Body
<p>I have an interesting situation I am trying to script. I have a program that outputs 26,000 lines after 10 seconds when it starts successfully. Otherwise I have to kill it and start it again. I tried doing something like this:</p> <pre><code>test $(./long_program | wc -l) -eq 26000 && echo "Started successfully" </code></pre> <p>but that only works if the program finishes running. Is there a clever way to watch the output stream of a command and make decisions accordingly? I'm at a loss, not quite sure even how to start searching for this. Thanks!</p>

Guidance

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.
