Hey mentors, Firstly, thanks for all the help so far.
I like the idea of having a default copy of the file used by my program, as suggested by Lars and PJ, so I've altered my source code to use a default file and allow multiple users to have their own copies of this file in their home/<user>/Documents folder. "creating a default file in /usr/share and having the program copy it to the user's directory when it's run" However, I can't open a file from /usr/share via my python script as I don't have permission to open files in a protected directory, and after reading up a bit on it, it's been suggested that it's bad form to invoke super user in a script, as it's construed as a security risk (i.e. http://tldp.org/HOWTO/Security-HOWTO/file-security.html; http://www.velocityreviews.com/forums/t346075-sudo-open-python-newbee-question.html) Do I really have to use sudo or super user privileges to just open and copy a text template? Where do packagers normally install files of this type? I thought it might be a good idea to store it in home/<user>/.<packageName> But I'm still at a loss as to how I can find a users home directory from the rules makefile :( been trying to use ~/ and $XDG_CONFIG_HOME but I just end up with everything being installed in folders called "~" or "DG_CONFIG_HOME" Here's the source code if you need more info: #!/usr/bin/python # Code Name: gtk-link-lizard # Created By: Jim Frize, <http://sonodrome.co.uk> # Copyright (C) 2011 Jim Frize, <j...@sonodrome.co.uk> # Licence: GTK Link Lizard is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
