The “uname -s” command is used to print the kernel name of the operating system. When you run this command in a terminal or command prompt, it will output the kernel name.
For example, on a Linux system, running “uname -s” would display “Linux” as the output. On other operating systems, such as macOS, the output would be “Darwin,” and on Windows, it would be “Windows_NT.”
The “uname -s” command is commonly used in scripts or for diagnostic purposes to identify the kernel name of the operating system running on a particular system.
