let's say i did sth wrong and i want to move back in time in terminal. is there a way to do that?
i want to install this:
sudo add-apt-repository ppa:tiheum/equinox
sudo apt-get update
sudo apt-get install gtk2-engines-equinox faenza-icon-theme equinox-theme
but i'm not that sure i'll like afterwards so i want to know if i'll be able to discard it in case i dont dig it enough.
