Users running on macOS Sierra require the 3.2.10 or newer version
of  mongofiles\&.
.UNINDENT
.UNINDENT
.SH SYNOPSIS
.sp
The \fI\%mongofiles\fP 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.
.sp
All \fI\%mongofiles\fP commands have the following form:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
mongofiles <options> <commands> <filename>
.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 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.

.B \-\-sslCAFile <filename>
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\&.

\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.

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

.B \-\-sslAllowInvalidCertificates
New in version 2.6.

.sp
Bypasses the validation checks for server certificates and allows
the use of invalid certificates. 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
# We created a separate blurb for tls in the ssl\-clients page.
.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\&.
