POS 433 Week 1 UNIX and Linux Comparison Matrix NEW

Name three versions of Linux
1.  Red Hat Enterprise Linux
2.  Suse Linux Enterprise Server
3.  Ubuntu

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.

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.

Use the command to change directory locations.
a. cd
b. rm
c. mkdir
d. cut
A: cd

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.

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’.

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.

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.

The command that deletes a file.
a. rmdir
b. cd
c. rm
d. pwd
C: The only one that is for file removal.

The command displays your present working directory.
a. cat
b. cd
c. touch
d. pwd
D: pwd.

The system directory contains the Linux kernel.
a. /boot
b. /root
c. /dev
d. /var
A: /boot, generally.

The in the vi editor allows you to save and quit the program.
a. :wq
b. q!
c. w!
d. !
A: write then quit.

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.

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.
