    <p>I am trying to figure out how to sort list of file names in Perl.</p> <p>Each file is a PDF file that I am merging into a single pdf using Perl's PDF::Reuse</p> <p>Each pdf file name has two unique identifier. 1) is the account ID &amp; 2) report type.</p> <p>Example:</p> <p>C1234.lfs.pdf</p> <p>C1234 = account id lfs = report type.</p> <p>each account could have several reports that need to be in a specific order. </p> <p>How can I specify the order of report types? I want to use a config file where the script would look to see what order to sort each accounts reports before merging to 1 pdf file. Order I would like is:</p> <p>AcctId.lau.pdf AcctId.lsm.pdf AcctId.lad.pdf AcctId.lfs.pdf AcctId.lbe.pdf</p> <pre><code>@PDFS = (&lt;*l*.pdf&gt;); @REVERSED_LIST = reverse(@PDFS); prFile($OutPut); for my $pdf (@REVERSED_LIST) { next if($pdf eq $OutPut); &amp;Logit("Adding $pdf to $OutPut"); prDoc($pdf); } prEnd(); </code></pre> <p>Sorry if I am not explaining this correctly any help and suggestions are appreciated.</p> <p>New code being tested not giving correct order.</p> <pre><code>@PDFS = (&lt;*l*.pdf&gt;); my %lsfOrder = (lua=&gt;0, lsm=&gt;1, lfw=&gt;2); @SORTED = map { $_-&gt;[0] } # Take just the original file name sort { $a-&gt;[1] cmp $b-&gt;[1] ? $a-&gt;[1] cmp $b-&gt;[1] : # compare by account id if different $lsfOrder{$a-&gt;[2]} &lt;=&gt; $lsfOrder{$b-&gt;[2]} } map { [ $_, split('.', $_) ] # split into id/type once at the beginning } @PDFS; prFile($OutPut); for my $pdf (@SORTED) { next if($pdf eq $OutPut); &amp;Logit("Adding $pdf to $OutPut"); #print "Adding $pdf to $OutPut\n"; prDoc($pdf); } prEnd(); </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.
