return code

Боюсь что единственный метод это на удаленной машине вместо программы запускать скрипт которые запускает программу и печает код возврата на терминал. А скрипт в котором необходимо проверить код возврата должен обработать эту ситуацию. Давно было дело, но както сталкивался со скриптом ersh которые собсвенно делал все необходимое. Поищи может найдешь. Удачи.

Кажется нашел реализацию выше сказанного. Новость 1993 года поэтому поищи может что более новое появилось...

ersh is a front end to rsh which returns the exit status of the remote command,
or 99 if the connection is broken prematurely. If ersh is invoked without a
remote command, rlogin is invoked. Usage is the same as rsh(1).

ersh 3.0, posted to alt.sources by Maarten Litmaath on 4 June 91, did
not handle the -n flag correctly:

When the usage "ersh [ flags ] hostname [ command ]" was used, "-n" was not
recognized as a flag unless it was preceded by the "-l username" flag.

When the usage "ersh hostname [ flags ] [ command ]" was used, "-l" was not
recognized as a flag if the "-n" flag preceded it.

The following version of the ersh script corrects these problems:

# This rsh front-end returns the exit status of the remote command,
# or 99 if the connection is broken prematurely.
# It works OK with sh/csh-compatible shells on the remote (!) side.
# If there is no remote command present, rlogin is invoked, which
# need not return a meaningful exit status.
# Usage: see rsh(1).

Bolshoe spasibo za pomosh!

Ja sdelal tak kak wi posowetowali:

set rcode='rsh "jupiter scr2 | tail -1"'
a w scr 2 pered exit ja napisal:
echo 15

Eshe raz spasibo!
