$4$

$5$

$2)$ Set each user with the password: password

$3)$ Create the following five groups:

$$ math

$$ sports

Section One $/$ Part B

Explain each of the steps you have followed to complete the Tasks $15$ given above.

The explanation will include:

$6)$ The commands used, including flags.

$7)$ Screenshots demonstrating the command input and the result.

$8)$ Output of files such as $/$etc$/$passwd and demonstrate that the home directories and groups have been successfully added.

$9)$ Show that $1$ has superuser privileges.

$10)$ Include an output of your command history file that shows the use of each of the commands that you have explained.

$11)$ Create directories for each department $($math$,$ sports, HR$,$ IT$,$ marketing$)$ at the root of the filesystem.

$12)$ Configure standard Linux permissions and ownership such that each group only has access to its own departmental directories.

$13)$ Use Octal permissions to permit one user $($and only one user$)$ account to have read permission to the $/$IT directory.

$14)$ Add another one of your existing user accounts to the sports group.

$15)$ Use each of these two user$$s accounts to create one file each in the $/$sports directory.

$16)$ Create a file named LinksTest.txt in the $/$opt directory, and then create a symbolic link to it in the $/$math directory called link.

$17)$ Use Vim to add the following line of text to the file LinksTest.txt through the $/$opt$/$LinksTest$.$txt path $$This is the line that I have added$.$

$18)$ Create $5$ files in the $/$tmp directory: $1.$txt$,2.$txt$,3.$txt$,4.$txt$,5.$txt$.$

$19)$ Use tar and gzip to bundle and compress the files.

$20)$ Extract these files to $1$s home directory from your tarball.anage Files and Backups.

Explain each of the steps you have followed to complete the Tasks $615$ given above.

The explanation will include:

$21)$ The commands used, including flags.

$22)$ Screenshots demonstrating the command input and the result.

$23)$ One screenshot demonstration that the permissions have been set, $($For example, the sports group has access to the $/$sports directory but not to other departments' directories.$)$

$24)$ Output of files $($such as $/$etc$/$passwd$)$ to demonstrate that the home directories and groups have been successfully added.

$25)$ An output of your command history file that shows the use of each of the commands that you have explained.

Use Vim to create $/$ edit these scripts. $($Please$,$ do not use a GUI editor or nano.$)$

$26)$ Create a bash script file called $$sys$.$sh$$ using the following information: $($Cut and paste the

following into your Vim editor$)$

#$!/$bin$/$bash

echo "System Information:"

echo $"-------------------"$

echo "Hostname: $$($hostname$)"$

echo "Operating System: $$($lsb$\_$release $-$d $|$ cut $-$f $2)"$

echo "Kernel Version: $$($uname $-$r$)"$

echo "CPU Information: $$($lscpu $|$ grep "Model name:" $|$ cut $-$d$\text{'}$:$\text{'}-$f $2|$ sed $-$e $\text{'}$s$/^[[$:space:$]]*//\text{'})"$

echo "Memory: $$($free $-$h $|$ awk $\text{'}/^$Mem:$/\{$print $$2\}\text{'})"$

echo "Disk Space: $$($df $-$h $|$ awk $\text{'}$$NF$=="/"\{$printf $"\%$s$/\%$s $(\%$s$)$

$",$ $$3,$$$2,$$$5\}\text{'})"$

Insert a Screenshot of the Vim editor before saving the file here:

$27)$ Run the sys$.$sh script $($If the script does not run, there will be a simple and logical reason

behind this. Please don$$t email me to ask why.$)$

Insert a screenshot that shows the output of the script here:

$28)$ Very briefly $(12$ Sentences, $15$ word sentences max$)$ Explain what task the script is

performing, $($This can be described in $1$ sentence$)$ Here:

$29)$ Create a bash script file called $$user$.$sh$$ using the following information:

$($Cut and paste the following into your Vim editor$)$

#$!/$bin$/$bash

read $-$p "Enter username: $"$ username

if id $"$$username" $>/$dev$/$null $2>$&$1$; then

echo "User $\text{'}$$username' already exists."

else

# Create the user

sudo useradd $-$m $"$$username"

echo "User $\text{'}$$username' created successfully."

fi

Insert a Screenshot of the Vim editor before saving the file here:

$30)$ Run the user.sh script twice

use $1$ that you created above as the first script run

and testuser$1$ as the second script run.

Insert a screenshot that shows the output of both script runs here: $(2$ screenshots please$)$

$31)$ Explain each step of the user.sh bash script here:

$(1$ sentence, of no more than $15$ words, for each step$)$

$32)$ Using Vim, create a simple bash script that displays as an output:

$$ The current user name.

$$ The current user$$s shell.

$$ The groups that the current user is a member of

$$ The current date & time

Use remarks within the script to document each step.

The output must display a description of the result $($such as: $$The current Date & Time is: $)$
