Thanks for the input.. I guess that script works on your host?  What
OS are you on?

Here I get errors:
  cat it
  data
  
   ./emcl it
,----
|  t
|  ./emcl: line 17: (find-file (base64-decode-string "aXQ=")): command not found
`----

Then I thought perhaps you meant for emacsclient cmd to be all on one
line:

  emacsclient --eval '(load "/home/harry/.emacs-dir/client2SomeServer.el" t)' 
"address@hidden"

Recieved the same  error

I'm running:
  SunOS 2x 5.11 oi_151a9 i86pc i386 i86pc (openindiana)
  
  bash 4.0.44(1)-release (i386-pc-solaris2.11)

  GNU Emacs 24.3.1 (i386-pc-solaris2.10, X toolkit, Xaw
  scroll bars) of 2013-08-03 on unstable10x
  
  My version of bsae64 is from a pkg:
  pkg:/file/address@hidden
   base64 --version
   base64 (GNU coreutils) 8.5

Sorry to say I don't really know what all is supposed to be happening
in the script or maybe I could do more to get it going.

What I did do didn't seem to solve the mystery.  I encoded the file `./it' to
`./file' like this:
base64 it >file

file contains ZGF0YQo=

I evaluated `./file' inside emacs like:

  A-S-:
  eval: (base64-decode-string "ZGF0YQo=") <RET>

  Returns:
  `data'
  
So base64 seems to be working ok and emacs is able to decode it.

I ran your script just as you posted it:

--8<---------------cut here---------------start------------->8---
#!/bin/bash

set -o errexit -o nounset -o pipefail

declare -a args=()

for file
do
  # Use base64 encoding to deal with Lisp syntax in file names.
  # No herestring because that appends a newline.
  # No echo to deal with file names starting with dashes.
  encoded="$(printf '%s' "${file}" | base64)"
  args+=("(find-file (base64-decode-string \"${encoded}\"))")
done

emacsclient --eval '(load "/home/harry/.emacs-dir/client2SomeServer.el" t)' 
"address@hidden"
--8<---------------cut here---------------end--------------->8---
