Answer 1

SOLUTION

The following have been implemented on Ubuntu Linux.

Section IV: Create the following users and groups.

For this solution we have to create the necessary groups first, using the following commands.

groupadd Finance

groupadd Accountant

groupadd HumanResources

groupadd IT

groupadd Developer

= root@ubuntu: - root@ubuntu:~# groupadd Finance root@ubuntu:-# groupadd Accoutant root@ubuntu:-# groupadd HumanResources root@ubuntu:-# groupadd IT root@ubuntu:-# groupadd Developer root@ubuntu:-# groupadd Admin root@ubuntu:-# OO

The next step is to add users with the corresponding credentials

  useradd -c "Naweed Sayed" -g Finance -g Accountant SNaweed

  useradd -c "Said Sadat" -g Finance SSaid

useradd -c "John Smith" -g Finance SJohn

useradd -c "Temp Worker" -g Finance -e 2020-12-25 HAli

useradd -c "Jenny Daniel" -g HumanResources DJenny

useradd -c "Michael Prince" -g HumanResources MPrince

useradd -c "Faheem Nazeri" -g HumanResources NFaheem

useradd -c "Ahmad Mushtiq" -g IT -g Developer MAhmad

  useradd -c "Kushbu Patel" -g IT -g Admin PKushbu

+ root@ubuntu: Q o -g -g root@ubuntu:-# useradd -C root@ubuntu:~# useradd -C root@ubuntu:~# useradd -C root@ubuntu:-# useradd -C root@ubuntu:~# useradd -C root@ubuntu:~# useradd -C root@ubuntu:# useradd -C root@ubuntu:~# useradd -C root@ubuntu:~# useradd -C root@ubuntu:~# "Naweed Sayed" Finance Accountant SNaweed "Said Sadat" -g Finance SSaid "John Smith" - 9 Finance SJohn "Temp Worker" -g Finance -e 2020-12-25 HAli "Jenny Daniel" -g HumanResources DJenny "Michael Prince" - g Human Resources MPrince "Faheem Nazeri" HumanResources NFaheem "Ahmad Mushtiq" -9 IT -g Developer MAhmad "Kushbu Patel -g IT -g Admin PKushbu -g o

Note:

It must be noted that the following options

-c Add comment (includes Full Name)

-g Add primary group

for login name "HAli" an expiry date has been specified using the option "-e"

.

Adding passwd using the command “passwd loginname”

a O + root@ubuntu: - root@ubuntu:-# passwd SNaweed New password: Retype new password: passwd: password updated successfully root@ubuntu:-# passwd SSaid New password: Retype new password: passwd: password updated successfully root@ubuntu:~# passwd SJohn New password: Retype new password: passwd: password updated successfully root@ubuntu:-# passwd Hali New password: Retype new password: passwd: password updated successfully root@ubuntu# asswd DJenny

display the tree structure
