Shell Script to Convert Distance Units

Linux shell script allows you to calculate the user input number to display in different units. This will be achieved by using the bc command. bc command is used for the command-line calculator.

vi convert_distance.sh

# !/bin/bash 

echo "Enter distance (in km) : "
read km

meter=`echo $km \* 1000 | bc`
feet=`echo $meter \* 3.2808 | bc`
inches=`echo $feet \* 12 | bc`
cm=`echo $feet \* 30.48 | bc`

echo "Total meter is    : $meter "
echo "Total feet is     : $feet "
echo "Total inches is   : $inches "
echo "Total centimeters : $cm "

Here is the sample output of the above script
