If I launch a Windows command shell (cmd.exe) from, e.g. a Window shortcut,
and then run bash from that shell, bash starts interactive mode.
If I launch a Cygwin bash shell from, e.g. cygwin.bat, then run cmd from
that shell (I type cmd), a Windows command shell starts. If I then run bash
from that command shell, bash starts in non-interactive mode.

Can anyone explain this behaviour and why bash starts in interactive mode in
one case, and non-interactive mode in the other, even though both times it
is launched from cmd.exe?

Chris

Starting bash from cmd.exe started from bash:

^^^ bash is running in interactive mode.
