What type of information does the 'uname' command display?

The 'uname' command is a fundamental utility in Linux used primarily to display system information. When executed, it typically returns details about the operating system's kernel, including its name and version. This command can be particularly useful for system administrators and users who need to understand the specifics of the current kernel in use, which can affect compatibility with software and hardware, as well as security features and system capabilities.

Using 'uname' without any options gives a concise output of the kernel name (e.g., "Linux") and can be further customized with flags to provide additional details, such as the machine name, release number, and processor architecture. This capability makes it a crucial tool in system monitoring and troubleshooting, allowing for swift identification of the kernel environment in which operations are being performed.

File system information, disk usage, and network settings pertain to different commands and tools within Linux, such as 'df' for disk usage and 'ifconfig' or 'ip' for network configurations. Therefore, focusing on kernel specifics is where 'uname' distinctly excels, making the understanding of kernel attributes its primary function.
