Adding script auto-upate

[GoogleCodeExporter]

It would be very useful, expecially for non-GUI appliances.

I'll need to find a way to detach a process from the script so that update runs 
smoothly.

Update process would then be :
Detect current build of the script
Use wget or curl to download the latest build and check it against the current 
one
If more recent, detach a process that would inject content of the new script to 
the current one.
Of course right after detaching this process we would exit torrentexpander.sh

This way we wouldn't have to deal with permissions...

... but I have no idea right now on how to do all that (especially the detach 
part)

Dirty code for NMT PLATFORM

$crontab=/etc/cront/root.cron
$path_torrentexpander_update_script=/share/Apps/Transmission/bin/torrentexpander
_update.sh

if [[ $auto_update == "yes" ]]; then
    already_planned = crontab -l | grep torrentexpander
    if [[ $already_planned == "" ]]; then
        echo '@reboot $path_torrentexpander_update_script >> $crontab'
    fi
fi

if [[ $auto_update == "no" ]]; then
 cat $crontab | sed 'g/@reboot $path_torrentexpander_update_script//s > $crontab
fi

Thanks for this
I'll do some tweaking... I'd really like to include auto update in the script 
without using cron

Another ideas:
torrentexpander create a script to autoupdating himself; it run 
torrentexpander_update.sh and ends. 
torrentexpander_update.sh take some time to ping google (we could use to very 
connection aslo!) while main program ends. 
Then the update starts.

if [[ $auto_update == "yes" && $is_outdated == "yes" ]]; then
    echo "#!/bin/sh
    ping -w 10 google.it;
    wget -o torrentexpander.sh http://torrentexpander.googlecode.com/svn/trunk/torrentexpander.sh
    chmod +x torrentexpander.sh
    " > torrentexpander_update.sh
    chmod +x torrentexpander_update.sh
    ./torrentexpander_update.sh
fi

I had something similar in mind
I'm pretty sure we can do this without creating a new script (on other 
platforms than the NMT, chmod +x may not work)
We can use something like screen to launch a command in a parallel process.
This update routine will be at the beginning of the script, right after 
torrentexpander knows what the torrent source and destination are.
This command will start by a 1 second pause, torrentexpander will exit, 
torrentexpander will be rewritten with the latest version of the script, then 
be relaunched with the path to the source and destination.
We'll use the settings to store current version of the script and the last 
updated at

In order not to have to increment version number of the script, I'll also try 
to parse this page for the SVN revision number
http://code.google.com/p/torrentexpander/source/browse/trunk

Thanks

Current SVN release has auto update built-in
Script will update daily, weekly, monthly or never, based on your settings.
In the future I may need to add a branch to the project so that the trunk 
release is exempt of any bug

New SVN build
I'm using a temp text file instead of a variable to store the new script
My NMT fucks up right now so I can't test it

Also, I added support for vi text editor, so you can directly edit your 
settings by using /path/to/torrentexpander.sh -c

Let me know if it works for you
