    <p>It depends on (a) how attached you are to the number 7 as opposed to, say, Lemons, and (b) whether any of your file names contain newlines (and whether you're willing to rename them if they do).</p> <p>There are many ways to deal with it, but some of them are:</p> <pre><code>mplayer Lemon*.mp3 find . -name 'Lemon*.mp3' -exec mplayer {} ';' i=0 for mp3 in *.mp3 do i=$((i+1)) [ $i = 7 ] &amp;&amp; mplayer "$mp3" done for mp3 in *.mp3 do case "$mp3" in (Lemon*) mplayer "$mp3";; esac done i=0 find . -name *.mp3 | while read mp3 do i=$((i+1)) [ $i = 7 ] &amp;&amp; mplayer "$mp3" done </code></pre> <p>The <code>read</code> loop doesn't work if file names contain newlines; the others work correctly even with newlines in the names (let alone spaces). For my money, if you have file names containing a newline, you should rename the file without the newline. Using the double quotes around the file name is key to the loops working correctly.</p> <p>If you have GNU <code>find</code> and GNU <code>xargs</code> (or FreeBSD (*BSD?), or Mac OS X), you can also use the <code>-print0</code> and <code>-0</code> options, as in:</p> <pre><code>find . -name 'Lemon*.mp3' -print0 | xargs -0 mplayer </code></pre> <p>This works regardless of the contents of the name (the only two characters that cannot appear in a file name are slash and NUL, and the slash causes no problems in a file path, so using NUL as the name delimiter covers everything). However, if you need to filter out the first 6 entries, you need a program that handles 'lines' ended by NUL instead of newline...and I'm not sure there are any.</p> <p>The first is by far the simplest for the specific case on hand; however, it may not generalize to cover your other scenarios that you've not yet listed.</p>

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.
