How to List Installed Packages on Linux
Originally I was going to talk about how to list installed packages on my desktop distro of choice, Arch Linux. Then I remembered that not everybody is as enlightened as I am, so I should probably cover other distributions as well ;)
And really, it's really not a distro-centric situation, it's more about which package manager you're currently running. I've broken things out by package manager and listed which Linux distributions would be applicable.
Also, obviously the following list isn't all encompassing as it only includes five package managers that I've hand selected mostly based on my own bias of which Linux distros I check out from time to time.
If you're deeply offended that I didn't include your favorite disto, comment below. Bonus points if you include how to list the installed packages!
pacman - Arch Linux, Majaro, Antergos
pacman -QAlso, generally works the same with AUR wrappers like yay (my choice these
days), pacaur, pikaur, and yaourt.
apt / dpkg - Debian, Ubuntu, MX Linux, Mint, elementary
dpkg -lyum / dnf - Fedora, CentOS, Red Hat Enterprise Linux
rpm -qazypper - openSUSE, openSUSE Tumbleweed
zypper search -ispkgtools / slackpkg - Slackware
Couldn't leave the Linux distro that I started with off of the list!
