    <p>For Perl one-liners, when using the <code>-p</code> or <code>-n</code> flags is it possible to make the <code>END {}</code> block execute once per file, instead of only once for the entire program?</p> <p>In other words, when I write:</p> <pre><code>perl -ne '$count++ if/.../; END {print "$ARGV: $count" if $count &gt; 0}' mysourcedir/*.html </code></pre> <p>I'd like to execute the END block once for each file, instead of just once globally at the end of the program's execution. </p> <p>Currently I just use xargs for this, but wondered if Perl maybe had some alternate flag for that behavior.</p> <pre><code>echo mysourcedir/*.html | xargs -n1 perl -ne '$count++ if/.../; END {print "$ARGV: $count" if $count &gt; 0}' </code></pre> <p>PS - in case you're wondering why I don't just just <code>grep | wc -l</code> for this simple case, it's because this example is simplified from my real use case, which involves both incr (++) as well as decr (--) in the tally</p> <hr> <p>Answer: Based on @mpapec's technique, plus a small tweak to also reset the $count var per file, I get this which works: </p> <pre><code>perl -ne '$count++ if/.../; if (eof &amp;&amp; $count &gt; 0) {print "$ARGV: $count"; $count = 0;} ' mysourcedir/*.html </code></pre>

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.
