When I use sudo apt-get install <package-name> for installing any package, I observe the following:


Downloading some packages (78%)

This line once printed never changes its position but instead keeps on updating itself with percentage values. While other things are changing this line remains constant! How do they do it?

You probably need to look at what echo -ne '
' does.



Here is an example:



echo -ne 'Downloading 1%

'

sleep 1



echo -ne 'Downloading 100%

'

sleep 1



echo -ne '

'
