Calibre Autoupdater for Linux

[LeonGaultier]

Hi

I have wrote a small shell script for Linux which Calibre Updated automatically when a new version is available. Thought so now it is time to share the part with the world.

git clone https://code.google.com/p/calibre-autoupdate/

Thank you for sharing with the calibre community. Now we have OSX, Windows and Linux covered by a user supplied auto-updater script.

What is wrong with Kovid's one-liner?

There is a calibre-upgrade.sh here

(the old version has been kept up for backwards compatibility, but we wouldn't be in this thread if we were content with plebeian methodologies. )

#!/bin/bash

calibre-debug -c "import urllib as u; from calibre.constants import numeric_version; raise SystemExit(int(numeric_version  < (tuple(map(int, u.urlopen('http://calibre-ebook.com/downloads/latest_version').read().split('.'))))))"

UP_TO_DATE=$?

if [ $UP_TO_DATE = 0 ]; then
	echo "Calibre is up-to-date"
else
	calibre --shutdown-running-calibre
	killall calibre-server

	sudo -v; wget -nv -O- https://github.com/kovidgoyal/calibre/raw/master/setup/linux-installer.py | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"
fi

And we have more goodies, like calibre-uninstall, and an "isolated" updater.

This will check for an updated version, and then it is a simple matter of running calbre-upgrade.sh in a weekly cron job. It compares calibre --version to the website version, and calls Kovid's one-liner. Nice and simple. Why didn't we make a sticky for that anyway?

If you had separated that info out from the 3 page thread it certainly could have been made a sticky. In case you missed it I'm clueless when it comes to Linux.

How about starting a thread with the Updater, calibre-uninstall, and an "isolated" updater you mentioned with an appropriate title and I'll be glad to give you the official reigns of the Linux sticky.

Oh, I was reprimanding myself for not pursuing the point at the time, I kinda forgot.

I created a thread here: https://www.mobileread.com/forums/sho...d.php?t=237233, describing the process. Can you sticky it?

The Script is not only for update. You can install Calibre first time or deinstall it.

New Version is out v0.14

calibre has a bundled uninstaller, and the simple update script will upgrade from version=none, as well, since that also causes the version check to fail to return a up-to-date.

This just looks kind of complicated, when all you really need to do is run Kovid's installer with a cron job.

Unless there is some extra benefit I couldn't see? Your scripts are in German, so it was kind of difficult to follow the variable names and I couldn't read the comments. But it looked like you were duplicating Kovid's script and not much else.

Also, you were using sed and grep to find the current and latest versions somehow? It can be done simpler, as I demonstrated, using calibre-debug to report on itself, and using the page http://calibre-ebook.com/downloads/latest_version instead of parsing the download redirect.
