 2.6. .sp Specifies the \fB\&.pem\fP file that contains the Certificate Revocation List.

When using the \fBallowInvalidCertificates\fP setting, MongoDB logs as a warning the use of the invalid certificate. .sp Starting in MongoDB 4.0, if you specify \fB\-\-sslAllowInvalidCertificates\fP or \fBnet.ssl.allowInvalidCertificates: true\fP (or in MongoDB 4.2, the alias \fB\-\-tlsAllowInvalidateCertificates\fP or \fBnet.tls.allowInvalidCertificates: true\fP) when using x.509 authentication, an invalid certificate is only sufficient to establish a TLS/SSL connection but is \fIinsufficient\fP for authentication. .sp \fBWARNING:\fP .INDENT 7.0 .INDENT 3.5 Although available, avoid using the \fB\-\-sslAllowInvalidCertificates\fP option if possible. If the use of \fB\-\-sslAllowInvalidCertificates\fP is necessary, only use the option on systems where intrusion is not possible. .sp If the \fBmongo\fP shell (and other mongodb\-tools\-support\-ssl) runs with the \fB\-\-sslAllowInvalidCertificates\fP option, the \fBmongo\fP shell (and other mongodb\-tools\-support\-ssl) will not attempt to validate the server certificates. This creates a vulnerability to expired \fBmongod\fP and \fBmongos\fP certificates as well as to foreign processes posing as valid \fBmongod\fP or \fBmongos\fP instances. If you only need to disable the validation of the hostname in the TLS/SSL certificates, see \fB\-\-sslAllowInvalidHostnames\fP\&. .UNINDENT .UNINDENT .sp For more information about TLS/SSL and MongoDB, see /tutorial/configure\-ssl and /tutorial/configure\-ssl\-clients . .UNINDENT .INDENT 0.0 .TP .B \-\-sslAllowInvalidHostnames New in version 3.0. .sp Disables the validation of the hostnames in TLS/SSL certificates. Allows \fBmongofiles\fP to connect to MongoDB instances even if the hostname in their certificates do not match the specified hostname. .sp For more information about TLS/SSL and MongoDB, see /tutorial/configure\-ssl and /tutorial/configure\-ssl\-clients . .UNINDENT .INDENT 0.0 .TP .B \-\-username=, \-u= Specifies a username with which to authenticate to a MongoDB database that uses authentication.
