Perhaps, but my scripts got rather convoluted along the way.

I too have to go window by window, executing the commands.  I don't like the 
idea of commands being executed in parallel in several screen windows without 
me seeing what's going on.

If you want to try and save the history and scrollback, you can take a look 
into the bashrc and save_screenrc script inside one of the windows of 
SESSION_demo in the archive.

That particular sequence of commands pretty much store/restore the history and 
scrollback to perfection.  Its one of the nicer features I like about my 
scripts.  It's like I never closed the bash window at all. =)

I too though of parsing the window list. But since window titles can contain 
spaces, it makes it kinda hard to parse it correctly.  Perhaps with some 
regex magic.

The real issue is capturing the window list.  There was a question about this 
before:
