Problem with output from this FOR command

Question

I just realized I'm executing a bat file at the start at this registry key, that had echo running abc and some other irrelevant things

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun

So here I've modified that bat file.. it is just one line nothing irrelevant in it.

you see the contents of the bat file.

Here is some output from the cmd prompt showing the situation now which is the same fundamental problem but you should be able to reproduce the problem

The question now is,

• Why does it say echo sss and not echo sss ttt?
• How can I suppress the running of cmd or that initialization bat file with the FOR? The FOR statement should really just display "echo g", not "echo sss" or "echo sss ttt".

If you're going to use %f in a batch file, you need to escape it with another %:

for /f %%f in ('echo g ^| findstr "g"') do echo %%f

Put that in your batch file and you should get the results you're looking for.
