批處理指令碼 - 關係運算符

關係運算符允許比較物件。以下是可用的關係運算符。

以下程式碼片段演示瞭如何使用各種運算子。

示例

@echo off 
SET /A a = 5 
SET /A b = 10 
if %a% EQU %b% echo A is equal to than B 
if %a% NEQ %b% echo A is not equal to than B 
if %a% LSS %b% echo A is less than B 
if %a% LEQ %b% echo A is less than or equal B
if %a% GTR %b% echo A is greater than B 
if %a% GEQ %b% echo A is greater than or equal to B

輸出

以上命令產生以下輸出。

A is not equal to than B
A is less than B
A is less than or equal B
