    <p>I'm uploading a tarball through a webpage, dropping it in to /tmp/ then asking this script (which will be invoked via crontab) to:</p> <p>1.) extract it</p> <p>2.) build a list of all of the files (only files and recursively) in the directory</p> <p>3.) search each file for a string and print that filename and line with matched string to a file.</p> <p>Everything is working up to the part where I want to build a list of files in the (extracted tarball) directory. If I <em>don't</em> put a "!" in front of the regex on line 6 in my code (matching only files that are .bak, .conf, .cfg), then I only get a dozen files in @filelist (as I'd expect, printed by the code on line 13). </p> <p>However, if I put a "!" in front of my regex on line 6 (intended to match everything <em>but</em> those files), line 13 will print all filenames, including files with .bak, .conf, and .cfg extensions.</p> <p>How can I get a collection of filenames in the (extracted tarball) directory except for those that I'm just not concerned about?</p> <p>This is my code, roughly (stripped down, untested.) I'm a perl newb so I apologize for the ugliness of what I have here but it is what it is.</p> <pre><code> 1 sub loadFiles { 2 my $dir=shift; 3 find(\&amp;recurDir,"$dir"); 4 } 5 sub recurDir { 6 if ( $File::Find::name =~ /(\.bak|\.conf|\.cfg)$/i ) { 7 push @filelist, $File::Find::name; 8 } 9 print "$File::Find::name\n"; 10 } 11 sub searcher { 12 my $file=$_; 13 print "Searching $file\n"; 14 } 15 my $tarball = '/tmp/mytarball.tar.gz'; 16 my $ae = Archive::Extract-&gt;new( archive=&gt;$tarball ) || die ("$!"); 17 $ae-&gt;extract( to=&gt;$UPLOAD_DIR ) || die ("$ae-&gt;error"); 18 my $dir_loc = File::Spec-&gt;catfile( $UPLOAD_DIR, $ae-&gt;files-&gt;[0]); 19 loadFiles("$dir_loc"); 20 find(\&amp;searcher, @filelist); </code></pre>

    1. COWhy you call 'find'? You can get list of files directly from tar-archive.

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.
