Set default shell to ksh in Void Linux

Changed my default shell to match OpenBSD and to avoid bashisms whilst I'm learning to write scripts.

$ chsh void
Changing shell for void.
Password: 
New shell [/bin/bash]: /bin/ksh
Shell changed.
$_

A script to find IP addresses of hosts on my network

#!/usr/bin/bash
# Find hosts on LAN
# Edit variables to suit your needs

typeset -i i

echo -e "\nPinging addresses 1 to 255\n"
for (( i = 1 ;  i<255 ; i++ )) ;
             do
             ip=$NETWORK.$i
             ping -c 1 -W $SECS $ip >/dev/null
        if [ $? == '0' ]
            then
            echo $ip exists
        fi
    done
