Answer 1

a) Create a user (username= YOUR-FIRSTNAME).

Syntax= #useradd –m username

               #passwd username

               #usermod –a –G sudo username

               #cshs –s/bin/bash username

Code =

$ useradd -m YOUR_FIRSTNAME
$ passwd YOUR_FIRSTNAME
$ usermod -a -G sudo YOUR_FIRSTNAME
$ chsh -s bin/bash YOUR_FIRSTNAME

b) Create a file (filename=test) and use chmod command to add the write permission for Others.

Syntax= # touch file_name

# chmod g+w test.txt // + is used to give permission and w is used to write .

$ touch test.txt 
$ chmod g+w test.txt

c) Use setfacl to remove write permission to YOUR-FIRSTNAME user. Use getfacl to check the file's permissions.

Syntax= # setfacl -x u : username:w file

#getfacl file name

$ setfacl -x u:YOUR-FIRSTNAME:w file

$ getfacl test.txt

d) Remove YOUR-FIRSTNAME user.
