Red Hat Enterprise Linux 2. Suse Linux Enterprise Server 3. Ubuntu 3.Describe 3 major differences between Unix and Linux 1. Licensing; Linux is all GPL, while UNIX varied between commercial and BSD license
2. Users: Linux originally developed for home users while UNIX was developed for servers. 3. Filesystem: Standard FS on Linux is EXT(3/4) while varies on UNIX from JFS2 to UFS2 to ZFS. 4. Linux, technically, is not an OS, UNIX is. Linux is a kernel, surrounded by packages. 4.Which of the following is not a UNIX or Linux variant a. SunOS b. RedHat c. DOS d. HP-UX e. Debian Technically I think you want C: DOS, though I would argue that DOS is a ripoff of CP/M which itself was very much akin to UNIX. 5.Use the command to change directory locations. a. cd b. rm c. mkdir d. cut A: cd
6.Use the command to delete a directory. a. delete_dir b. mkdir c. rmdir d. cat C: rmdir, though this will only work if the directories are empty. Rm – rfdir works otherwise. 7.Which of the following are text editors? (Choose all that apply.) a. vi b. emacs c. ls d. cat A and B : Though why anyone would choose emacs over vi is beyond me. ls lists dirs., and cat displays a file, but you specified „editor‟. 8.The command creates a directory named winchester in the root directory. a. mkdir /winchester b. mkdir ../Winchester c. mkdir \winchester
d. md /Winchester A. / specifies root, and UNIX is case sensitive. 9.The command allows you to change directory locations to a child directory named child1. a. mkdir ƒ child1 b. cdƒ ../ child1 c. cd child1 d. cdƒ / C:. Obviously. 10. The command that deletes a file. a. rmdir b. cd c. rm d. pwd C: The only one that is for file removal. 11. The command displays your present working directory. a. cat b. cd
c. touch d. pwd D: pwd. 12. The system directory contains the Linux kernel. a. /boot b. /root c. /dev d. /var A: /boot, generally. 13. The in the vi editor allows you to save and quit the program. a. :wq b. q! c. w! d. ! A: write then quit. 14. The command to rename a file is . a. mv b. cp
c. del d. rename A: mv and D: rename which has been available since 2000. 15. The command to make a duplicate of a file. a. mv b. cp c. del d. rename B: cp, for copy. 16. In vi, the command to change to insert mode is: a. o b. O c. i d. d C: i. which inputs text before the cursor and B: O works as well to insert a newline before current line, and A: o for newline after current line. 17. In vi, the command to remove a character is: a. o
b. O c. i d. x D: x. ============================================== POS 433 Week 1 UNIX® and Linux® Comparison Matrix For more course tutorials visit www.tutorialrank.com Tutorial Purchased: 4 Times, Rating: A+ POS 433 Week 1 UNIX® and Linux® Comparison Matrix Instructions Assignment Preparation: Activities include completing the SkillSoft course, independent student reading, and research.
