    <p><code>sys.exit(myString)</code> doesn't mean "return this string". If you pass a string to <a href="http://docs.python.org/library/sys.html#sys.exit" rel="nofollow noreferrer"><code>sys.exit</code></a>, <code>sys.exit</code> will consider that string to be an error message, and it will write that string to <code>stderr</code>. The closest concept to a return value for an entire program is its <a href="https://en.wikipedia.org/wiki/Exit_status" rel="nofollow noreferrer">exit status</a>, which must be an integer.</p> <p>If you want to capture output written to stderr, <a href="https://stackoverflow.com/questions/3130375/bash-script-store-stderr-in-variable">you can do something like</a> </p> <pre><code>python yourscript 2&gt; return_file </code></pre> <p>You could do something like that in your bash script</p> <pre><code>output=$((your command here) 2&gt; &amp;1) </code></pre> <p>This is not guaranteed to capture only the value passed to <code>sys.exit</code>, though. Anything else written to stderr will also be captured, which might include logging output or stack traces.</p> <p>example:</p> <p>test.py</p> <pre><code>print "something" exit('ohoh') </code></pre> <p>t.sh</p> <pre><code>va=$(python test.py 2&gt;&amp;1) mkdir $va </code></pre> <p><code>bash t.sh</code></p> <p><em>edit</em></p> <p>Not sure why but in that case, I would write a main script and two other scripts... Mixing python and bash is pointless unless you really need to.</p> <pre><code>import script1 import script2 if __name__ == '__main__': filename = script1.run(sys.args) script2.run(filename) </code></pre>

    1. COThis all works. But I'd advise to use integer exit codes to allow the script to play nice in a Un*x environment.

    2. COUhm. Why are you doing `2>`? what's that `2` for? All I need to do is to retrieve the location of a file that my python script has created and written to and I can't turn off all prints.

    3. CO`>` is a redirection operator. `2>` redirect error messages, `>` alone is stdout `<` is stdin

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
