How to check if a service is running via batch file and start it, if it is not running?

Question

I want to write a batch file that performs the following operations:

• Check if a service is running
  • If is it running, quit the batch
  • If it is not running, start the service

The code samples I googled so far turned out not to be working, so I decided not to post them.

Starting a service is done by:

net start "SERVICENAME" 

1. How can I check if a service is running, and how to make an if statement in a batchfile?
2. I'm a bit confused. What is the argument I have to pass onto the net start? The service name or its display name?

Answer 1

To check a service's state, use sc query <SERVICE_NAME>. For if blocks in batch files, check the documentation.

The following code will check the status of the service MyServiceName and start it if it is not running (the if block will be executed if the service is not running):

for /F "tokens=3 delims=: " %%H in ('sc query "MyServiceName" ^| findstr "        STATE"') do (   if /I "%%H" NEQ "RUNNING" (    REM Put your code you want to execute here    REM For example, the following line    net start "MyServiceName"   ) ) 

Explanation of what it does:

1. Queries the properties of the service.
2. Looks for the line containing the text "STATE"
3. Tokenizes that line, and pulls out the 3rd token, which is the one containing the state of the service.
4. Tests the resulting state against the string "RUNNING"

As for your second question, the argument you will want to pass to net start is the service name, not the display name.
