Can you provide simple instructions that demonstrate the issue without requiring a database? By "cmd shell", do you mean Cygwin bash running in a console window, or do you mean the actual Windows command processor (the one that prompts with 'C:\Users\name>'). > The mintty terminal handles this fine as per Typical true bash environments > on UNIX servers > - the cmd shell seems to require another configuration to enable variables > to be inherited in a script from the outer shell - this I don't presently > know how That sounds a bit confused. Let me try to clarify things a bit. Cmd.exe and the console window are not the same thing. Cmd.exe is a command processor, similar in concept (if not implementation) to Unix shells such as bash. They all just take text input and produce text output and they don't concern themselves with displaying a window or anything like that. When you invoke a console application such as cmd.exe or bash.exe from Explorer, Windows automatically creates a console window for it that turns key presses into text input and that display text output on the screen. On Windows 7, that's implemented by conhost.exe. Meanwhile, mintty is similar to conhost.exe in that it sends keyboard input to the program running inside it and displays output coming back from the program. You can set the program to run in it on the mintty command line. By default, that's bash, i.e. no matter whether you invoke the "Cygwin Bash Shell" or the "mintty" shortcut, it's normally bash that's processing your commands. To summarise: Console/terminal: conhost, mintty, rxvt, xterm ... Command processor/shell: cmd, bash, tcsh, zsh, ... There are important differences between Windows consoles and Unix terminals as well, but let's leave those for now ...
