问题
I dont know how to properly term what i want.
I want to make a program that doesnt just print and scroll but still be a linux-CLI program.
Lets say i write a program that does 3 things: 1, its tails a logfile 2, it shows the time 3, it runs a continous ping.
And say i want the time to be displayed in lower right corner, i want the logtail to scroll in the upper 5 lines of the terminal, and i want the ping to scroll (separately) in the main body of the terminal.
So what i am asking, basicly, is: can i make a cli-program behave like a GUI-program where the clock for instance just updates without printing it again, and there are 2 seperate data streams from subprocesses that scroll independantly
Did that make sense? Im pretty new to programming.

You can control the Unix terminal more fully with the curses library. The library essentially lets you build a simple terminal GUI.
If you need more, take a look at Urwid as well. Urwid offers more complex GUI widgets for the discerning terminal GUI developer. :-)
