You are correct. The exit status of rsh is an indication of its own
successful or failing operation. It has nothing to do with the outcome of
the remote command. Typically, a trick like the following is used:
Status=`rsh -n -l <user> <remote-host> 'cksum <file> ; echo $?'`
if [ $Status -ne 0 ] ; then
<statements>
fi
