Batch Script Relational Operators

Learn how to use EQU, NEQ, LSS, LEQ, GTR, and GEQ relational operators in Windows batch scripts to compare values with practical examples and syntax.

Relational operators allow of the comparison of objects.

The following table lists the available relational operators.

Operator	Description	Example
`EQU`	Tests the equality between two objects	`2 EQU 2` will give true
`NEQ`	Tests the difference between two objects	`3 NEQ 2` will give true
`LSS`	Checks to see if the left object is less than the right operand	`2 LSS 3` will give true
`LEQ`	Checks to see if the left object is less than or equal to the right operand	`2 LEQ 3` will give true
`GTR`	Checks to see if the left object is greater than the right operand	`3 GTR 2` will give true
`GEQ`	Checks to see if the left object is greater than or equal to the right operand	`3 GEQ 2` will give true

Example

The following code snippet shows how the various operators can be used.

Example of Relational Operatorsbatch

@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

Outputplaintext

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