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...

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).
