GUI Updates script

[anon222]

Some nice additions there misko I think we should remove the checklist though, new folk could interrupt this incorrectly.

OK, checklist is removed
Some minor improvements to the script.
First open sinaptic and/or gdebi-gtk to test this.

Code:

exit 0

Here you've used the title to give info on the next step

Code:

zenity --text-info --title="List of available Updates - Click OK to continue or Cancel to stop the update process" --width=700 --height=300 --filename="/tmp/updateslist "

There is another approach
I've used stream editor in the script to insert two lines into /tmp/updateslist

Code:

#Insert text into  /tmp/updateslist
sed -i -e '1 i\#########                     List of available Updates                                           ##############' -e '1 i\#########  Click OK to continue or Cancel to stop the update process         ##############' /tmp/updateslist
