Re: Inconsistence on file operation when the name already exists with exe extension

You're comparing apples to oranges.
You've been told already that Cygwin doesn't try to emulate windows shells or
anything of that kind.

No, he's talking about CreateProcess[Ex]() function call.
It's possible to execute binary with arbitrary name, since at least Win NT 4.x
if memory serves me well.

You're confusing shell with terminal... don't you?
mintty.exe -h -e C:\WINDOWS\system32\cmd.exe /K

You'll be surprised.

I do like to mix things. Alot. Life is just not the same without that.
