This post is simple and helpful for how to compare multiple strings by shell scripting. For example can check the country name which one is available.


#!/bin/bash
echo -n "Enter Your Country Name :"
read  countryname

if [ $countryname != "india" ] && [ "$countryname" != "usa" ] && [ "$countryname" != "japan" ] ; then
  echo "";
  echo "Your Country code does not match..."
  exit 1;
else
  echo "";
  echo "The Country Name is Available :  $countryname"
fi

Output :

Enter Your Country Name : 
india

The Country Name is Available : india
