Question

****USING BASH****

Write a function that takes an input temperature (Celsius or Fahrenheit) from the user converts that temperature Celsius to Fahrenheit, Fahrenheit to Celsius, Celsius to Kelvin and Fahrenheit to Kelvin.

Answer 1

Here is a script that takes Celsius from the user and then converts Celsius to Fahrenheit, Fahrenheit to Celsius, Celsius to Kelvin and Fahrenheit to Kelvin

Formula:

Celsius to Fahrenheit - (0°C × 9/5) + 32 = 32°F

Fahrenheit to Celsius - (32°F − 32) × 5/9 = 0°C

Celsius to Kelvin - 0°C + 273.15 = 273.15K

Fahrenheit to Kelvin - (32°F − 32) × 5/9 + 273.15 = 273.15K

echo

echo command in linux is used to display line of text/string that are passed as an argument

read

read command in Linux system is used to read from a file descriptor

#!/bin/bash

functionn () {

echo -n "Enter temperature (C) : "

read tc

tf=$(echo "scale=2;((9/5) * $tc) + 32" |bc)

tk=$(echo "scale=2;$tc + 273.15" |bc)

echo "$tc Celsius = $tf Fahrenheit"

echo "$tc Celsius = $tk Kelvin"

tc=$(echo "scale=2;(5/9)*($tf-32)"|bc)

tkk=$(echo "scale=2;(5/9)*($tf-32) + 273.15"|bc)

echo "$tf Fahrenheit = $tc Celsius"

echo "$tf Fahrenheit = $tkk Kelvin"

  

  

}

function
