<refsect1 id='description'><title>Description</title>
<para><command>nmcli</command> is a command-line tool for controlling
NetworkManager and reporting network status. It can be utilized as a
replacement for <command>nm-applet</command> or other graphical clients.
<command>nmcli</command> is used to create, display, edit, delete, activate,
and deactivate network connections, as well as control and display network
device status. See
<link linkend='nmcli-examples'><citerefentry><refentrytitle>nmcli-examples</refentrytitle><manvolnum>7</manvolnum></citerefentry></link>
for ready to run nmcli examples.</para>
<para>Typical uses include:</para>
<itemizedlist>
<listitem>
<para>Scripts: Utilize NetworkManager via <command>nmcli</command> instead of
managing network connections manually. <command>nmcli</command> supports a
terse output format which is better suited for script processing. Note that
NetworkManager can also execute scripts, called "dispatcher scripts", in
response to network events. See
<link linkend='NetworkManager'><link linkend='NetworkManager'><citerefentry><refentrytitle>NetworkManager</refentrytitle><manvolnum>8</manvolnum></citerefentry></link></link>
for details about these dispatcher scripts.</para>
</listitem>
<listitem>
<para>Servers, headless machines, and terminals: <command>nmcli</command> can
be used to control NetworkManager without a GUI, including creating, editing,
starting and stopping network connections and viewing network status.</para>

<listitem>
<para>When using this option <command>nmcli</command> will stop and ask for any

<listitem>
<para>This option controls color output (using terminal escape sequences).
<literal>yes</literal> enables colors, <literal>no</literal> disables them,
<literal>auto</literal> only produces colors when standard output is directed
to a terminal. The default value is <literal>auto</literal>.</para>
<para>The actual colors used are configured as described in

Please refer to the <link linkend='colors' endterm='colors.title' /> section for a
list of color names supported by <command>nmcli</command>.</para>
<para>If the environment variable <literal>NO_COLOR</literal> is set (to any non-empty value),
then coloring is disabled with mode "auto". If the environment variable <literal>CLICOLOR_FORCE</literal>
is set (to any non-empty value), then coloring is enabled with mode "auto". Explicitly enabling coloring overrides
the environment variable.</para>

Reload NetworkManager's configuration and perform certain

access via PolicyKit and contrary to signals it is
synchronous. Available flags are:
</para>
<variablelist>

<term><option>conf</option></term>

Reload the NetworkManager.conf configuration from
disk. Note that this does not include connections, which
can be reloaded through <command>nmcli connection
reload</command> instead.
</para></listitem>
</varlistentry>
<varlistentry>
<term><option>dns-rc</option></term>
<listitem><para>
Update DNS configuration, which usually involves writing
/etc/resolv.conf anew. This is equivalent to sending the
SIGUSR1 signal to the NetworkManager process.
</para></listitem>
</varlistentry>
<varlistentry>
<term><option>dns-full</option></term>
<listitem><para>
Restart the DNS plugin. This is for example useful when
using dnsmasq plugin, which uses additional

you edit those files, you can restart the DNS
plugin. This action shortly interrupts name resolution.

With no flags, everything that is supported is reloaded,
which is identical to sending a SIGHUP. See

<para>NetworkManager stores all network configuration as "connections",
which are collections of data (Layer2 details, IP addressing, etc.) that
describe how to create or connect to a network. A connection is "active"
when a device uses that connection's configuration to create or connect to
a network. There may be multiple connections that apply to a device, but only
one of them can be active on that device at any given time. The additional
connections can be used to allow quick switching between different networks
and configurations.</para>
<para>Consider a machine which is usually connected to a DHCP-enabled network,
but sometimes connected to a testing network which uses static IP addressing.
Instead of manually reconfiguring eth0 each time the network is changed, the
settings can be saved as two connections which both apply to eth0, one for DHCP
(called <literal>default</literal>) and one with the static addressing details (called
<literal>testing</literal>). When connected to the DHCP-enabled network the user would run
<command>nmcli con up default</command> , and when connected to the static network the user
would run <command>nmcli con up testing</command>.</para>

the active profiles are shown.</para>
<para>The <option>--order</option> option can be used to get custom
ordering of connections. The connections can be ordered by active status
(<literal>active</literal>), name (<literal>name</literal>), type
(<literal>type</literal>) or D-Bus path (<literal>path</literal>). If
connections are equal according to a sort order category, an additional
category can be specified. The default sorting order is equivalent to
<literal>--order active:name:path</literal>. <literal>+</literal> or no
prefix means sorting in ascending order (alphabetically or in numbers),
<literal>-</literal> means reverse (descending) order. The category names

<para>some networks may require credentials during activation. You can give

password in the form:
<programlisting>setting_name.property_name:the password</programlisting>
For example, for WPA Wi-Fi with PSK, the line would be
<programlisting>802-11-wireless-security.psk:secret12345</programlisting>
For 802.1X password, the line would be
<programlisting>802-1x.password:my 1X password</programlisting>
<command>nmcli</command> also accepts <literal>wifi-sec</literal> and <literal>wifi</literal> strings instead of
<literal>802-11-wireless-security</literal>. When NetworkManager requires a password and it is
not given, <command>nmcli</command> will ask for it when run with <option>--ask</option>.
If <option>--ask</option> was not passed, NetworkManager can ask another secret

<para>If you want to append an item or a flag to the existing value, use

For certain properties you can also remove elements by specifying the zero-based
index(es).
The <literal>+</literal> and <literal>-</literal> modifiers
only have a real effect for properties that support them.
These are for example multi-value (container) properties or flags like <literal>ipv4.dns</literal>,
