<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The above while loop assumes that your allow.list has only one item on each line which is in fact a remote address in the form you expect (e.g. one, two, three,
four, five etc…) The default separator for the while is white space so if you did have multiple items per line and only wanted the first one on the line you have to set two variables – it will assign the first item on the line to the first variable and everything
else the next variable (which can then be ignored in the rest of the script.) Similarly if you had 4 (or more) items per line and wanted the first and third you’d have to set 4 variables so it would assign the first 3 items to their own variables and the
remaining to a final variable. Here again you can use the first and third variables in the script and ignore the second and fourth.<o:p></o:p></span></p>

The script below shows a variety of attempts. <br>

Ultimately, we're aiming to grab the list from a file, eg "LIST="`cat allow.list`"<br>
