Планировщик заданий ошибка 0xff

I have a scheduled task that runs a batch file, and even though I can see the results of it completing successfully, according to the task scheduler it fails with error 0xff, every time.

I have other batch files scheduled that also complete successfully and return 0x0 as they should. The only difference I can see between these files is that the working ones end with:

IF ERRORLEVEL 1 (
    ("notify me" script here)
)

whereas the broken one ends with:

IF %2==something (
    (run a program here)
    IF ERRORLEVEL 1 (
        (same "notify me" script here)
    )
)

Does an IF block return 0xff if false or something? What’s the deal?

IF "%2"=="SOMETHING" (

IF ==SOMETHING (

IF ""=="SOMETHING" (

1

After some testing, I figured out that IF blocks are okay, they don’t seem to change the error level, but what was messing it up was the «%2==something»—the times that were failing, there was no second parameter being passed to the batch file. So I’m not sure how to «safely» test for whether a parameter exists (i.e., without it erroring out 0xff when it’s not there) except maybe to have yet another IF ERRORLEVEL after that. But anyway, I just changed the scheduled task so it will always have a second parameter (whether it’s «something» or not) and it seems to return 0x0 as it should now.

• You must capture the error generated by your batch file command, e.g. like so:

  @echo off
  if not exist c:\Logs md c:\Logs
  echo %date% %time% 1>>c:\Logs\Task.log 
  net start «MyService»  1>>c:\Logs\Task.log 2>>&1 

  The contents of the log file should tell you what’s wrong.
