What does the command 'nmcli con up' accomplish?

The command 'nmcli con up' is used to bring up a specified network connection in NetworkManager, which is a powerful tool for managing network connections in Linux environments. When executed, it activates the connection profile that you specify, effectively enabling the network interface associated with that connection. This action establishes the connection to the network, allowing the system to send and receive data through it.

For example, if you have a connection profile named "Home WiFi," running 'nmcli con up Home WiFi' would initiate the connection process for that profile, connecting your system to the network it represents. This command is particularly useful when you want to activate a connection without needing to interact with graphical user interfaces, enabling automation and script-based network management.

Creating a new network connection, displaying the status of connections, or removing a connection are distinct actions that require different commands and do not relate to the function of 'nmcli con up'.
