OwnCloud add-on thread

So If I understand all, you connect to your ReadyNAs Duo with Putty (ssh) and you pull all lines before one by on.

In bash all line with # is a comment.

I explain the first 10 lines :

#!/bin/bash

-> it's to specify in a script the shell used, in our case bash, the one you have probably when you connect with you putty

cd /tmp

-> go in the /tmp directory

rm -Rf owncloud*.*

-> remove old download packet of ownCloud

#wget http://mirrors.owncloud.org/releases/owncloud-latest.tar.bz2

-> comment

wget http://mirrors.owncloud.org/releases/owncloud-4.5.5.tar.bz2

-> wget is a tool that download the owncloud packet at this url (to adapt at the version you wish (you have to do that with all patches from the original provide by the ReadyXtra add-on)

#rm -Rf /usr/share/owncloud_*

-> comment, before I removed the old backup instance of owncloud, but by security, : comment ;)

mv /usr/share/owncloud/ /usr/share/owncloud_save

-> we make a backup of our owncloud instance

#tar -xjf owncloud-latest.tar.bz2

-> comment

tar -xjf owncloud*.bz2

-> wu untar the download packet of owncloud

After that, when all it's ok, continue my instructions, if necessary I explain you the rest of the script later !
