linux - commands in bash script doesn't work properly -


i have script :

#!/bin/bash ./process-list $1  det=$? echo $det if [ $det -eq 1 ]    echo "!!!"    ssh -n -f 192.0.2.1 "/usr/local/bin/sshfs -r 192.0.2.2:/home/sth/rootcheck_redhat /home/ossl7/r"    rk=$(ssh -n -f 192.0.2.1 'cd /home/s/r/rootcheck-2.4; ./ossec-rootcheck >&2; echo $?' 2>res) if [ $rk -eq 0 ]    echo "not!"  fi fi exit;

i ssh system 192.0.2.1 , run sshfs command on it. actualy want mount directory of system 192.0.2.2 on system 192.0.2.1 , run program (which located in directory) on system 192.0.2.1. these ssh , sshfs commands work properly. when run them manually , output of program ossec-rootcheck written file res ,but when run script, mount done no output written file res. guess program ossec-rootcheck runned don't know why output isn't written! script used work before don't know happend suddenly!

as far understand program, remote machine has stdin>stderr, how local machine ssh being evaluated?

the end ' means on rk= line, 2>res happens locally. (and there no error ssh, remote error, if any, lost when ssh completes.) try >res whatever ssh prints out, unfortunately including non-errors.
