Have satisfactorily completed the requirements
of the Mini Project Of subject
• “Operating System”
• As prescribed by the University of Mumbai Under the guidance of
• Prof. “Pramila Mate”
1.INTRODUCTION
• P.T.O
Objective of OS Project on SI and CI
calculator:
• The main objective of this project is to calculate the SI & CI in faster
and in most reliable way. This means you can do multiple calculations
in minutes whereas calculations may take more time on paper.
What Is Simple Interest?
• Simple interest is a quick and easy method of calculating the interest
charge on a loan. Simple interest is determined by multiplying the
daily interest rate by the principal by the number of days that elapse
between payments.
• Simple Interest=P×I×N where: P=principle
• I=daily interest rate
• N=number of days between payments
What Is Compound Interest?
• Compound interest (or compounding interest) is interest calculated on
the initial principal, which also includes all of the accumulated interest
of previous periods of a deposit or loan.
• Compound Interest = Total amount of Principal and Interest in future
• (or Future Value) less Principal amount at present (or Present Value)
• = [P (1 + i)n] – P
• = P [(1 + i)n – 1]
• (Where P = Principal, i = nominal annual interest rate in percentage
terms, and n = number of compounding periods.)
2.PROBLEM STATEMENT
• Creating a Simple Interest and Compound Interest Calculator using bash script in Linux.
• Objective of Project –
• The main objective of this project is to create a user friendly and efficient system for calculation of the EMI,
which saves the user’s valuable time and efforts.
• About shell script: • A shell script is a computer program designed to be run by the Unix shell, a command-line interpreter.
• Bash is a command processor that typically runs in a text window where the user types commands that cause
actions. Bash can also read and execute commands from a file, called a shell script.
• System requirements –
• Linux/Unix Operating system
• Or
• Windows Operating System (With Unix environment provided by Cygwin.exe)
• + Notepad / Notepad++ (For Writing Shell Commands)
3.IMPLEMENTATION

•
#!/usr/bin/env bash
while [ 1 ]
do
echo "Menu"
echo "1. Simple Interest"
echo "2. Compound Interest"
echo "3. Exit"
echo "Enter the Choice"
read choice
case $choice in

•
•
1) echo "Enter the value of p,t and r"
read p
read t
read r
si=`echo "scale=2;( $p * $t * $r)/100" | bc`
echo "Simple Interest = $si" ;;

2) echo "enter the value of p, t, r and n"
read p
read t
read r
read n
power=`expr $n \* $t`
echo $power
ci=`echo "scale=2; ($p*(1 + $r/$n ) ) ^ $power" | bc`
• echo "Compound Interest = $ci" ;;
• 3) exit;;
• *) echo "Invalid Choice";;
• esac
• done
4.OUTPUT (Using Cygwin):
5.CONCLUSION
• Finally, we have developed a secure, user-friendly EMI calculator
system for calculation of EMI. With the help of this system, user can
calculate EMI in efficient and in faster way.
