I know that using sc start/stop service name to start and stop services, but now I want to first judge whether the service is on or off. If it's on, close the service; if the service is off, start the service. How to achieve this? Is it using the query parameter? I'm just learning batch processing, please experts give me some pointers.

The error is in the judgment condition. The correct way should be to check if the result is equal to 4. The current `if not errorlevel 4` is wrong. The correct code should be:

@echo off
sc query vmauthdservice >query.txt
for /f "tokens=3 delims=: " %%a in ('find "STATE" query.txt') do set "state=%%a"
if %state% equ 4 (sc stop vmauthdservice) else (sc start vmauthdservice)

I just don't know how to use this value to make a judgment

How to do it right? I also want to know.

May I ask lxmxn, what do those "half" parentheses mean? And there's a parenthesis that takes up a whole line, what does that mean? Can you explain? Do parentheses have special usages?

Thank you very much. This service is for virtual machine. I usually set it to manual and start the service when using the virtual machine, so I won't set the service startup type. Just treat it as learning knowledge, hehe.

But there are still some places I don't understand, such as "delims=", "%%i", "^. I have only read some simple batch processing tutorials before, which only introduce common commands. Where is there a more comprehensive explanation tutorial? I want to learn.

The function of that bat of lxmxn:
If the service has started, let it stop;
If the service has stopped, let it start;
Is it like this?

There is no SC command under 2000?

@echo off
for /f "delims=" %%i in ('SC QUERY TLNTSVR^|FIND "STATE"') do ( Understood this, do the work after DO according to STATE)
echo %%i|find /i "RUNNING" && ( If it is "running" state, what is &&?
sc stop tlntsvr SC command to stop TELNET service
sc config tlntsvr start= disabled)||( SC permanently configure TELNET to not enable But what does || mean?
sc config tlntsvr start= auto SC start TELNET to automatic, start TELNET
sc start tlntsvr)
)
exit/b

But...

The owner is the same as me, heh heh
I like to start those nat, dhcp services only when using vmware, so I wrote a script to detect and switch services

If you are also using vmware, it's very simple because these services will generate processes after starting
Like vmnat.exe, just confirm with tasklist|find

net start|find can also work :D
