Getting exit code on the remote server after jump through a bastion

Question

I would like to get the exit code of my remote command. It's normally pretty easy, but I need to execute my command through a bastion host and I don't know take that with a easy methode. So, this is a diagram of my architecture. PC => Bastion => remote host I used this code to execute my command and check the return code: ssh -q -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -At ubuntu@$ip_bastion ssh -Aq -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null ubuntu@$ip_server bash <<EOF { ${cmd} ; } 2>&1 | sed -e 's/^/$(colors_next exec)$region:$ip:$type${normal} /' EOF echo $? if [[ $? -ne 0 ]]; then error "Error during the command execution." exit 1 fi But, the return code is always equal 0, while my command failed (Return 255 on the final server).

If you are using bash, you can use the PIPESTATUS array variable to get the exit status of each element of the pipeline. ssh -q -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -At ubuntu@$ip_bastion ssh -Aq -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null ubuntu@$ip_server bash <<EOF { ${cmd} ; } 2>&1 | sed -e 's/^/$(colors_next exec)$region:$ip:$type${normal} /' exit "\${PIPESTATUS[0]}" EOF remote_exitcode=$? echo "remote_exitcode=${remote_exitcode}" if [[ ${remote_exitcode} -ne 0 ]]; then error "Error during the command execution." exit 1 fi
