Understanding uname

uname stands for "Unix name," and it's a powerful command that retrieves various system-related information. To get the version information, simply use:

• uname -s: Prints the operating system name (usually "Linux").
• uname -n: Shows the network node hostname.
• uname -m: Displays the hardware architecture (e.g., x86_64).
• uname -o: Outputs the operating system type (e.g., GNU/Linux).
