nmcli is a command-line tool for controlling NetworkManager and reporting network status. It can be utilized as a replacement for nm-applet or other graphical clients. nmcli is used to create, display, edit, delete, activate, and deactivate network connections, as well as control and display network device status. See nmcli-examples(7) for ready to run nmcli examples.\n Typical uses include:\n \u00b7 Scripts: Utilize NetworkManager via nmcli instead of managing network connections manually. nmcli 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. \n \u00b7 Servers, headless machines, and terminals: nmcli can be used to control NetworkManager without a GUI, including creating,editing, starting and stopping network connections and viewing network status.<\/code><\/pre>\n\n\n\n<\/span>\u9009\u9879[OPTIONS]<\/span><\/h2>\n\n\n\n-a | --ask<\/h3>\n\n\n\n

-a | --ask\n When using this option nmcli will stop and ask for any missing required arguments, so do not use this option for non-interactive purposes like scripts.

-c | --colors {yes | no | auto}\n This option controls color output (using terminal escape sequences). yes enables colors, no disables them, auto only produces colors when standard output is directed to a terminal. The default value is auto.\n The actual colors used are configured as described in terminal-colors.d(5). Please refer to the COLORS section for a list of color names supported by nmcli.\n If the environment variable NO_COLOR is set (to any value), then coloring is disabled with mode \"auto\". Explicitly enabling coloring overrides the environment variable.<\/code><\/pre>\n\n\n\n\u6837\u4f8b\u3002\u5f53\u53c2\u6570\u4e3ano\u65f6\uff0c\u4e00\u4e9b\u5173\u952e\u53c2\u6570\u72b6\u6001\u6ca1\u6709\u4e86\u7279\u6b8a\u989c\u8272\u663e\u793a\u3002<\/p>\n\n\n\n![\"\"](\"https:\/\/www.gbase8.cn\/wp-content\/uploads\/2021\/04\/image-19.png\")

--complete-args\n Instead of conducting the desired action, nmcli will list possible completions for the last argument.

Get and change system hostname. With no arguments, this prints currently configured hostname. When you pass a hostname, it will be handed over to NetworkManager to be set as a new system hostname.\n\n Note that the term \"system\" hostname may also be referred to as \"persistent\" or \"static\" by other programs or tools. The hostname is stored in \/etc\/hostname file in most distributions. For example, systemd-hostnamed service uses the term \"static\" hostname and it only reads the \/etc\/hostname file when it starts.<\/code><\/pre>\n\n\n\n\u6837\u4f8b<\/p>\n\n\n\n
