Title: Titchy Updater.sh Decoded?
Post by: ZDevil on October 18, 2007, 05:08:48 am

Hi,
Could someone decode the updater.sh from Titchy into a text file, please?
I badly need this to get access into the Debian ISO image to fix my root account setting, without being forced to reformat the disk before that.    
A million thanks in advance!

 On the Titchylinux site, if you poke around are three files that I found. Two of them are .py files that decode and encode the updater file. or so it says. The updater file is there also. I'm trying to attach them all now. Hope they help.   I'm obviously going to have to put a fake .deb on the end of them. The real name and type should be obvious.  

So just remove the .deb extension and you should be able to use them on your desktop to do what you want. I presume the process is decode, edit, encode and apply?

Cheers!

By the way, if the attachment bug bites, you can find them at the Neil's site if you wander about. I found them. On the Installing page, scroll down to the bottom of the screen and click on attachments. The files are there.  Take a bit of discovering though!

Must emphasize, the updater file I have uploaded is the original!

Thanks!  

Ok, now I would like to make a new updater.sh by disabling the automatic disk formatting actions.

Here is the full decoded updater.sh from titchy:

So my question is: Will it do to remove the lines from 107 to 130, i.e. starting from "echo '' echo 'Formatting microdrive...' ..." ?

Here is the attachment FYI.

 Glad you found the files of help. I think you may well be ok with stripping those lines you mention. But, being too lazy to count he lines, I'm not sure whether you mean to snip the ones below?

mount -t ext3 -o noatime /dev/${IDE1}1 /hdd1
if [ "$?" != "0" ]; then
   echo "Error!"
   exit "$?"
fi

Don't they mount the drive, which I think is essential?

Any way I'm sure there must be much more expert eyes watching this thread than mine. Good luck with it.  

You'll have noticed that I appear to have cured the powering up problem with 'Big Z', I think I'll adopt that name for the surgically enhanced little fellow!
