    <p>I have the following minimal source file:</p> <pre><code>$ cat path/xx/yy/fooBar.c void this_is_a_test(void) { } </code></pre> <p>If I run etags like this it works ok:</p> <pre><code>$ etags path/xx/yy/fooBar.c $ cat TAGS path/xx/yy/fooBar.c,25 void this_is_a_test(1,0 </code></pre> <p>But if I run etags via find/xargs the TAGS file is corrupted:</p> <pre><code>$ find . -name fooBar.c ./path/xx/yy/fooBar.c $ find . -name fooBar.c | xargs etags $ cat TAGS path/xx/yy/fBoBar.c,25 void this_is_a_test(^?1,0 </code></pre> <p>Note the filename shows up above as fBoBar.c -- bogus!</p> <p>I like to be able to generate TAGS by doing something like <code>find . -name '*.[ch]' | xargs etags</code>. But it is corrupting most of the filenames when I do this.</p> <p>Any idea why it is failing like this, and/or what I can do to make it work?</p> <p>Ubuntu Lucid. Etags is from emacs23-bin-common 23.1+1-4ubuntu7.</p> <p><strong>Edit</strong>:</p> <p>In response to fschmitt's question:</p> <pre><code>$ etags $(find . -name fooBar.c) $ cat TAGS path/xx/yy/fBoBar.c,25 void this_is_a_test(1,0 </code></pre> <p><strong>New info</strong>:</p> <p>I just noticed that the difference between the two uses in my original question above is the leading <code>.</code> on the path. And if I call etags like <code>etags ./path/xx/yy/fooBar.c</code>, it corrupts the file. So a workaround is to make sure the args to etags don't have leading tags. (Perhaps this is a bug in etags, because the documentation describes my usage pattern almost exactly.)</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.
