shell script ssh command exit status

Question

In a loop in shell script, I am connecting to various servers and running some commands. For example

#!/bin/bash
FILENAME=$1
cat $FILENAME | while read HOST
         


        

Answer 1

An interesting approach would be to retrieve the whole output of each ssh command set in a local variable using backticks, or even seperate with a special charachter (for simplicity say ":") something like:

export MYVAR=`ssh $HOST 'echo -n ${HOSTNAME}\:;pwd'`

after this you can use awk to split MYVAR into your results and continue bash testing.
