[SOLVED] If condition in batch files

If condition in batch files

@echo off
SET var1="Yes"
SET var2="No"
SET var3="Yes"
if %var1%=="Yes"
    echo Var1 set
if %var2%=="Yes"
    echo Var2 set
if %var3%=="Yes"
    echo Var3 set

If I run the above script I get the following error. Can anyone pls help?

The syntax of the command is incorrect.

Thanks.

Solution

The echo needs to either be at the end of the if statement:

if %var1%=="Yes" echo Var1 set

or of the following form:

if %var1%=="Yes" (
    echo Var1 set
)

I tend to use the former for very simple conditionals and the latter for multi-command ones and primitive while statements:

:while1
    if %var1%=="Yes" (
        :: Do something that potentially changes var1
        goto :while1
    )

What your particular piece of code is doing is trying to execute the command if %var1%=="Yes" which is not valid in and of itself.
