Quick howto: List all installed packages in Linux
In today’s quick ‘just the examples’ howto, we show you how to find out what packages are installed on your Linux system with one simple command. Depending upon what distribution of Linux you have, you will use a specific packaging type and/or tool. Here’s a list of the tools you can use and which distribution(s) they are available in:
-
RPM Packages are provided on Red Hat based systems, including OpenSuSE Red Hat Linux, CentOS and Fedora: yum, RPM.
- Fedora: dnf, RPM.
- SuSE: Although SuSE does use RPM, it also uses its own package tool called zypper
- Arch: pacman
- Debian / Ubuntu and derivatives: dpkg, APT
Here are the examples you need:

RedHat / CentOS:

Debian / Ubuntu via DPKG:
Debian / Ubuntu via APT:
$ rpm -qa --lastRedHat / CentOS:
$ dnf list installedOpenSuSE:
$ zypper se --installed-onlyArch:
$ pacman -QDebian / Ubuntu via DPKG:
$ dpkg -lDebian / Ubuntu via APT:
$ apt list --installed
Don’t forget, you can redirect the output of any of these commands to a text file, for later perusal. To do that, simply type the command, followed by > filename.txt, eg: apt list –installed > packagelist.txt
