Example 1: greater than in script
-eq is equal to if [ "$a" -eq "$b" ] -ne is not equal to if [ "$a" -ne "$b" ] -gt is greater than if [ "$a" -gt "$b" ] -ge is greater than or equal to if [ "$a" -ge "$b" ] -lt is less than if [ "$a" -lt "$b" ] -le is less than or equal to if [ "$a" -le "$b" ]
Example 2: test string equality bash
strval1="Ubuntu" strval2="Windows" #Check equality two string variables if [ $strval1 == $strval2 ]; then echo "Strings are equal" else echo "Strings are not equal" fi #Check equality of a variable with a string value if [ $strval1 == "Ubuntu" ]; then echo "Linux operating system" else echo "Windows operating system" fi
