Array output through a for loop problematic with multiple elements.
This code works perfect when using a machine with only one interface online. (Excluding the loopback of course) But when I have other interface up for vmware or a vpn the output gets mixed up. I know I had this working when I was just reading ip's from files so I know it is not a problem with nmap, even though it feeds back the error. Any help much appreciated.

Code:
#!/bin/bash

x=5.21

zero+=( "$(/sbin/ifconfig | grep "inet addr" | awk '{ print $2 }' | sed -e '/127.0.0.1/d' | cut -c6- | sed 's/.[^.]*$//' | uniq)" )

v=`nmap --version | grep "Nmap" | awk '{ print $3 }'`


for i in "${zero[@]}"
do
        if [ $v == $x ]; then
                one+=( "$(nmap -sP $i.0/24 | grep report | awk '{ print $5 }')" )
                sleep 1
        else
                one+=( "$(nmap -sP $i.0/24 | grep Host | awk '{ print $2 }')" )
                sleep 1
        fi
done

y=0
length=${#one[@]}
for (( z = 0; z < $length; z++ ));
do
    echo -e "${one[$y]}\n"
done

By the way. I have only tested this with nmap 5.00 and 5.21. It may not work at all on other versions.

xsetpointermapping

XSetPointerMapping(3X11)					  XLIB FUNCTIONS					  XSetPointerMapping(3X11)

NAME

       XSetPointerMapping, XGetPointerMapping - manipulate pointer settings

SYNTAX

       int XSetPointerMapping(display, map, nmap)
	     Display *display;
	     unsigned char map[];
	     int nmap;

       int XGetPointerMapping(display, map_return, nmap)
	     Display *display;
	     unsigned char map_return[];
	     int nmap;

ARGUMENTS

       display	 Specifies the connection to the X server.

       map	 Specifies the mapping list.

       map_return
		 Returns the mapping list.

       nmap	 Specifies the number of items in the mapping list.

DESCRIPTION

       The XSetPointerMapping function sets the mapping of the pointer.  If it succeeds, the X server generates a MappingNotify event, and XSet-
       PointerMapping returns MappingSuccess.  Element map[i] defines the logical button number for the physical button i+1.  The length of the
       list must be the same as XGetPointerMapping would return, or a BadValue error results.  A zero element disables a button, and elements are
       not restricted in value by the number of physical buttons.  However, no two elements can have the same nonzero value, or a BadValue error
       results.  If any of the buttons to be altered are logically in the down state, XSetPointerMapping returns MappingBusy, and the mapping is
       not changed.

       XSetPointerMapping can generate a BadValue error.

       The XGetPointerMapping function returns the current mapping of the pointer.  Pointer buttons are numbered starting from one.  XGetPoint-
       erMapping returns the number of physical buttons actually on the pointer.  The nominal mapping for a pointer is map[i]=i+1.  The nmap argu-
       ment specifies the length of the array where the pointer mapping is returned, and only the first nmap elements are returned in map_return.

DIAGNOSTICS

       BadValue  Some numeric value falls outside the range of values accepted by the request.	Unless a specific range is specified for an argu-
		 ment, the full range defined by the argument's type is accepted.  Any argument defined as a set of alternatives can generate this
		 error.
