Doing some poking about using the suggestions of oneperson who responded before, I used:

c-a:exec myscript

        It does exactly what I  wanted.

Not necessarily for your situation, but in many circumstances screen's ability to manage multiple windows within a screen session is invaluable.
  • `^Ac` to open a new window, with a shell running in it. You could apply the editing script and edit the text file by hand, if it needs additional touch-up.
  • `^Ap` to go to the previous window - e.g. the window where lynx is running, if you just opened the new shell window. This leaves the new window around, to return using `^Ap` again, or
  • `^An` to go to the next window. You can have as many windows as you want, and navigate forward and backwards between them.
There are other ways to navigate, of course, this is just some basics.


Thanks very much.

I thank both people who responded.  As I mentioned I'm new to screen so most of what was suggested went over my head.  I will be experimennting with the responses if for no other reason then to learn more about screen.

Perhaps if I described what I want it will help.

While within lynx the browser i do a screen command "c-a h" to capture the text of the current screen to a text file.  Using "^z" to suspend lynx I drop to the command line.  With a shell script some text within the file is manipulated.  A "fg" takes me back to lynx.

Reading the man page it appeared some screen functions might permit skipping the suspend part of the above.  It would, using a screen function, send a command to the script while remaining in lynx.

I hope this is helpful, has anyone any suggestions or is it not something possible using screen?

Thanks again.
