<section><h1>Pacman Cheat Sheet For Ubuntu Users</h1><blockquote>Mon 24th August 2020 By David T. Sadler.</blockquote><p>As a regular Ubuntu user I am used to using apt for system maintenance. But now that I've installed Arch Linux I will be using pacman and so below is a cheat sheet for myself that shows the pacman equivalent of some common apt actions.</p><pre>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 - |</pre><h2>Install a Package</h2><pre><code class="shell">$ pacman --sync <package name>
$ pacman -S <package name></code></pre><p>Installs a package and its dependencies.</p><h2>Remove a Package</h2><pre><code class="shell">$ pacman --remove --recursive <package name>
$ pacman -Rs <package name></code></pre><p>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.</p><h2>Search For a Package</h2><pre><code class="shell">$ pacman --sync --search <regexp>
$ pacman -Ss <regexp></code></pre><p>Searches in the sync database for packages with a name or description that match the regexp.</p><h2>Upgrade Packages</h2><pre><code class="shell">$ pacman --sync --refresh --sysupgrade
$ pacman -Syu</code></pre><p>Downloads a fresh copy of the master package database and then upgrades all out-of-date packages.</p><h2>Upgrade Distribution</h2><pre><code class="shell">$ pacman --sync --refresh --sysupgrade
$ pacman -Syu</code></pre><p>Since Arch uses a rolling release system there is no distribution version as you just upgrade your packages to their latest versions.</p><h2>Clean Up Local Caches</h2><pre><code class="shell">$ pacman --sync --clean --clean
$ pacman -Scc</code></pre><p>Free up disk space by removing from the cache any packages that are no longer installed. Also removes any cached sync databases.</p><h2>Remove Used Dependencies</h2><pre><code class="shell">$ pacman --query --deps --unrequired --quiet | pacman --remove --recursive -
$ pacman -Qdtq | pacman -Rs -</code></pre><p>Remove dependencies that are no longer needed, because e.g. the package which needed the dependencies was removed.</p><h3>Links</h3><a href="/posts/arch/2020-05-25/installing-arch-linux-on-a-x220-thinkpad/">Installing Arch Linux on a Thinkpad X220.</a><a href="/posts/arch/">Arch - Read More Posts.</a><p>I don't have comments as I don't want to manage them.
