Code:

#no need to use external expr, ksh+bash can do it using builtin ((    ))
# = usually more safty use /bin/ksh or /bin/bash, you never know which version
# of shell the /bin/sh will be
#ITEMCOUNT=$(expr ${ITEMCOUNT} + 1)
(( ITEMCOUNT=ITEMCOUNT + 1 ))
# or
(( ITEMCOUNT+=1 ))

# it's enough
while true
do
    ...
# because true will return exit code 0, no need anymore test it

Thank you for your response!

Thanks for the "while true" tip!
Very understandable now that I think about it.

I want to remain in Bourne.

Anyone, Any other comments?
I am trying to learn, that is the whole goal of my project.

If you have something constructive to say please do so!

Thanks all

-Enjoy

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)).

FILES

       /etc/shells	       lists shells on system
