OBJECT := { nm | con | dev }
OPTIONS := {
-t[erse]

DESCRIPTIONnmcli is a command-line tool for controlling NetworkManager and getting
its status. It is not meant as a replacement of nm-applet or other
similar clients. Rather it's a complementary utility to these pro‐
grams. The main nmcli's usage is on servers, headless machines or just
for power users who prefer the command line.
The use cases comprise:
— Initscripts: ifup/ifdown can utilize NetworkManager via nmcli
instead of having to manage connections itself and possible inter‐
fere with NetworkManager.
— Servers, headless machines: No GUI is available; then nmcli is used
to talk directly to NetworkManager and control only system-wide
connections.
— User sessions: For this case, nmcli can talk to nm-applet to find
user connections. It can still talk directly to NetworkManager for
manipulating these connections. As nmcli doesn't have direct
access to user configuration data in GConf, nm-applet handles that
itself. That may, for example, cause the applet to pop up keyring
dialogs when secrets are needed.
OPTIONS
-t, --terse
Output is terse. This mode is designed and suitable for com‐
puter (script) processing.
-p, --pretty
Output is pretty. This causes nmcli to produce easy readable
outputs for humans, i.e. values are aligned, headers are
printed, etc.
-m, --mode tabular | multiline
Switch between tabular and multiline output. If omitted,
default is tabular for most commands. For the commands produc‐
ing more structured information, that cannot be displayed on a
single line, default is multiline. Currenly, they are:
'nmcli con list id|uuid <name>'
'nmcli dev list'
tabular - Output is a table where each line describes a single
entry. Columns define particular properties of the entry.
multiline - Each entry comprises more lines, each property on
its own line. The values are prefixed with the property name.
-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
--fields option.
all is used to print all valid field values of the command.
common is used to print common field values of the command. If
omitted, default is common. The option is mandatory when
--terse is used. In this case, generic values all and common
cannot be used. (This is to maintain compatibility when new
fields are added in the future).
-e, --escape yes | no
Whether to escape ':' and '\' characters in terse tabular mode.
The escape character is '\'. If omitted, default is yes.
-v, --version
Show nmcli version.
-h, --help
Print help information.
OBJECT
nm NetworkManager
Use this object to inquire and change state of NetworkManager.
COMMAND := { status | sleep | wakeup | wifi | wwan }
status
Show overall status of NetworkManager. This is the
default action, when no command is provided to nm object.
Reference to D-Bus:
No simple reference.
sleep
Put NetworkManager to sleeping mode. Thus all interfaces
that NetworkManager manages are deactivated.
Reference to D-Bus:
interface: org.freedesktop.NetworkManager
method: Sleep
arguments: TRUE
wakeup
Awake NetworkManager from sleep. When NetworkManager is
awaken, devices are available to be activated.
Reference to D-Bus:
interface: org.freedesktop.NetworkManager
method: Sleep
arguments: FALSE
wifi [on|off]
Inquire or set status of WiFi in NetworkManager. Without
any further argument, WiFi status is printed; on enables
WiFi; off disables WiFi.
Reference to D-Bus:
No simple reference.
wwan [on|off]
Inquire or set status of WWAN in NetworkManager. Without
any further argument, WWAN status is printed; on enables
WWAN; off disables WWAN.
Reference to D-Bus:
No simple reference.
con Connections
Get information about NetworkManager's connections.
COMMAND := { list | status | up | down }
list [id <id> | uuid <id> | system | user]
List configured connections. Without a parameter, con‐
figured connection from both system and user settings
services are listed. system argument filters only sys‐
tem-wide connections, user prints user connections only.
In order to get connection details, id with connection's
name or uuid with connection's UUID shall be specified.
When no command is given to con object, the default
action is 'nmcli con list'.
Reference to D-Bus:
No simple reference.
status
Print status of active connections.
Reference to D-Bus:
No simple reference.
up id <id> | uuid <id> [iface <iface>] [ap <hwaddr>] [--nowait]
[--timeout <timeout>]
Activate a connection. The connection is identified by
its name using id or UUID using uuid. For requiring par‐
ticular device to activate the connection on, iface
option with interface name should be given. ap option
can further concretize what AP should be used in case of
WiFi connection. --nowait option causes nmcli to exit
immediately and not to wait for command completion.
--timeout option provides a means to specify how long to
wait for operation completion.
Reference to D-Bus:
interface: org.freedesktop.NetworkManager
method: ActivateConnection
arguments: according to arguments
down id <id> | uuid <id>
Deactivate a connection. The connection is identified by
its name using id or UUID using uuid.
Reference to D-Bus:
interface: org.freedesktop.NetworkManager
method: DeactivateConnection
arguments: according to arguments
dev Devices
Get information about devices.
COMMAND := { status | list | disconnect | wifi }
status
Print status of devices. This is the default action,
when no command is specified to dev object.
Reference to D-Bus:
No simple reference.
list [iface <iface>]
Get detailed information about devices. Without an argu‐
ment, all devices are examined. To get information for a
specific device, iface argument with the interface name
should be provided.
Reference to D-Bus:
No simple reference.
disconnect iface <iface> [--nowait] [--timeout <timeout>]
Disconnect a device and prevent the device from automati‐
cally activating further connections without user/manual
intervention. --nowait option causes nmcli to exit imme‐
diately and not to wait for command completion. --time‐
out option provides a means to specify how long to wait
for operation completion.
Reference to D-Bus:
interface: org.freedesktop.NetworkManager.Device
method: Disconnect
arguments: none
wifi [list [iface <iface>] [hwaddr <hwaddr>]]
List available WiFi access points. iface and hwaddr
options can be used to get just APs for particular inter‐
face or specific AP, respectively.
Reference to D-Bus:
No simple reference.
