I believe it is.

Right. That is where screen comes in. Unless you have more output than
screen's buffer will keep (see the '-h' flag to change that).

The good thing about screen is that you immediately see if the task is still
running and if and with which error it finished.

You need to redirect stderr ...

        % command >& /some/file

... or in case you really mean "piping" ...

        bash% command 2>&1 | second_command
        csh%  command |& second_command

Holger
