How can the Windows Command Line do a grep -o?

Question

Is there a way in Windows to get a matching string within a string?

echo hereisastring | find "is"  and just display is

without using grep

The following worked using FIND. credit to Hello71

C:\>echo abcd | find "bc" >nul && if errorlevel 0 echo bc
bc

	C:\test>echo abcd \| find "bc" if errorlevel 0 echo "bc" <-- doesn't seem to work. Does this have to be multiple lines? does it have to use environment variables? – barlop May 8 '11 at 20:13
	Can you give a full working example? I don't really understand why at one point you've put an environment variable in quotations and in another point not. – barlop May 8 '11 at 20:32
	@barlop: You need to use && to separate commands in Command Prompt. `FIND` requires its parameter to be in quotes. – Hello71 May 8 '11 at 21:01
	@Hello71 I couldn't get the example with environment variables to work because set is a bit funny, putting spaces or new lines in. Have you managed to get it to work with environment variables? I did get it working without though. – barlop May 8 '11 at 21:59
	@barlop: The environment variables were for the purpose of the example. – Hello71 May 8 '11 at 22:06
