This is Lunix command. Just need help with command line. I will run the command line on my virtualbox to get the answers

6. What is the code name for this version of Ubuntu? Examine /etc/os-release.

7. Which directories are listed in /home/? Why is that listed?

8. What is the first directory in your PATH?

9. What is wrong with the setting in the previous question?

10. Run the command uname and, using the right options, report the kernel release. (You may want to do uname --help here since the man page does not seem to show the option.)

11. What version of uname is currently installed on the machine and who was it written by?

12. Using /proc/partitions tell me how many blocks are in /dev/sda.

13. What are the major/minor numbers for /dev/sda?

14. Why do sda, sda1, sda2, and all have the same major number but different minor numbers?

15. Try to edit the /etc/shadow file (using nano), are you able to? Why or why not?

16. What is your user number and what is your group number?

17. What is the filesystem type for /dev/sda1?

18. What is /dev/cdrom? What are the major/minor numbers for the actual device?

19. What is the PID for rcu_sched? How did you find this out?

20. Id like to know information on my available memory. What command will tell you this, and what is the total memory it reports on?

21. How many files end in .h in the /usr/include directory (only, not subdirectories)? Tell me the number and the command you used.

22. Tell me the setting for root in /etc/sudoers. Youll have to figure out how to actually look at the file since you do not have permission.

23. Attempt to update and then upgrade the virtual machine. Provide the commands to do both. (This may take several minutes. The remaining questions require that the update/upgrade is completed.)

24. Using the df command with the appropriate options, determine the number of inodes allocated for /dev/sda1. Compare this with the previous number from the beginning of the assignment.
