Zenity Script Help for getvirtualbox.

[Texstar]

Let me preface this by saying that bash scripting is not my strong suite. Here is a working bash script that will download and install Virtualbox 3.2.2 Non OSE edition with USB support. I need someone to help convert it to a zenity script so we can add it as a package to the repository as GetVirtualBox. Something similar to what we do for GetOpenOffice. If Oracle won't make a PCLinuxOS  prebuilt rpm like they do for other distributions then we will provide a way to get the Non OSE version installed for our members.

Thanks for any help on this.

I'll have a look and see if I can do anything. (And keep my fingers crossed that someone better at this comes along to help. )

If Oracle won't make a PCLinuxOS  prebuilt rpm like they do for other distributions then we will provide a way to get the Non OSE version installed for our members.

What can I say! Tex, you're a Diamond Geezer!!

==================================

Edit: I run the script on a clean install and it went fine.

Only one error message  (full Konsole output on attached txt file)

Verifying archive integrity... All good.

The python script error is due to not having libpython2.5-devel installed. This would be a requires when installing the rpm package of getvirtualbox as well as conflicting with the old virtualbox packages one might have installed.

Thanks for testing.

Installed libpython2.5-devel (2.5.2-4pclos2010)

Then run your script again and this time no error messages.

Have attached the full output in case its of any use.

Since Neal is napping I'm trying my hand at zenity.

The only issue I have now is if I press the Cancel button during the process nothing happens and it doesn't exit.

[Joble]

This was a bug reported in 2009 and according to this thread still an issue as of January:
https://bugs.launchpad.net/zenity/+bug/316904

And another one:
http://www.linuxplanet.com/linuxplanet/tutorials/6838/2/

We'll need to do a little bash programming to show off some of Zenity's more powerful capabilities. When you cascade multiple dialog boxes, you want to make it possible for a user to cancel the whole process when the "Cancel" button is clicked. This is done through the use of a special variable ($?) that Zenity sets when each dialog box exits. To check for the cancel button you must add this code after each call to Zenity:

if [ $? = 1 ];
then exit
fi

I don't know much about zenity, but I hope it helps.  (Oh darn, that's pretty geeky.)

[Neal ManBear]

Sorry, Tex. Wasn't napping. Had to wait out another storm. We've been getting some with lightening that you could see in Texas, if you happened to be looking this way when it strikes. (Okay, that's a slight exaggeration. )

The script Joble posted should do the job. Have you tried it yet?

you must add this code after each call to Zenity:

if [ $? = 1 ];
then exit
fi

I don't know where to put it.

[Neal ManBear]

At any place in the script where zenity is called, this script should be added. That would be in about 6 or 7 places, I think.

Edit: This may help explain it:

nope neither works... I dunno...   

[Neal ManBear]

Maybe:
cd /tmp
/bin/rm -f index.html inet.log
MSG=$"Testing your Internet connection..."
( wget --timeout=15 http://www.google.com/index.html -o inet.log ) 2>&1 | $ZEN2 --title="$TITLE" --progress --text "$MSG" --pulsate --auto-close | if [ $? = 1 ];

I have this odd feeling the blind is leading the blind here. 

[gseaman]

Most scripts have to end with a new empty line. This may correct that error. But what do I know? (Not much  )
