Update one Statusbar in realtime from bash?

[_-Caleb-_]

Hi,

I'm trying to recreate an old utility called status in yab, this shown a statusbar and it's updated from bash...




Before start i'm asking if it's possible with yab, and if it, how is the better way? Im thinking in a program reading a file every x seconds and change this file with the % in every pass...

But sure exists a better solution.

Thanks in advanced!
