repair-database (My first zenity script)

[glamdring]

Thanks to: Neal for all the help and icon, Leiche for the help and the progress bar, and any one who worked on the getvirtualbox script it was very helpful.
I decided to make this script because I remember when I first used Linux I hated rebuilding the database.
The script rebuilds and cleans the repository database according to Texstars requirements: http://www.pclinuxos.com/forum/index.php/topic,80839.0.html

REQUIRES YAD Available in Synaptic
Below are all the resource to make this yourself.
repair-database (shell script) - /usr/bin
repair-database.desktop - /usr/share/applications
dbrepair.png - /usr/share/icons


yad version
Updated as of 09/05/2011, this will be the final version unless new advances are made with the cancel button. -Thank You

Thanks to: Neal for all the help and icon, blindschLeiche for the progress bar, and any one who worked on the getvirtualbox script it was very helpful.

Original post:

I finished my first zenity script and I bet I'm going to get a bunch comments on what I did wrong haha. But that is good it will help me learn.

I decided to make this script because I remember when I first used Linux I hated rebuilding the database.
The script rebuilds and cleans the repository database according to Texstars requirements: http://www.pclinuxos.com/forum/index.php/topic,80839.0.html

Hi,
found here some information about cancle button, hopeful it's what you need 

--text=STRING     Set the dialog text
--percentage=INT  Set initial percentage
--auto-close      Close dialog when 100% has been reached
--auto-kill       Kill parent process if cancel button is pressed
--pulsate         Pulsate progress bar

Good luck, and congratulations for your first script 

[Neal ManBear]

Moving this to Code Hackers.

[glamdring]

auto-kill worked perfectly!


Now to figure out how I can add this to my menu or make a icon that can launch it. Dose any one know how to make a window come up with a root login? Like when you launch synaptic.

[Neal ManBear]

You would need to create a .desktop file for it to have it show in your menu. Check /usr/share/applications for examples.

The Exec= line will be either gksu /usr/bin/app-name (if you put it in /usr/bin) or kdesu /usr/bin/app-name, if you're using kde.

[glamdring]

Okay so some good some bad.

Launching of it from terminal it works fine, but launching it by clicking on the script has some problem with closing. If i close the script at any time it just relaunches it and even if I let it work all the way through it still relaunches the script. Will this even be a problem if I made a menu entry?

I'm Using

Code: [Select]

kdesu /usr/bin/repair-database

[Neal ManBear]

Have you updated the script in your first post? If not, please do.
What settings do you have for your script?

Here is an icon. If it doesn't suit, let me know.

[glamdring]

Just updated them.

No special settings for script just 755.

[Neal ManBear]

Just updated them.

No special settings for script just 755.

Did you mark it as executable?

[Neal ManBear]

I installed to my test box, from file manager superuser mode, I right clicked, chose Open and then Open in Terminal. The feedback I'm getting in terminal is -

Code: [Select]

--auto-close is not supported for this dialog
No duplicate/multiple versions of rpms found.
The progress bar closes, and the the process begins again. Same output repeated over and over.

[glamdring]

Sorry gave you the wrong update I had to remove --auto-close in the question ill update now.

EDIT
But still getting the same thing if not launched from terminal. (Yes executable is marked)

[Neal ManBear]

Some other scripts you may want to have a look at are --
getopenoffice
addlocale
dupeclean-gui
lx-autostart
ezswitch

(for starters )

I believe you will learn something useful from each of them.

Thanks a lot already learning a lot from getopenooffice. Working on the script hope to post a newer version later today!

[glamdring]

After using the whole xterm system I found in many of Pclos scripts my login works right. But it would be nice if some one could explain to me how it works. I understand everything besides the part under #setup XURD I know its exporting the file to /tmp/repair-database because I had to make it delete that file when done or canceled or the script won't run right again.

But the cancel button on #rebuilding rpm database doesn't seem to work right. I don't see anything different from that one to the other ones but its the only one not working.

-Thanks for all the help so far guys

[daniel]

get your script, but not work for me, get this messages

Code: [Select]

/tmp/xsurepair-database: (Zeile) line 2: repair-database: (Kommando nicht gefunden)command not found.
What is needed?

I would like to see what is wrong with cancle button by *rebuilding rpm database...


EDIT:

okay found the mistake

Code: [Select]

XURD=/tmp/xsurepair-database
change to

Code: [Select]

XURD='/tmp/xsurepair-database'
then it will work...

Should it not call

Do you want to repair the repository database?
