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

You can assign the exit status to a variable as simple as doing:

variable=$?

Right after the command you are trying to inspect. Do not echo $? before or the new value of $? will be the exit code of echo (usually 0).
