I am running 16 debug processes simultaneously with our adapted gdb (called e-gdb). The processes are invoked by a bash script, using:

gnome-terminal -e 'e-gdb -x gdbNN.cmd progNN.e'

To manage the multiple sessions I can open multiple terminals using the --geometry option to arrange them tiled on my screen. Alternatively, I can use the --tab option to have them all in one terminal.

When the sessions end I close the terminal(s) with a click (I don't want it to auto-close).

So, with multiple terms I need to click 16 times while with tabs I click once, but I have to switch between tabs to see the session results. I would like tiled tabs in a terminal so I can view them simultaneously and close all in a single click.

Is there a way to tile tabs?
If not, can I close all debug terminals in one action?

UPDATE: Is there an easy way to kill multiple terminals based on their title? I am using the -t option to name the windows. Is there something like kill -name '*DBG*'?
