ge	INTEGER1 -ge INTEGER2	INTEGER1 is greater than or equal to INTEGER2	#!/bin/bash read -p "Enter number >= 10 : " n if test $n -ge 10 then     echo "$n is greater than or equal to 10" fi
gt	INTEGER1 -gt INTEGER2	INTEGER1 is greater than INTEGER2	#!/bin/bash read -p "Enter number > 20 : " n if test $n -gt 20 then     echo "$n is greater than 20." fi
le	INTEGER1 -le INTEGER2	INTEGER1 is less than or equal to INTEGER2	#!/bin/bash read -p "Enter backup level : " n if test $n -le 6 then     echo "Incremental backup requested." fi if test $n -eq 7 then     echo "Full backup requested." fi
lt	INTEGER1 -lt INTEGER2	INTEGER1 is less than INTEGER2	#!/bin/bash read -p "Do not enter negative number here : " n if test $n -lt 0 then     echo "Dam! you entered negative number!!" fi
ne	INTEGER1 -ne INTEGER2	INTEGER1 is not equal to INTEGER2	#!/bin/bash read -p "Do not enter -1 number here : " n if test $n -ne -1 then     echo "Thanks for not entering -1." fi
