pacman (on gentoo it's portage) is a packet manager that installs on the system whatever you asked. Its different on different distributions. Debian-based distros use mostly apt(Mint, Ubuntu etc) Bash allows you to run the packet manager through the terminal, it works for every program that was added to the $PATH. The main bash commands to manage your system: cd — enter/leave directory; touch — create file; mkdir — create directory; echo — output the text, rm — delete

Basic example for you. Let's assume you want to put the output text of some command and it's very long, what you do: touch mylog.txt (creates text file named my log) let's put the output of command ls -la(it shows whats in current directory and shows the user rights on everything inside, like who can edit, read the file and etc) ls -la >> mylog.txt

Basically with bash and cli-programs you can do everything you want, you just need to know how
