Occasionally, you may want to check the packages installed on your system. In this article, I will demonstrate how list installed packages on Fedora. Yum package manager was used on Fedora 22 and its previous version, now (Fedora 27) we have dnf tool for package management.
1) List manually (explicitly) installed packages
To list manually installed packages in your system, run the following command
dnf history userinstalled
Sample Output
Packages installed by user httpd gnome-tweak-tool nodejs npm
2) List all installed packages
On older version say Fedora 22, if you wish to know all the installed packages in your system, run the command below
rpm -qa
Sample Output
1 hwdata-0.252-8.6.el7.x86_64
2 setup-2.8.71-7.el7.noarch
3 libpipeline-1.2.3-3.el7.x86_64
4 grub2-pc-modules-2.02-0.65.el7_4.2.noarch
5 gpgme-1.3.2-5.el7.x86_64
6 glibc-common-2.17-196.el7.x86_64
7 yum-3.4.3-154.el7.noarch
8 libstdc++-4.8.5-16.el7_4.1.x86_64
9 rhn-check-2.0.2-17.el7.noarch
10 pcre-8.32-17.el7.x86_64
11 xz-libs-5.2.2-1.el7.x86_64
12 desktop-file-utils-0.23-1.el7.x86_64
13 libxml2-2.9.1-6.el7_2.3.x86_64
NOTE: If you wish to know whether a specific package is installed, use the 'grep' filter option
In this example, we'll investigate whether httpd web server is installed or not.
rpm -qa | grep httpd
Output
httpd-tools-2.4.6-67.el7_4.6.x86_64 httpd-2.4.6-67.el7_4.6.x86_64
The results above confirm the installation and presence of httpd web server.
You can also sort the packages installed according to date i.e from latest to earliest. This can be achieved by running the command below
rpm -qa --last
Sample Output

3) Using DNF - List installed packages
In the newer version say Fedora 27, you can list all the installed packages in your system using the dnf package manager.
dnf list installed
Sample output

2 GConf2.x86_64 3.2.6-11.fc21 @System
3 LibRaw.x86_64 0.16.0-4.fc21 @System

26 PackageKit-gtk3-module.x86_64 1.0.3-2.fc21NOTE: For older Fedora versions ( Version 20 and earlier ) yum package manager is used instead of dnf. Therefore, to list installed packages the command is as shown below:
yum list installed
Sample Output
mariadb.x86_64 1:5.5.56-2.el7 @rhui-REGION-rhel-server-releases mariadb-libs.x86_64 1:5.5.56-2.el7 @anaconda/7.4 mariadb-server.x86_64 1:5.5.56-2.el7 @rhui-REGION-rhel-server-releases microcode_ctl.x86_64 2:2.1-22.2.el7 @anaconda/7.4 mozjs17.x86_64 17.0.0-19.el7 @anaconda/7.4 ncurses.x86_64 5.9-14.20130511.el7_4 @anaconda/7.4 ncurses-base.noarch 5.9-14.20130511.el7_4 @anaconda/7.4 ncurses-libs.x86_64 5.9-14.20130511.el7_4 @anaconda/7.4 net-tools.x86_64 2.0-0.22.20131004git.el7 @anaconda/7.4 newt.x86_64 0.52.15-4.el7 @anaconda/7.4 newt-python.x86_64 0.52.15-4.el7 @anaconda/7.4 nspr.x86_64 4.13.1-1.0.el7_3 @anaconda/7.4 nss.x86_64 3.28.4-15.el7_4 @anaconda/7.4 nss-pem.x86_64 1.0.3-4.el7 @anaconda/7.4 nss-softokn.x86_64
4) List orphaned packages
Orphaned packages that those packages that are no longer required by the system. rpmorphan command comes in handy when you want to view those packages so that you can later uninstall them to free up disk space.
To display orphaned libraries, run
rpmorphan
Sample Output
libcanberra-gtk2 libertas-usb8388-firmware libproxy-mozjs libreoffice-emailmerge libsane-hpaio
To display orphaned packages installed in the last 2 days, run the command below
rpmorphan --all -install-time -2
To view packages installed more than 10 days ago, run
rpmorphan --all --access -time +10
Sample Output
symlinks syslinux-extlinux system-config-printer-udev tabish-eeyek-fonts tcpdump telnet thai-scalable-waree-fonts time totem-nautilus traceroute transmission-gtk tree uboot-tools unoconv usbutils vconfig vinagre vlgothic-fonts wireless-tools words wvdial
To clean up the system of these orphaned packages, use
dnf autoremove
5) Using pkcon command to search packages
pkcon short for PackageKit console is a command line tool which can be used for many purposes including installing, updating, removing and searching packages.
To search a package run
pkcon search name package-name
For example ,
pkcon search name sshd
Sample Output
Searching by name [=========================] Starting [=========================] Finished [=========================] Available apache-sshd-0.11.0-2.fc21.noarch (fedora) Apache SSHD Available apache-sshd-javadoc-0.11.0-2.fc21.noarch (fedora) API documentation for apache-sshd Available jenkins-sshd-1.6-4.fc21.noarch (fedora) Jenkins sshd module Available jenkins-sshd-javadoc-1.6-4.fc21.noarch (fedora) Javadoc for jenkins-sshd
The above shows the files making up the sshd package.
