Final answer:
The command to display the operating system name is 'uname' on Unix-like systems and 'systeminfo' on Windows. 'uname -s' displays the kernel name, which is typically the operating system on Unix-like systems.
Step-by-step explanation:
The command used to display the operating system name varies depending on the operating system you are using. If you are using a Unix-like operating system, such as Linux or macOS, you can typically display the operating system name by using the uname command with the -a switch, which stands for all, to display all system information, or just uname to display the system name. For example, typing uname -s in the terminal would return the kernel name, which often implies the operating system on Unix-like systems. If you are using Windows, you can open the Command Prompt and type systeminfo to display detailed operating system information, including the name.
