+title: Pacman Cheat Sheet For Ubuntu Users
+date: 2020-08-24
+description: My Pacman cheat sheet for Ubuntu Users.
+tags: [Arch]
+---
+
+As a regular Ubuntu user I am used to using *apt* for system maintenance. But now that I've installed [Arch Linux](/posts/installing-arch-linux-on-a-x220-thinkpad/) I will be using *pacman* and so below is a cheat sheet for myself that shows the *pacman* equivalent of some common *apt* actions.
+
+
+Action | Apt | Pacman |
+-------|-----|--------------------|
+Install a package  | apt install <package name>| pacman -S <package name> |
+Remove a package  | apt remove <package name> | pacman -Rs <package name> |
+Search for a package | apt serch <search term> | pacman -Ss <regexp> |
+Upgrade packages | apt update && apt upgrade | pacman -Syu |
+Upgrade distribution | apt update && apt dist-upgrade | pacman -Syu |
+Clean up local caches | apt autoclean | pacman -Scc |
+Remove unused dependencies | apt autoremove | pacman -Qmq | pacman -Rs - |
+
+
+## Install a Package
+
+```shell
+$ pacman --sync <package name>
+
+$ pacman -S <package name>
+```
+
+Installs a package and its dependencies.
+
+## Remove a Package
+
+```shell
+$ pacman --remove --recursive <package name>
+
+$ pacman -Rs <package name>
+```
+
+Removes a package and all its dependencies, provided that (A) they are not required by other packages; and (B) they were not explicitly installed by the user.
+
+## Search For a Package
+
+```shell
+$ pacman --sync --search <regexp>
+
+$ pacman -Ss <regexp>
+```
+
+Searches in the sync database for packages with a name or description that match the regexp.
+
+## Upgrade Packages
+
+```shell
+$ pacman --sync --refresh --sysupgrade
+
+$ pacman -Syu
+```
+
+Downloads a fresh copy of the master package database and then upgrades all out-of-date packages.
+
+## Upgrade Distribution
+
+```shell
+$ pacman --sync --refresh --sysupgrade
+
+$ pacman -Syu
+```
+
+Since Arch uses a rolling release system there is no distribution version as you just upgrade your packages to their latest versions.
+
+## Clean Up Local Caches
+
+```shell
+$ pacman --sync --clean --clean
+
+$ pacman -Scc
+```
+
+Free up disk space by removing from the cache any packages that are no longer installed. Also removes any cached sync databases.
+
+## Remove Used Dependencies
+
+```shell
+$ pacman --query --deps --unrequired --quiet | pacman --remove --recursive -
+
+$ pacman -Qdtq | pacman -Rs -
+```
+
+Remove dependencies that are no longer needed, because e.g. the package which needed the dependencies was removed.
