In fact, that's exactly what you'd expect, come to think of it. When
cmd.exe processes a command in a batch file, it doesn't redirect the
contents of the batch file into the stdin for that command. It executes
the command program and waits for it to complete before reading more of
the batch file. You wouldn't expect this to work, would you:
-----wont_work.bat-----
notepad.exe
Hello, this will NOT end up as text in the notepad document
-----wont_work.bat-----
cmd.exe doesn't understand that bash.exe is a command shell, it just
treats it like any other program that's called from a batch file, and in
particular it doesn't pipe any input to it, from the batch file or
anywhere else.
To get the effect you want, you should really put the bash commands
into a separate file and then use "bash -s < filename" (or even "cat
filename | bash -s" I suppose). If you want to keep things localized in
the one file, you could use echo instructions to build a temporary
script file. It's a shame that cmd.exe doesn't support here docs.
cheers,
