    <p>I often use the excellent <a href="http://www.gnu.org/software/findutils/manual/html_mono/find.html" rel="noreferrer">find</a> program in Bash to list files with certain filters. For example, in a Subversion (SVN) working copy, I sometimes wish to recursively list all files but excluding the <code>.svn</code> subdirectories as follows:</p> <pre><code>find . -name '.svn' -prune -o -type f -print </code></pre> <p>Today, I wanted to do something similar, but I also wanted to affect the order in which directory contents were listed: I wanted 'ordinary' files to be followed by sub-directories (and then the recursive contents). There does not appear to be an option for this.</p> <p>The <a href="http://www.gnu.org/software/coreutils/manual/html_node/ls-invocation.html" rel="noreferrer">ls</a> (list) command has an option to list recursively. This command has many sorting options, including list by file name, access time, size, and so on, but not classification, although the <code>-p</code> option will annotate directories.</p> <p>Now, I <em>could</em> write, e.g., a Python script to do exactly what I want. However, <code>find</code> already does almost everything I want. Usually within a Bash shell, it is possible to combine programs to do just what you want: each program, like <code>find</code>, <code>sort</code>, <code>uniq</code>, <code>ls</code>, <code>wc</code>, performs a simple task, but does so well. Not every program needs to be able to sort because <code>sort</code> can sort. So, really, I'm just curious...</p> <p><strong>My question is, do you know if there's a way to do what I want: to both filter and sort a recursive file listing, just by combining Bash programs?</strong></p> <p>For example, <code>find</code> gives me the files in this, alphabetical, order:</p> <pre><code>a.txt b\file1.txt b\subdir\file2.txt b\then_file3.txt c.txt d\file4.txt e.txt </code></pre> <p>but I'd prefer them in this order, where within each directory, the ordinary files are listed alphabetically first, followed by the directories, again alphabetically:</p> <pre><code>a.txt c.txt e.txt b\file1.txt b\then_file3.txt b\subdir\file2.txt d\file4.txt </code></pre> <p>(I am a Windows user, but I run a Bash shell in <a href="http://www.cygwin.com/" rel="noreferrer">Cygwin</a>.)</p> <p>Thanks.</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.
