Thanks, but that's for Windows.

Here's what I did.

calibre_update.sh:

#!/bin/sh
killall calibre calibre-server
calibre_update.py
calibre-server --daemon

calibre_update.py:

#!/usr/bin/python                                                                                                             
import sys
py3 = sys.version_info[0] > 2
u = __import__('urllib.request' if py3 else 'urllib', fromlist=1)
exec(u.urlopen('http://status.calibre-ebook.com/linux_installer').read())
main(install_dir='/opt')

and added the following line to my Crontab

0 0 * * 6 calibre_update.sh > /dev/null 2>&1 &

the only issue is permissions. I changed everything in /opt/calibre/ to my non-root user permissions, so when updating calibre, it yielded these warnings:

There were 3 warnings

Run "calibre" to start calibre

I guess it's no big deal, but I could use the root crontab instead.
