From: RichardOnRails on 11 Jul 2010 13:32 I've got a 3-line bat file: rake ready_for_the_day @echo ------ rake COFFEE_CUPS=5 make_coffee (BTW: Rake is Ruby's version of make: it invokes Ruby commands rather the U*ix cmds. The arguments identify a task within a Rakefile in the current directory, possibly with settings for environment variables) The above ,bat file invokes the first command successfully, AFAIK, and then quits When I comment out the first cmd with a leading colon the echo works, as does the 2nd cmd Could a Rake.exe shut down the batch cmd that invoked it. If so, is there any way I could insulate the batch command file from such a shutdown attempt? Thanks in Advance, Richard

I just remembered this question I similar to one I asked the other day. There the answer was "invoked commands like rake as follows: cmd /c the.exe That worked here, too. Best wishes, Richard

Rake.exe has no path in your example.

True, but Rake's path is provided in my installation of Ruby: K:/ _Utilities/ruby186-26_rc2/ruby/bin/ (BTW, Ruby adjusts path separators to the OS environment.) I looked up the specs on cmd and start. It looks like they were drawn up by lawyers :-) In your view, is there a reason to prefer "start /b" to "cmd /c"? Thanks in Advance, Richard

I'm coming in late on this but given the subject of thread ... I wrote a program (EXE) years ago as a menu front end that rewrote the batch file it was invoked from. The edits were what got parsed when the exe finished, the new line(s) executed, returned to batch file, looped to top of it, reinvoked exe which would change it again to new selection etc. etc. In other words the batch file got reparsed after return from the exe.
