+    Since this is not very accurate, you might be interested to know how far back in the queue your job is. This can be accomplished with the following bash function:
+<pre>
+function qpos() {
+    if [ "$#" -eq 0 ]; then
+         squeue -u "$USER" | tail -n-1 | tr -s ' ' | cut -d' ' -f2 | while read jid; do
+            squeue | tr -s ' ' | cut -d' ' -f2 | sort -n | cat -n | grep "$jid"
+        done | tr -s ' ' | sort -n -t' ' -k1
+    fi
+    for jid in "$@"; do
+        squeue | tr -s ' ' | cut -d' ' -f2 | sort -n | cat -n | grep "$jid"
+    done
+}
+</pre>
+Usage:
+<pre>
+qpos
+</pre>
+    </p>
+</li>
 <li><p><code>scancel -i JOBID</code> to cancel the job.</p></li>
 <li><p><code>sinfo -pcompute</code> to look at available nodes.</p></li>
