Assume the following directory structures in your home directory: • /home/(username)/ — use your own (home directory) • /home/(username) /Dir1.0/Dir1.1/ • /home/(username) /Dir2.0/Dir2.1/ in your home directory, create directories Dir1.0 & Dir 2.0, then create directories Dirl.1 & Dir2.1 inside other directories according to above.

[1 pt] • In your home directory and copy file4 to Dir2.0 with a new name file3. [1 pt] • Concatenate files and file4 to a new file named CatFile and save to home directory [1 pt) • Change to home directory with single command (from anywhere). [0.5 pts]

Answer 1

Question a) Unix/Linux admin account user name is root

   and it's home directory is /home

Question b) Assumed home directory is /home/HomeworkLibuser

$pwd

/home/HomeworkLibuser

$mkdir    Dir1.0

$mkdir    Dir2.0

The above two commands creates two directories

with the names Dir1.0 and Dir2.0 under HomeworkLibuser

home directory i.e /home/HomeworkLibuser

Now to create a subdirectory Dir1.1 under Dir1.0

First we need to change Dir1.0

For this we have to use cd command and its argument as Dir1.0

$cd   Dir1.0

$pwd

/home/HomeworkLibuser/Dir1.0

pwd is a command to know the present or current working directory. now we are under Dir1.0

Here we need to create Dir1.1.

For this we have to use mkdir command with a subdirectory name as Dir1.1

$mkdir     Dir1.1

Now we need to create Dir2.1 subdirectory under Dir2.0

But, we are in Dir1.0 directory

So, First we need to goback to the home directory

i.e /home/HomeworkLibuser

For this we need use cd command with two consecutive dots as arugment ( .. -- means parent directory )

$cd ..

$pwd

/home/HomeworkLibuser

Now change to Dir2.0 using again cd command with arguments as Dir2.0

$cd    Dir2.0

$pwd

/home/HomeworkLibuser/Dir2.0

Now we are under Dir2.0.

mkdir and its argument as Dir2.1, creates a Dir2.1 subdirectory.

$mkdir   Dir2.1

cd ..

$pwd

/home/HomeworkLibuser

Question C)

$pwd

/home/HomeworkLibuser

$cd    Dir1.0

$pwd

/home/HomeworkLibuser/Dir1.0

$   >     file1 # this command simply creates a zero byte file

$ls

Dir1.1     file1

C.1)Change to Dir1.0 and move file1 to Dir2.1 with new name file4.

$mv   file1      ../Dir2.0/Dir2.1/file4

$cat   file1

cat: file1: No such file or directory

$

Means, file1 was moved to

..                  -- parent directory   i.e /home/HomeworkLibuser

../Dir2.0           -- i.e /home/HomeworkLibuser/Dir2.0

../Dir2.0/dir2.1   -- i.e /home/HomeworkLibuser/Dir2.0/Dir2.1

file4                  --    is the new name of the oldfile file1 which is from /home/HomeworkLibuser/Dir1.0

C.2) In your home directory and copy file4 to Dir2.0 with a new name file3

$cd ~ # ~ (tild symbol) directly takes to the users home directory

$pwd

/home/HomeworkLibuser

$

$cp   Dir2.0/Dir2.1/file4      Dir2.0/file3

$

C.3) concatenate file3 and file4 to a new file named CatFile and save to home directory

$pwd

/home/HomeworkLibuser

$cat Dir2.0/file3    Dir2.0/Dir2.1/file4    >     /home/HomeworkLibuser/CatFile

$cat CatFile

$

Nothing will be displayed because,intially we create a zero byte file

C.4) Change to home directory with sing command ( from anywhere )

~ ( tlid symbol).

It is a metacharacter, it represents home directory.

$cd ~

$pwd

/home/HomeworkLibuser
