If I understand you correctly, you can do this to create a screen for a command, that will terminate when the command is complete.

Code:

screen -d -m -S ScreenName1 yes

Yes is a command, you can replace it with any command you would like.

No, you understand me wrongly. By "run given program" i rather mean "start program and leave it running" and proceed after that new iteration. After whole 5 iterations i must have 5 windows within 1 screen with 5 runned programs

What do you mean, "have 5 windows"? Are you talking about doing this in the gui?

I talk about those windows that i can selec within one screen session:

Quote:

" windowlist -b
- select -
0 select 0
1 select 1
2 select 2
3 select 3
4 select 4
5 select 5
6 select 6
7 select 7
8 select 8
9 select 9

Ok.. in that case. You can start a main screen by:

Code:

screen

Once in that screen[0] type:

Code:

screen

Once in that screen[1] type:

Code:

Crtl-A A

Now you are back in the original screen[0], type:

Code:

screen

Now you are in screen[2], type:

Code:

Ctrl-A A

Now you are back in the original screen[0], type:

Code:

screen

and so on. From screen[0] you can do a

Ctrl-a :
windowlist

to select.

Also, you should add this to your .screenrc file to make it easier to understand where you are:

Code:

caption always "%{= kw}%-w%{= BW}%n %t%{-}%+w %-= @%H - %LD %d %LM - %c"

And again. Main point to do all that stuff via script, not typing C-A and other nonprintable ones... Is it possible at all? Besides you rather use nested screens. It's possible to do without nesting.

In this case i mean just simpler combination C-A + c. Maybe, it's same. Anyway. I did it rather manually but question with script still in power. About to think that it's impossible...

Yeah, very important thing!
