    <p>I'm having real issues getting an external script to run from my Java application on OS X 10.8. It works on Windows, so not sure what I'm doing wrong for OS X.</p> <p>What works (Windows):</p> <pre><code>String[] commands = { "\"" + _appDataDir + "\\Temp\\Workers\\" + _batchName + "\"", "\"" + _appDataDir + "\\Temp\\frame%d.jpg\"", "\"" + _fileName + "\""}; proc = rt.exec(commands); </code></pre> <p>So I have the following for OS X:</p> <pre><code>String[] commands = { _appDataDir + "/Temp/Workers/" + _batchName, _appDataDir + "/Temp/Workers/mac-ffmpeg", _appDataDir + "/Temp/frame%d.jpg", "\"" + _fileName + "\""}; proc = rt.exec(commands); </code></pre> <p>This works when there are no spaces in the filename, but fails when there are spaces with a "java.io.IOException: Bad file descriptor" error.</p> <p>At the moment, I've changed all the paths to have no spaces as an easy fix, but I don't have control over the fileName string as this is selected by the user from a save dialog. I've tried with and without double quotes around fileName but neither make any difference.</p> <p>I also tried ProcessBuilder as below (both with and without the "/bin/bash/, -c" bits):</p> <pre><code>ProcessBuilder proc2 = new ProcessBuilder( "/bin/bash", "-c", _appDataDir + "/Temp/Workers/" + _batchName, _appDataDir + "/Temp/Workers/mac-ffmpeg", _appDataDir + "/Temp/frame%d.jpg", "\"" + _fileName + "\"" ); proc = proc2.start(); </code></pre> <p>but this gives the same error. As far as I can tell I'm doing everything that's being suggested in other similar questions, but nothing is working. Any ideas would be appreciated!</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.
