120} How do I use AND/OR/XOR/NOT operators in an IF statement?
@echo off & setlocal enableextensions
if [%2]==[] (
echo Usage %~dpn0 var1 var2
goto :EOF)
set var1=%~1
set var2=%~2
::
if "%var1%"=="Timo" if "%var2%"=="Salmi" echo Timo AND Salmi
::
set or_=
if "%var1%"=="Timo" set or_=true
if "%var2%"=="Salmi" set or_=true
if defined or_ echo Timo OR Salmi
::
set xor_=
if "%var1%"=="Timo" set xor_=true
if "%var2%"=="Salmi" set xor_=true
if "%var1%"=="Timo" if "%var2%"=="Salmi" set xor_=
if defined xor_ echo Timo XOR Salmi
::
if not "%var1%"=="Timo" echo Not Timo
if not "%var2%"=="Salmi" echo Not Salmi
::
endlocal & goto :EOF
The output could be e.g.
C:\_D\TEST>cmdfaq Timo Salmi
Timo AND Salmi
Timo OR Salmi
C:\_D\TEST>cmdfaq Timo testing
Timo OR Salmi
Timo XOR Salmi
Not Salmi
C:\_D\TEST>cmdfaq Still testing
Not Timo
Not Salmi
Alternatively, the OR test could be written as
set or_=true
if not "%var1%"=="Timo" if not "%var2%"=="Salmi" set or_=
if defined or_ (echo Timo OR Salmi) else (echo Neither)
Yet another way of testing an OR condition
@echo off & setlocal enableextensions
if "%~1"=="" (
echo Usage %~dpn0 var1
goto :EOF)
::
echo %~1|findstr /c:"Timo" /c:"Salmi">nul
&&echo Timo OR Salmi
||echo Neither
endlocal & goto :EOF
The output might be
C:\_D\TEST>cmdfaq Timo
Timo OR Salmi
or
C:\_D\TEST>cmdfaq Foo
Neither
Consider a variation of the task. If you have two variables (var1 and
var2) test whether either (or both) have the value "Timo".
@echo off & setlocal enableextensions
if [%2]==[] (
echo Usage %~dpn0 var1 var2
goto :EOF)
set var1=%~1
set var2=%~2
::
set or_=
for %%a in ("%var1%" "%var2%") do if %%a=="Timo" set or_=true
if defined or_ (echo Timo was found) else (echo Timo was not found)
endlocal & goto :EOF
The output might be
C:\_D\TEST>cmdfaq Timo Salmi
Timo was found
