I have written following code
setlocal set /A sample =1 :first type C:\test.txt | find "inserted" if %ERRORLEVEL% EQU 0 goto test if %ERRORLEVEL% EQU 1 goto exam :test echo "testloop" >> C:\testloop.txt set /A sample = %sample% + 1 if %sample% LEQ 4 goto first :exam echo "exam loop" >> C:\examloop.txt endlocal but it is going to lable "exam" even though error level is not equal to "1" plz help me

Your problem isn't goto, its that errorlevel requires special treatment, it's not like an ordinary environment variable. The only test you can do with errorlevel is to test whether it is greater than or equal to value.
so you have to test errorlevel values from highest to lowest because if errorlevel 1 then if errorlevel 1 will be true, but if errorlevel 0 will also be true
setlocal set /A sample =1 :first type C:\test.txt | find "inserted" if errorlevel 1 goto exam if errorlevel 0 goto test :test echo "testloop" >> C:\testloop.txt set /A sample = %sample% + 1 if %sample% LEQ 4 goto first :exam echo "exam loop" >> C:\examloop.txt endlocal if you have command extensions enabled, and there is no environment variable called ERRORLEVEL (case insensitive). Then in theory you can use %ERRORLEVEL% like an ordinary environment variable. So this should also work
setlocal EnableExtensions set /A sample =1 :first type C:\test.txt | find "inserted" if %errorlevel% EQU 1 goto exam if %errorlevel% EQU 0 goto test :test echo "testloop" >> C:\testloop.txt set /A sample = %sample% + 1 if %sample% LEQ 4 goto first :exam echo "exam loop" >> C:\examloop.txt You need to list the error levels in descending order (errorlevel2, errorlevel1, errorlevel0...).
See this explanation and example.
You may want to consider using ERRORLEVEL as direct branching as follows:
setlocal set /A sample =1 :first type C:\test.txt | find "inserted" **goto :Branch%ERRORLEVEL%** :Branch0 echo "testloop" >> C:\testloop.txt set /A sample = %sample% + 1 if %sample% LEQ 4 goto first :Branch1 echo "exam loop" >> C:\examloop.txt endlocal May be use || instead of errorlevel for branching.
setlocal set /a sample=1 :first (Type c:\test.txt | find "inserted" >> c:\testloop.txt) || goto :branch1 set /a sample+=1 If %sample% leq 4 goto :first :brabch1 Echo "exam loop" >> c:\examloop.txt More simple way to use for loop.
For /l %%a in (1,1,4) do (
(Type c:\test.txt | find “inserted” >> c:\testloop.txt) || goto :done
)
:done
Echo “exam loop” >> c:\examloop.txt
Goto :eof
0
