Yes, rsh doesn't transfer the exit status of the remote command
to the local machine.
ssh does, so if that's an option you may want to switch.
Otherwise, you may do instead of
rsh somehost '/path/to/my_server'
echo "Exit status was $?"
(which in that case returns 0 unless *rsh* fails)
{
status=$(
rsh somehost '
/path/to/my_server >&2
echo "$?"
'
)
} 2>&1
echo "Exit status was $status"
As rsh opens two channels, one for stdout, one for stderr. The
above makes all the stdout and stderr go to the local stdout so
that the remote stdout can be used to carry the exit status.
This assumes that the user who is executing this has a
Bourne-like shell as its login shell on the remote host.
