It's because not all your files are under /opt/dba/scp/. Check your list file and tell me, which ones should be converted from (whatever)/filename into /opt/dba/scp/filename, and which ones should be left as-is?

Or can they all be left as-is? In that case:

Code:

while read fname; do 
    #bname=$(basename $fname) 
    echo "trying ${fname}" >&2

    hash=$(/usr/local/bin/md5 "$bname" | awk '{print $4}')

    echo "local hash is ${hash}" >&2

    # should just print the md5's
    /usr/local/bin/hosts | while read box
    do
        T=$(ssh ${box} "/usr/local/bin/md5" "$fname" | awk '{ print $4;}')
        [ "$T" = "$hash" ] || echo "${box} $fname differs!"
    done

done < /home/izivanov/iz3

As for the syntax errors, ordinarily i'd try shell code I post on my own system before offering it to you but that's impossible for this script...
