nmcli-general:tldr:df182
This command is used to change the hostname of a device using the "nmcli" command-line tool with superuser (root) privileges. Here's a breakdown of the command:
-
"sudo": It stands for "superuser do" and it allows the command to be executed with administrative rights. It is typically used to perform tasks that require elevated permissions.
-
"nmcli": It is a command-line tool for managing NetworkManager, a software utility used for configuring network connections on Linux-based systems.
-
"general": It specifies the general settings of NetworkManager.
-
"hostname": It is an option that allows you to get or set the hostname of the device.
-
"${new_hostname}": It is a placeholder variable that represents the desired new hostname for the device. You need to replace "${new_hostname}" with the actual desired hostname when using the command.
By running this command with appropriate privileges and providing the desired new hostname, you can change the hostname of the device.
