Write a script to display the time every 15 seconds. Read the date man page and display the time, using the %r field descriptor. Clear the window (using the clear command) each time before you display the time.

Explanation:

An infinite bash while loop can be used to implement the logic

The syntax of infinite bash while loop is

while :

do

# statements

done

We can create any desired date and time format by utilizing the field descriptors. Field descriptors denote various components of date and time

For example:

date +  %r       %I:%M:%S %p

date + %D%m/%d/%y

date + %R%H:%M

echo command displays the contents of the variable Time

sleep 15 represents a gap of 15 seconds between the display

Then clear command is used to clear the window

Linux Code:

while :

do

Time ='date + %r'  

echo -n $Time

sleep 15

clear

done
