How to find a package version in Linux
Have you ever wondered how to find the version of an installed package in Linux? Of course, you are. Nowadays, Package management is much more better than before, with the help of many graphical package managers. However, I always prefer the command line to get things done faster and easier. There are different commands available to find out the package version in different flavours of Linux. Today, in this tutorial, we will be seeing how to find a package version in some popular Linux distributions such as Arch Linux and its derivatives, Debian and its derivatives, RHEL and its derivatives.
Find a package version in ARCH based systems
To find out an installed package(Eg. VLC) version in Arch Linux and its derivatives such as Antergos, Manjaro, run the following command:
pacman -Q vlc
As you see in the above output, the installed version of VLC package is 2.2.4-3.
To display the extensive details of a package, run:
pacman -Qi vlc

Find a package version in DEB based systems
In Debian, Ubuntu and its derivatives such as Linux Mint, Elementary OS, we can find the installed package(Apache webserver) version using command:
dpkg -s apache2 | grep -i version
To display the extensive information of an installed package, run:
dpkg -s apache2

Homepage: http://httpd.apache.org/ Original-Maintainer: Debian Apache Maintainers <firstname.lastname@example.org>
Also, we can find a package version using command:
apache2:amd64/xenial-security 2.4.18-2ubuntu3.1 uptodate apache2:i386 not installed
As you see in the above result, I have installed apache2 64 bit version, and its version is 2.4.18.
If ‘apt-show-versions’ program is not installed, you can install it using command:
sudo apt install apt-show-versions
We know now how to check the installed package’s version. What about the version of a package in the repositories? Is there anyway to check the version of packages that are available in the official repositories? It’s also possible. Check the following link to find out how.
Find a package version in RPM based systems
To find out the version of an installed package (Eg.httpd) in RPM based distributins such Red Hat, CentOS, Fedora, Scientific Linux, and openSUSE etc., run:
rpm -qi httpd
