How would you find out the version of the kernel in /usr/src/linux?
A. cat /usr/src/linux/.version
B. cat /usr/src/linux/VERSION
C. Look in the README
D. head -4 /usr/src/linux/Makefile
Correct Answer: D
Explanation/Reference:
Explanation: The head command is used to display the first few lines of a file. The default is 10 lines but you can specify a number (in this case 4). The makefile is a script the tells the make utility how to build a program or programs (in this case, the kernel). Most makefiles contain comments at the top of the file which describe the program and version information.
