Your 'default' shell was likely sh, not bash. It is SOP to put
#!/path/to/command/interpreter
in the first line of shell command files. This also applies to
command files for Perl, etc.,
In Unixae, exec() reads the first line and starts the indicated
interpreter; I think Cygwin1.dll handles this, here. If the line
isn't there, the 'current' interpreter is used (e.g. $SHELL).
