  • Perform administrative tasks with ease

How to Use the 'hostname' Command?

Using the 'hostname' command is straightforward. Here are some examples:

Displaying the Host Name

Setting the Host Name

To set or change the host name of your system, you need to use the 'hostname' command followed by the new host name. For example, to change the host name to 'newhost', you would type:

$ hostname newhost

Remember, you need to have administrative privileges to change the host name.
