TODO in shell scripting

 

Write a shell script (todo.sh ) to do a simple calculator for mathematics operation [ - , + , * , % , / ]

And to convert from decimal to octal or hexadecimal ( the operation is > for this case).

 

You have to read three inputs ( number1, operation, number2)then test the following:

1-      The first and the third inputs are numbers (might be more than one digit),

2-      The second input is a mathematics operation [ - , + , * , % , / ] or [ >] to convert from decimal to other base

3-      If all previous conditions are true, the output should be the result for the inputs you passed.

4-      If the operation is > , then number1 is the number you want to convert, and number2 is the output base.

5-      If there is a problem in any condition, you should display an error message that show the user what was the error in his inputs.

6-      Ask user if he want to try other inputs ( user must enter “N” to end program)

  

Examples:

Please enter  number1: 12

Pleas enter operation: +

Please enter number2: 220

The result is 232

Do you want to continue: Y

 

Please enter  number1: 12

Pleas enter operation: !

Please enter number2: 220

Please enter a valid operation!

Do you want to continue: Y

 

 

 

Please enter  number1: 10

Pleas enter operation: >

Please enter number2: 8

The result is 12

Do you want to continue: Y

 

Please enter  number1: b

Pleas enter operation: %

Please enter number2: 56

Number1 is invalid!

Do you want to continue: Y

 

Please enter  number1: 125

Pleas enter operation: >

Please enter number2: 16

The result is 7D

Do you want to continue: N
