    <p>My title is a bit confusing because I don't know how to express it in good english.</p> <p>Here's my issue. I'm having a flat file formatted this way: </p> <pre><code>: name1 field1-1: field2:value1-2 field3:"value1-3" field4:{"Value-1-4"} : name2 field2-1: field2:"value2-2" field4:{"Value-2-4"} field3:Value2-3 : name3 field3-1: field3:{"Value-3-3"} field2:value3-2 field4:value3-4 </code></pre> <p>So you can see that it's not a nice file because field does not appear in the same order they can be with different type of value sometimes and more over they are sometime missing. The orginal file is also 5 to 20 fields long. </p> <p>Now here's what I want to have in the end: </p> <pre><code>: name1 field2:value1-2 field4:{"Value-1-4"} : name2 field2:"value2-2" field4:{"Value-2-4"} : name3 field2:value3-2 field4:value3-4 </code></pre> <p>So I know the field I want in the final file and I know the precise order I want them to appear.</p> <p>I tried something like </p> <pre><code>sed "s/(field1:.*)|(field2:.*)/\2\1/g" </code></pre> <p>I know it's not the right synthax but it's for readability. But it do not work because the first match is the only to match that happen and the other group can't match. </p> <p>I guess what I want to do is possible with a lot of <code>awk</code>, but I really don't know how I can do it. I really prefer to use <code>bash</code>, <code>sed</code>, <code>awk</code> and <code>grep</code> but if I have no choice I can I can deal with a bit of <code>Perl</code></p> <p><strong>EDIT:</strong> I may give a simple example but the real file has really different fields name</p> <p>Good night and thank you </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.
