Today I talk about both the basics of installing packages on an ubuntu / debian system as well as some more advanced apt / dpkg commands I've picked up over the years.
Session 1:
apt --help
apt update
sudo !!
sudo apt install emacs-nox
sudo apt purge emacs-nox
sudo apt autoremove --purge
dpkg -l | wc -l
dpkg -l | less
dpkg -l | grep emacs
aptitude why emacsen-common
dpkg -L emacsen-common
dpkg -L python3-dev
which python3
dpkg -S /usr/bin/python3
dpkg -S /usr/lib/python3Session 2:
apt-get --help
apt-cache show emacsen-common
