Pacman

When I migrated from Ubuntu to Arch I had a hard time remembering Pacman's (the Arch package manager) commands. Here we go:

• pacman -Sy updates the package lists
• pacman -Su upgrades the system
• pacman -Syu updates and upgrades
• pacman -Ss searches for installable packages
• pacman -R removes a package
• pacman -Rs removes a package and its dependencies
• pacman -Qi shows info about an installed package
• pacman -Ql list all files of an installed package
• pacman -Qm show all installed AUR packages
• pacman -Qo /path/to/filename shows which package a file belongs to
• pacman -Qe lists all packages explicitly installed
• pacman -Qd lists all packages installed as a dependency for another package
• pacman -Qt searches for missed installed orphans / packages that not required by any other packages
• pacman -Fs searches for a file in installable packages
• pacman -Sc clears uninstalled packages from cache
• pacman -Scc clears all cached packages
• pacman -U file:///var/cache/pacman/pkg/package.zst downgrades a package from cache

Consider using yay as a frontend for pacman. Really convernient + fast. Plus you can manage AUR packages with it as well.

Update 2019: Nah.

I use the following aliases/bash functions in .bashrc:

alias upd='sudo pacman -Syu'

alias ins='sudo pacman -Sy'

alias aursearch='curl -s https://aur.archlinux.org/packages.gz
| zgrep'

aurinst () { pushd /home/psic4t/sys/aur &&
git clone https://aur.archlinux.org/"$1".git &&
cd "$1" && makepkg -si && popd; }
