批處理腳本語言支持關係運算符。以下代碼片段顯示了如何使用關係運算符。
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
執行上面示例代碼，得到以下結果 -
A is not equal to than B
A is less than B
A is less than or equal B
