+Sort jails  
+----------
+Use -s switch followed by sort criteria. Criteria is a field name, prefixed with + or - for sort order (increase/decrease):  
+<pre><code>
+gocage list -f Config.Boot=1,Running=true -o JID,Name,Running,Config.Boot -s +JID
++=====+==========+=========+=============+
+| JID | Name     | Running | Config.Boot |
++=====+==========+=========+=============+
+| 22  | srv-dns1 | true    | 1           |
++-----+----------+---------+-------------+
+| 29  | bdd-tst  | true    | 1           |
++-----+----------+---------+-------------+
+| 183 | test     | true    | 1           |
++-----+----------+---------+-------------+
+</pre></code>
+
+You can use up to 3 criteria, delimited with comma:  
+<pre><code>
+gocage list -f Config.Boot=1,Running=true -o JID,Name,Running,Config.Boot -s +JID,+Name  
++=====+==========+=========+=============+
+| JID | Name     | Running | Config.Boot |
++=====+==========+=========+=============+
+| 22  | srv-dns1 | true    | 1           |
++-----+----------+---------+-------------+
+| 29  | bdd-tst  | true    | 1           |
++-----+----------+---------+-------------+
+| 183 | test     | true    | 1           |
++-----+----------+---------+-------------+
+</pre></code>
+
+OK the example is shitty as JID are unique. But this work, trust me!
