Add the following content to your shell script editing session:</li></ol>

set centos1 centos2 centos3<br>for xwhile read line<br>

&nbsp;read -p "Enter regular username for \"$x\" server: " userName[$x]<br>&nbsp;ssh ${userName[$x]}@$x "cat /etc/network/interfaces" > /tmp/network-$x.$$<br><br>&nbsp;index=0 # load each line into an array for VM<br>&nbsp;while read line<br>&nbsp;do<br>&nbsp;&nbsp;&nbsp;$x[$index]="$line"<br>&nbsp;&nbsp;&nbsp;index=$(($index+1))<br>&nbsp;done < /tmp/network-$x.$$<br>done1<br>

 <ol><li value="6">Finally, we will generate a web-page document, use a loop to printout the results of the data (stored in an array) and open the Associative Arrays) web-page document in a report file called: /root/networkthe '''firefox''' web-info.txtThe command at the end is a trick to remove all temporary files that have the same extension as the current PID number, therefore, it is uniquebrowser.
