Write a Shell script to find sum of two given numbers

CODE

n1=10

n2=20

sum=`expr $n1 + $n2`

echo " SUM = " $sum

Write a shell script to display system date in following format:

Output :

Today is September 24 2009

Today is Thursday

Time is in hh: mm: ss AM/PM

Code :

NOW=$(date +"%B %C %Y")

echo "Today is" $NOW

NNOW=$(date +"%A")

echo "Today is" $NNOW

TTIME=$(date +"%r")

echo "Time is " $TTIME

Output :

$ sy1.sh

Today is March 01 2021

Today is Monday

Time is 10:44:12 AM

An archery target consists of a central circle of yellow surrounded by concentric rings of red, blue, black and white

CODE :

An archery target consists of a central circle of yellow surrounded by concentric rings of red, blue, black and white. Each ring has the same width, which is the same as the radius of the yellow circle. Write a program called target.py that draws this target.

o Use a list of colors and a for loop to draw the target

o Hint: objects drawn later will appear on top of objects drawn earlier

o The output of the program should look like this:
