It's annoying to have a screen full of:
Portion 1 is done
Portion 2 is done
Portion 3 is done
Portion 4 is done
I'd like it if only one line is used to tell me the current done portion. Well, it turns out there is a way to do this with bash scripts.
It turns out there is "\r" which means carriage return. So if you output a carriage return WITHOUT a newline then you essentially clear that line of text.
A simple double for loop to visually see what i'm talking about:
for j in $(seq 1 10); do for i in $(seq 1 20); do printf "$i is part of $j \r" sleep .1 done done
