Checking numbers

Also, in the same way, we can check numbers using the test and the if commands.

#!/bin/bash 
if [ 12 -gt 10 ] 
then 
echo "number1 is greater than number2" 
else 
echo "number1 is less than number2" 
fi  

As expected, 12 is greater than 10.

All other numeric tests work the same way.
