“ sudo apt-get-update-plus ” is the same as “ sudo apt-get update && sudo apt-get ”

sudo apt-get-update-plus basically just removes the additional && sudo apt-get meaning you can use apt-get update with an additional command afterwards.

So instead of:

sudo apt-get update && sudo apt-get dist-upgrade

you can use:

sudo apt-get-update-plus dist-upgrade

you can use any of the additional commands for example:

sudo apt-get-update-plus install

sudo apt-get-update-plus clean

sudo apt-get-update-plus autoremove

I think it would be less complicated if “plus” was replaced with “and” instead.
