Which Linux command is used to display the current version of the kernel?

Correct option is D

The uname -r command in Linux displays the current version of the kernel that the system is running. The uname command provides system information, and the -r flag specifically shows the kernel version.
Important Key Points:
1. The Linux kernel version is crucial for identifying system compatibility and updates.
2. uname is a standard Linux utility for fetching basic system details like kernel name, version, and architecture.
3. Other related uname options include:
· uname -a: Displays all system information.
· uname -n: Shows the system’s hostname.
· uname -m: Displays the system architecture (e.g., x86_64).
Knowledge Booster:
· kernel -v: This is not a valid Linux command. The -v flag in uname displays the kernel version with additional build details, but it doesn’t exist as kernel -v.
· version: Not a valid command in Linux to fetch kernel details.
· lskernel: This is a fictional command and not part of Linux utilities.
· kerninfo: Similarly, this is not a valid Linux command.
