How to detect (from the command line) if a service is available?

I want to check if a service (in this case: openssh) is available on the local computer.
Normally I could start the service by typing

net start openssh

but this would start the service (if existing). Is there a way to find out
if the service is available without starting it?

What about

sc quesy <service_name>

This probably requires windows xp or 2003.

The following should be all on a single line:

net start | find "openssh" && echo.openssh is running || echo.openssh
not running.
 
This assumes that SC.exe is available:

----------------8<----------------
::ChkSrvc.bat
:: Syntax:
:: ChkSrvc servicename
@echo off
if "%1"=="" goto end
sc query %1 | findstr "SERVICE_NAME">nul
if errorlevel 1 goto notavailable
echo Service %1 available
goto end
:notavailable
echo Service %1 Not available
:end
----------------8<----------------

This is from http://www.pcstats.com/articleview.cfm?articleid=1494&page=4
Right click on 'My computer' and select 'manage.' From the computer
management window, expand 'services and applications' then click 'services'
to open up the window listing all available services. The ones labeled
'started' are currently running, and the startup type 'automatic' denotes a
service which is started by windows each time the operating system loads.

NET START alone will list running services.
To see all installed services you need a different tool.
SC and SCLIST (Resource Kit) or PSSERVICE (Sysinternals)
come to mind. There may be various scripting language or WMI methods
as well.

Have you inspected the output of "NET START"?

One way is:
net start|find /I "openssh">NUL && echo running ||echo not running

Another one (requiring psservice from www.sysinternals.com ) I posted
here:
http://groups.google.com/[email protected]

psservice from sysinternals.com

C:\temp>psservice query openssh

PsService v2.11 - local and remote services viewer/controller

This is all that will be returned if the serivce is not available.

www.sysinternals.com psservice.exe

To find if service installed:
psservice.exe | findstr /i "openssh"

To find if service started:
net start | findstr /i "openssh"

If you type "net start" without parameters it will show you all the running
services. So something like this should work:

@Echo Off
SetLocal
Set SERVICENAME=openssh
Rem You will need to use the service description/long name, not the short
name.
Net.exe Start|Find /i "%SERVICENAME%">NUL
If %errorlevel% EQU 0 (
Echo %SERVICENAME% is running.
) Else (
Echo %SERVICENAME% is not running
)
 
Start/Run/type "services.msc" [less the quote markers]/click "OK". This
will open the list of all system services and you can scroll down to what
you seek.
