Write a shell script about a temperature convert Fahrenheit to celsium?

Answer 1

echo "*** Converting between the different temperature scales ***"

echo "1. Convert Celsius temperature into Fahrenheit"

echo "2. Convert Fahrenheit temperatures into Celsius"

echo -n "Select your choice (1-2) : "

read choice

if [ $choice -eq 1 ]

then

echo -n "Enter temperature (C) : "

read tc

# formula Tf=(9/5)*Tc+32

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

echo "$tc C = $tf F"

elif [ $choice -eq 2 ]

then

echo -n "Enter temperature (F) : "

read tf

# formula Tc=(5/9)*(Tf-32)

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

echo "$tf = $tc"

else

echo "Please select 1 or 2 only"

exit 1

fi

Answer 2

Sure! Here is a simple shell script to convert temperature from Fahrenheit to Celsius:

#!/bin/bash
echo -n "Enter temperature in Fahrenheit: "
read fahrenheit
celsius=$(echo "scale=2; ($fahrenheit - 32) * 5/9" | bc)
echo "Temperature in Celsius is: $celsius °C"

You can save this script in a file, make it executable, and then run it in the terminal to convert Fahrenheit to Celsius.
