# pacman
**pacman** is Arch Linux's default package manager.


# Common operations
Upgrade the system with ``pacman -Syu``
Remove a package along with unneeded dependencies with ``pacman -Rsn notepad.`` Note that this sometimes breaks packages or fails to remove because of intertwining dependencies.

Delete the entire package cache with ``pacman -Scc``. Note that you will not be able to reinstall or downgrade to older packages without a network connection because of this. 


## Cleanup
Remove unneeded packages with `pacman -Qdtq | pacman -Rns -`
Keep a package by marking it as explicitly installed with `pacman -D --asexplicit package`

Remove more packages with `pacman -Qqd | pacman -Rsu --print -`

Get list of third-party (AUR) packages with ``pacman -Qqm``
