.SH DESCRIPTION
.B nmcli
is a command-line tool for controlling NetworkManager and reporting on its status.
It is not meant as a full replacement for \fInm-applet\fP or other similar clients
but as a complementary utility to those programs.
The main usage for \fInmcli\fP is on servers, headless machines or for power users
who prefer the command line.
.P
Typical applications include:
.IP \(em 4
Initscripts: ifup/ifdown can utilize NetworkManager via \fInmcli\fP instead of
having to manage connections itself and possibly interfere with NetworkManager.
.IP \(em 4
Servers, headless machines: No GUI is available; then \fInmcli\fP can be used
to activate/deactivate connections.  However, if a connection requires a secret
in order to activate and if that secret is not stored at the system level,
\fInmcli\fP will not be able to activate it; it is currently unable to supply
the secrets to NetworkManager.
.IP \(em 4
User sessions: \fInmcli\fP can be used to activate/deactivate connections from
the command line, but a client with a secret agent (like \fInm-applet\fP) is needed
for supplying secrets not stored at the system level. Keyring dialogs and
password prompts may appear if this happens.
.SS \fIOPTIONS\fP
.TP
.B \-t, \-\-terse
Output is terse.  This mode is designed and suitable for computer (script)
processing.
.TP
.B \-p, \-\-pretty
Output is pretty. This causes \fInmcli\fP to produce easily readable outputs
for humans, i.e. values are aligned, headers are printed, etc.
.TP
.B \-m, \-\-mode tabular | multiline
Switch between \fItabular\fP and \fImultiline\fP output.
If omitted, default is \fItabular\fP for most commands. For the commands
producing more structured information, that cannot be displayed on a single
line, default is \fImultiline\fP. Currenly, they are:
.br
.nf
  'nmcli con list id|uuid <name>'
  'nmcli dev list'
.fi
\fItabular\fP   - Output is a table where each line describes a single entry.
Columns define particular properties of the entry.
.br
\fImultiline\fP - Each entry comprises multiple lines, each property on its own
line. The values are prefixed with the property name.
.TP
.B \-f, \-\-fields <field1,field2,...> | all | common
This option is used to specify what fields (column names) should be printed.
Valid field names differ for specific commands. List available fields by
providing an invalid value to the \fI--fields\fP option.
.br
\fIall\fP is used to print all valid field values of the command.
\fIcommon\fP is used to print common field values of the command.
If omitted, default is \fIcommon\fP.
The option is mandatory when \fI--terse\fP is used.  In this case, generic
values \fIall\fP and \fIcommon\fP cannot be used.  (This is to maintain
compatibility when new fields are added in the future).
.TP
.B \-e, \-\-escape yes | no
Whether to escape ':' and '\\' characters in terse tabular mode.  The escape
character is '\\'.
If omitted, default is \fIyes\fP.
.TP
.B \-v, \-\-version
Show \fInmcli\fP version.
.TP
.B \-h, \-\-help
Print help information.
.SS \fIOBJECT\fP
.TP
.B nm

by NetworkManager are deactivated when it falls asleep. This command is not
meant for user to enable/disable networking, use \fIenable\fP for that. D-Bus
\fISleep\fP method is designed to put NetworkManager to sleep or awake for
suspending/resuming the computer.

Wi-Fi status is printed; \fIon\fP enables Wi-Fi; \fIoff\fP disables Wi-Fi.
.br
.nf
\fBReference to D-Bus:\fP

installations.

.sp
.RS
.TP
.B list [id <id> | uuid <id>]
.br
List configured connections.  Without a parameter, all connections
are listed.  In order to get connection details, \fIid\fP with connection's
name or \fIuuid\fP with connection's UUID shall be specified.  When no command
is given to the \fIcon\fP object, the default action is 'nmcli con list'.

.br
Activate a connection.  The connection is identified by its name using \fIid\fP
or UUID using \fIuuid\fP. When requiring a particular device to activate the
connection on, the \fIiface\fP option with interface name should be given.
The \fIap\fP option can further specify what AP should be used in case of a Wi-Fi
connection. The \fI\-\-nowait\fP option causes \fInmcli\fP to exit immediately and
not to wait for command completion. The \fI\-\-timeout\fP option provides a means
to specify how long to wait for operation completion.

No simple reference.
.fi
.TP
.B list [iface <iface>]
.br
Get detailed information about devices.  Without an argument, all devices are
examined. To get information for a specific device, the \fIiface\fP argument
with the interface name should be provided.
.br
.nf
\fBReference to D-Bus:\fP
No simple reference.
.fi
.TP
.B disconnect iface <iface> [\-\-nowait] [\-\-timeout <timeout>]
.br
Disconnect a device and prevent the device from automatically activating further
connections without user/manual intervention. The \fI\-\-nowait\fP option causes
\fInmcli\fP to exit immediately and not to wait for command completion.
The \fI\-\-timeout\fP option provides a means to specify how long to wait for
operation completion.

List available Wi-Fi access points. The \fIiface\fP and \fIbssid\fP options
can be used to list APs for a particular interface or with a specific BSSID,
respectively.

.TP
.B wifi connect <(B)SSID> [password <password>] [wep-key-type key|phrase] [iface <iface>] [bssid <BSSID>] [name <name>] [--private] [--nowait] [--timeout <timeout>]
.br
Connect to a Wi-Fi network specified by SSID or BSSID. The command creates a new
connection and then activates it on a device. This is a command-line counterpart
of clicking an SSID in a GUI client. The command always creates a new connection
and thus it is mainly useful for connecting to new Wi-Fi networks. If a connection
for the network already exists, it's better to connect through it using 
\fInmcli con up id <name>\fP. Note that only open, WEP and WPA-PSK networks are
supported at the moment. It is also supposed that IP configuration is obtained via
DHCP.
.RS
.PP
Available options are:
.IP \fIpassword\fP 13
- password for secured networks (WEP or WPA)
.IP \fIwep-key-type\fP 13
- type of WEP secret, either \fIkey\fP for ASCII/HEX key or \fIphrase\fP for passphrase
.IP \fIiface\fP 13
- interface that will be used for activation
.IP \fIbssid\fP 13
- if specified, the created connection will be restricted just for the BSSID
.IP \fIname\fP 13
- if specified, the connection will use the name (else NM creates a name itself)
.IP \fI\-\-private\fP 13
- the connection will only be visible to the user who created it (else the connection is system-wide)
.IP \fI\-\-nowait\fP 13
- exit immediately without waiting for command completion
.IP \fI\-\-timeout\fP 13
- how long to wait for command completion (default is 90 s)

.SH ENVIRONMENT VARIABLES
\fInmcli\fP's behavior is affected by the following environment variables.
.IP "LC_ALL" 13
If set to a non-empty string value, it overrides the values of all the other
internationalization variables.
.IP "LC_MESSAGES" 13
Determines the locale to be used for internationalised messages.
.IP "LANG" 13
Provides a default value for the internationalization variables that are unset
or null.

.RE
Notes about localization:
.br
Be aware that \fInmcli\fP is localized and that's why the output depends on
your environment. It's important to realize that especially when you parse the
output.
.br
Call \fInmcli\fP as \fBLC_ALL=C nmcli\fP to be sure the locale is
set to "C" while executing in a script.

\fBLC_ALL\fP, \fBLC_MESSAGES\fP, \fBLANG\fP variables specify the LC_MESSAGES
locale category (in that order), which determines the language that \fInmcli\fP
uses for messages.  The "C" locale is used if none of these variables are set,
and this locale uses English messages.

.SH EXIT STATUS
\fInmcli\fP exits with status 0 if it succeeds, a value greater than 0 is
returned if an error occurs.
.IP "0" 4
Success - indicates the operation succeeded
.IP "1" 4
Unknown or unspecified error
.IP "2" 4
Invalid user input, wrong \fInmcli\fP invocation
.IP "3" 4
Timeout expired (see commands with \fI\-\-timeout\fP option)
.IP "4" 4
Connection activation failed
.IP "5" 4
Connection deactivation failed
.IP "6" 4
Disconnecting device failed
