In addition to what others said, use "bash -c" instead of "bash" to honor
the shebang ("#!") line.  This would then work for tcsh, ksh, perl,
python, [you name it] scripts, as well as symlinks.  In fact, whenever you
need to invoke a Cygwin program from the DOS prompt, and you don't know if
it's a script, a symlink, or an actual .exe, you can't go wrong with "bash
-c progname".

Adding --login (-l) is optional, but may be useful for scripts that make
assumptions about your environment.
HTH,
	Igor
