Here's my situation: I open terminal and run program which displays live feed in terminal (text) what changes every second. Only "Enter" key can be used while this program is running (it exits that program). So you can't type anything else into console.
I would like to write that terminal contents into a file, like after every second.
How do I do it? By opening 2nd console and using some command? Can't get it work with setterm -dump command.
