Under Ubuntu 14.04, I'm writing a script that output a lot of text (several commands...), and I would like to keep one or more lines always on top of the terminal screen to display what's running title. In other words, I try to reduce terminal vertical scroll zone and write in that non-scrolling zone.
How can I do that? I saw similar stuff using a loop catching output line by line, but I'm unable to find a way to tell the system to print from let's say line 2 or 3.
Thanks for your answers,
Nicolas
