Question

JUST NEED THE COMMANDS (Using terminal in Linux)

Professor Karam is preparing his teaching materials for the new semester. He needs to reorganize the directories and files a bit. Please help him to complete the following tasks in the command line environment. Use the “script” command to record the whole session input/output to a file named “it4423-(your email id).txt”. Note: practice and write down the process first and make sure you don’t make any mistake during the recording process.

a) Figure 1 shows the current directory structure. Rectangular boxes are directories and ovals are text files. Create a directory structure as shown in Figure 1 in your personal or home folder (directory) as a starting point.

b) Perform a serial of file and directory operations to arrive a structure as shown in Figure 2. Use the most efficient commands (as few as possible) to accomplish this – hint: do not use too many “cd” commands.

c) After you have finished, list all files and sub-directories (at all levels) in the “IT4423-(your id)” directory using one command. Take a screenshot of your desktop with the terminal open – the result should be clearly seen. Verify the structure is the same as in Figure 2.

Note:

- File “Test1” is renamed to “Midterm”; “Final” is a another copy of “Test1”

- File “plan” and “lab” are the same in “Week1” and “Week2”.

- File “Syllabus-template” is a copy of “Syllabus”.

- File “Syllabus” in “Week1” is a link to “Syllabus” in “Fall 2012”

- The top level directory name should be “IT4423-(your email id)” (“jzheng” is an example id) Make other reasonable assumptions if necessary. But clearly state your assumptions in the document.

Explanation / Answer

Here is a series of commands(for linux terminal):

Note:
commands and their meanings-
mkdir- Make directory
cd- change directory
mv- move
cp- copy
ln- link
Type commands one by one as given below

1. For Orignal Structure:

Open terminal
By default you should be in your home directory

$ mkdir IT4423
$ cd IT4423
$ touch Syllabus.txt
$ cd ..
$ mkdir Fall2011
$ cd Fall2011
$ mkdir Exams
$ cd Exams
$ touch guide.txt
$ touch test1.txt
$ mkdir Library
$ cd ..
$ cd ..
$ mkdir Lectures
$ cd Lectures
$ mkdir Week1
$ cd Week1
$ touch plan.txt
$ touch lab.txt
$ cd /home/IT4423
$ mkdir Spring2011
$ cd Spring2011
$ mkdir Exams
$ cd Exams
$ touch Test1.txt

2.For Finished structure

$ mkdir IT4423-jzeng
$ cp /home/IT4423/* /home/IT4423-jzheng
$ mv Syllabus.txt Syllabus-template.txt
$ mv Fall2011 Fall2012
$ cd Fall2012
$ touch Syllabus
$ cd Library
$ cp /home/IT4423-jzheng/Fall2011/Exams/Test1.txt /home/IT4423-jzheng/Fall2012/Exams/Library/Midterm.txt
$ cp /home/IT4423-jzheng/Fall2011/Exams/Test1.txt /home/IT4423-jzheng/Fall2012/Exams/Library/Final.txt
$ cd /home/IT4423-jzheng/Fall2012/Lectures/Week1
$ touch Syllabus.txt
$ ln -s Syllabus.txt /home/IT4423-jzheng/Fall2012/Syllabus.txt
$ touch plan.txt
$ touch lab.txt
$ cd ..
$ mkdir Week2
$ touch plan.txt
$ cp /home/IT4423-jzheng/Fall2012/Lectures/Week1/plan.txt /home/IT4423-jzheng/Fall2012/Lectures/Week2/plan.txt
$ touch lab.txt
$ cp /home/IT4423-jzheng/Fall2012/Lectures/Week1/lab.txt /home/IT4423-jzheng/Fall2012/Lectures/Week2/lab.txt

To list of directories and files in tree :
Firstly install tree

$ yum install tree
$ sudo apt-get install tree

and then for orignal structure:
$ tree /home/IT4423
for final structure:
$ tree /home/IT4423-jzheng
