Some Screen (the application) questions.

[janosh]

In the last weeks, I've started using screen when doing large emerges like update world.
At the moment, I'm reemerging 114 packages to remove some use-flags.

To check the progress of the emerge, i find my self constantly login in to a root-shell and reopening screen.
Just to get the window-title of the terminal to tell me how many packages it have emerged, and how many to go.
Then I log out.

I'm wondering if there is some way to just get the current window title out of the screen session, and display it somewhere.
Ideally I should be able to do this as a regular user i.e. not root.

The coolest thing would be if I was able to run a small application in the task-bar that on mouse over would pop-up the current screen-session window-title.

Any ideas?

Hmmm, I'm not sure how much this helps, but I'll give you what I have

(1) If you run screen as root your regular user probably won't be able to see anything from the screens.
(2) If the progress is less relevant that when it finishes, you could make a php-script to mail yourself when emerge is done. That should be VERY basic, and I could help you write it myself.
(3) If you make some sort of script (php/bash/whatever) then you could run the script as root and feed info to your user.
This is however limited by the fact that "screen -list" doesn't show the title of the screens. Perhaps that can be overcome.
If a script could extract the title, the script could create a file on your desktop and update the name of the relevant info.
(4) An application with on mouse over effect I have no idea how to create, so your on your own there ^^

My 2 cents

Everything helps ,
I know that you can set up screen so other people can have read-only access to it, so I think I should be able to log in to the root screen as a user.

Also, it's the progress I'm interested in. Especially the window title, because it tells me if something has gone wrong.

I guess my original question runs down to this:
How do you get the window title out of a screen session?

Anyone else done something like this?

I found a solution:
I just have screen log its output to a file, and then i can cat the logfile as a regular user.

[ok]

To check the progress of emerge you can use the logfile: /var/log/emerge.log
grep '>>> emerge' /var/log/emerge.log | sed 'H;/(1 of/h;$!d;g' | cut -d " " -f 5-8
if you emerge genlop you can use the following script:
