Hello,

I would like to display the exit code of a command if it is not 0 on a line
of its own, followed by the prompt on the next line.

Is this possible?

I was able to come up with the following:

PROMPT="%0(?..%?)
%{$fg[green]%}%n@%m%{$reset_color%}:%~ %{$fg[red]%}%#%{$reset_color%} "

However, this prints a newline after every command. Is there some equivalent
of '\n' that can be used inside the conditional substring? Or some other way
to do this?


Yes, a newline works fine.
% PS1='%0(?..%?

Thanks Mikael, there's an obvious solution I've overlooked while it wasstaring me in the face. ;-)
