    <p><strong>UPDATED</strong></p> <p>Try something like this (OP's code modified a little bit):</p> <pre><code>#!/usr/bin/bash stop() { [ $CPID -ne 0 ] &amp;&amp; kill -INT $CPID &amp;&amp; wait $CPID &amp;&amp; echo "Killed $CPID"; } trap "stop; exit" INT CPID=0 while :; do read -p "Enter your number here: " YOURNUMBER stop [ "$YOURNUMBER" == quit ] &amp;&amp; break; TIMESTAMP=$(date +"%Y.%m.%d_%H.%M") avconv -f video4linux2 -r 3 -fs 52428800 -i /dev/video0 /home/$USER/orders/$YOURNUMBER/$TIMESTAMP-$YOURNUMBER.avi&amp; CPID=$! echo -e "Video complete!" done </code></pre> <p>This starts <a href="/questions/tagged/avconv" class="post-tag" title="show questions tagged 'avconv'" rel="tag">avconv</a> in the background so the user can enter a new number. Maybe the stdout and stderr of <a href="/questions/tagged/avconv" class="post-tag" title="show questions tagged 'avconv'" rel="tag">avconv</a> should be redirected to a log file or to /dev/null. Also it should be tested which signal stops <a href="/questions/tagged/avconv" class="post-tag" title="show questions tagged 'avconv'" rel="tag">avconv</a> gracefully. <code>-INT</code> is equivalent to ctrl+c. It it does not work, try <code>-HUP</code>, <code>-TERM</code> or even <code>-KILL</code> if nothing else helps. Maybe You should implement a <code>trap</code> to catch <code>INT</code> signals to kill the last <a href="/questions/tagged/avconv" class="post-tag" title="show questions tagged 'avconv'" rel="tag">avconv</a> it ctrl+c is pressed.</p>

    1. COAlmost there! Thank you! Only thing is that I (or the end user) has to enter the number twice before it starts recording it again.. How do I implement the trap? (Sorry, literally my first couple of days at this whole thing - quite fun though!)

    2. CO"INT" signal stops `avconv` fairly gracefully, so maybe you should sleep some seconds after kill.

    3. COIs that literally just sleep 5 or similar? Also, where does that go (sorry, I'll understand eventually!)

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.
