How to handle multiple IF conditions in a batch scripting
Ex:-
IF %Ti% EQU 2 ( first if start
do this
do this
do this
do this
IF "%clc%" GEQ "800" set /a yy=%yy%+1
IF "%Day%" GTR "1" set /a yy=%yy%+1
IF %yy% LEQ 2 (
taskkill /F /IM calc.exe
) ELSE (
taskkill /F /IM notepad.exe
)
) ELSE ( first if end
echo Bye Bye
)

Thanks in advanceWe do not know what your "do this" code does so cannot give detailed help. However, in a multi line IF structure, you need to use delayed expansion to set and read variables to work properly. You can Google for many pages about this.

Dear Salmon Trout,
Pls find the code,
How to handle multiple IF conditions in a batch scripting
Ex:-

For /f "tokens=5" %%i in (6.txt) do set ci=%%i
IF %ci% EQU 2 ( [B] first if start[/b]
For /f "tokens=3" %%i in (6.txt) do set Tl=%%i
set Th=%Tl:~0,2%
set Tm=%Tl:~3,2%
Set TL=%Th%%Tm%
For /f "tokens=2" %%J in (4.txt) do set Tj=%%j
set /A Clc=%Tf%-%TL%
set /A Day=%dt%-%Tj%
:del 4.txt
echo %clc%
echo %Day%
set bool=0
[i]IF "%clc%" GEQ "800" set /a yy=%yy%+1
IF "%Day%" GTR "1" set /a yy=%yy%+1
IF %yy% LEQ 2 (
taskkill /F /IM calc.exe
) ELSE (
taskkill /F /IM notepad.exe
)
)[/i] ELSE ( [b]first if end[/b]
echo Bye Bye
)

Pls ADVICE,
Thanks in ADVANCE 1. Normally, cmd.exe expands variables ONCE only, at parse time.
So with variables set and expanded inside parentheses e.g:

FOR bla bla BA (
set var=abc
echo %var%
)

or

IF bla bla bla (
set var=abc
echo %var%
)

... the variable %var% is unknown at parse time, so is blank.
If it was set before the parentheses start, it retains that value.

Solution:
-- use delayed expansion, enable it at the start of the batch
-- use ! exclamation points instead of % percent signs for those
variables which are both set and expanded inside the parentheses.
(can use % signs to expand those variables after the parentheses end.)

REM Put this line near the start of the batch. Only need it once.
setlocal enabledelayedexpansion
FOR bla bla ba (
set var=abc
echo !var!
)

IF bla bla bla (
set var=abc
echo !var!
)

2. Each IF can have only 1 ELSE. Therefore redesign logic.

e.g. use labels and goto

if "%animal%"=="CAT" goto meow
if "%animal%"=="DOG" goto grrrr
goto other

:meow
echo animal is a cat
goto next

:grrrr
echo animal is a dog
goto next

:other
echo animal is something else
goto next

:next
echo next part of code
