Usage: nmcli connection modify { ARGUMENTS | help }

ARGUMENTS := [id | uuid | path] <ID> ([+|-]<setting>.<property> <value>)+

Modify one or more properties of the connection profile.
The profile is identified by its name, UUID or D-Bus path. For multi-valued
properties you can use optional '+' or '-' prefix to the property name.
The '+' sign allows appending items instead of overwriting the whole value.
The '-' sign allows removing selected items instead of the whole value.

Examples:
nmcli con mod home-wifi wifi.ssid rakosnicek
nmcli con mod em1-1 ipv4.method manual ipv4.addr "192.168.1.2/24, 10.10.1.5/8"
nmcli con mod em1-1 +ipv4.dns 8.8.4.4
nmcli con mod em1-1 -ipv4.dns 1
nmcli con mod em1-1 -ipv6.addr "abbe::cafe/56"
nmcli con mod bond0 +bond.options mii=500
nmcli con mod bond0 -bond.options downdelay

Usage: nmcli connection clone { ARGUMENTS | help }

ARGUMENTS := [--temporary] [id | uuid | path] <ID> <new name>

Clone an existing connection profile. The newly created connection will be
the exact copy of the <ID>, except the uuid property (will be generated) and
id (provided as <new name> argument).

46.

Usage: nmcli connection edit { ARGUMENTS | help }

ARGUMENTS := [id | uuid | path] <ID>

Edit an existing connection profile in an interactive editor.
The profile is identified by its name, UUID or D-Bus path

ARGUMENTS := [type <new connection type>] [con-name <new connection name>]

Add a new connection profile in an interactive editor.

47.

Usage: nmcli connection delete { ARGUMENTS | help }

ARGUMENTS := [id | uuid | path] <ID>

Delete a connection profile.
The profile is identified by its name, UUID or D-Bus path.

48.

Usage: nmcli connection monitor { ARGUMENTS | help }

ARGUMENTS := [id | uuid | path] <ID> ...

Monitor connection profile activity.
This command prints a line whenever the specified connection changes.
Monitors all connection profiles in case none is specified.

49.

Usage: nmcli connection reload { help }

Reload all connection files from disk.

50.

Usage: nmcli connection load { ARGUMENTS | help }

ARGUMENTS := <filename> [<filename>...]

Load/reload one or more connection files from disk. Use this after manually

state.

51.

Usage: nmcli connection import { ARGUMENTS | help }

ARGUMENTS := [--temporary] type <type> file <file to import>
