Re: [Realtimebattle-discussion] Signal and Python

[Discussions c. R. <rea...@li...>]

Hi Joannes,

I am testing under linux.

As I could not (do not know how to) pass stdin from a .sh to my .py, I do n=
ot=20
have any shell wrapper but have rtb point directly to my "snake.robot" whic=
h=20
is a python executable.

Regards,

Philippe
