I'm looking for a way to check the returncode / errorlevel of the SC command in a DOS script. How can I get this information ?

In most cases you can just check the value of %errorlevel%.

echo %errorlevel%

However, your comment seems to be correct that the %errorlevel% is useless for sc in particular. I'll keep the links included below for people who still want to read about %errorlevel% and application exit codes, but it appears I have not answered your question.

if you try the errorlevel with the SC command you will find out that it doesn't work. Why the SC command is so special in this case I don't know. working with net start / net stop the %errorlevel% is reliable. (I'm aware of the speciality if this old fellow and use it accordingly). –  nojetlag Mar 23 '11 at 16:08
    
You can always obtain the errorlevel; it's virtually impossible for a program not to have one. But it is very well possible that the errorlevel is always 0. Having non-zero errorlevels is special. –  MSalters Nov 27 at 15:13

I suspect you are mostly after the information whether the command succeeded or not. In that case you can simply use

if not errorlevel 1 ...

which will execute the ... part if the last exit code was 0. (It gets a little more complicated than that, but you can ignore that for the most part).

Checking the pseudo-variable %errorlevel% can be dangerous because if someone set a variable with that name before, its value will overshadow the pseudo-variable expansion.

thanks, aware of this, however as mentioned above, SC command is not playing nicely with errorlevel. –  nojetlag Mar 23 '11 at 16:08
