    <p>One problem may be that your <code>wget</code> creates a file regardless of whether there's a source file so checking for existence will always be true.</p> <pre><code>if [ -s $TMPNAMED ] then echo "done." # file exists AND has data else echo "no new data!" exit fi </code></pre> <p>will test to see if it's empty or non-existent and exit if so. This may be an issue with your <code>if [ -e $ZONELOCATION/$ZONE.db ]</code> as well.</p> <p><code>sed</code> or <code>awk</code> could do all of this in one line:</p> <pre><code>grep "^zone" $TMPNAMED | cut -d " " -f "2" | cut -d "\"" -f 2 &gt; $TMPZONEFILE sed '1,5d' $TMPZONEFILE &gt; $TMP </code></pre> <p>but I would need to see some sample data to offer a solution.</p> <p>Simplified quoting:</p> <pre><code>echo "done. ($TMPZONEFILE)" </code></pre> <p>You're not using the <code>IGNORE</code> variable or the <code>updates</code> variable. I don't see any reason to export it. Also, if you are relying on it elsewhere, its value won't survive once the <code>while</code> loop exits since piping something (<code>grep</code> in this case) into <code>while</code> sets up a subshell. It may be better to do one of these:</p> <p>Bash:</p> <pre><code>while ... do ... done &lt;(grep -vf ignore.txt $TMPZONEFILE) </code></pre> <p>sh:</p> <pre><code>grep -vf ignore.txt $TMPZONEFILE &gt; tmp.out while ... do ... done &lt; tmp.out </code></pre> <p>I recommend using <code>mktemp</code> or <code>tempfile</code> to create temporary files, by the way.</p> <p>This might be more readable and allows you to include quotes without having to escape them:</p> <pre><code>cat &lt;&lt; EOF &gt;&gt; "$NAMED" zone "$ZONE" { type slave; file "$ZONELOCATION/$ZONE.db"; masters { 91.121.75.205; }; allow-notify { 91.121.75.205; }; }; EOF </code></pre> <p>It's always a good habit to quote variables that contain filenames.</p>

    1. COThis is very explanitory, I'm going to have to work through it and tes the methods you've outlined and see how it goes. I am very new to scripting in linux and have never really learned anything more than what I had to do and that worked.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
