How To Check Installed GTK Version on Ubuntu Using Command Line

Ubuntu 5

In this article, we are going to delve into how you can check the installed GTK version on Ubuntu using the command line. This is a vital skill for developers and system administrators alike, as it allows you to ensure compatibility and troubleshoot potential issues.

Introduction to GTK

GTK, or the GIMP Toolkit, is a multi-platform toolkit for creating graphical user interfaces (GUIs). It is one of the most popular toolkits for the X Window System, designed for use with languages such as C, Python, and others. Knowing which version of GTK you have installed is crucial for software development and system administration tasks.

Checking the GTK Version

There are several methods you can use to check the installed GTK version on Ubuntu. We will explore three of them in this article: using apt-cache policy or dpkg -l, using dpkg --get-selections, and using dpkg-query.

Using apt-cache policy or dpkg -l

The apt-cache policy command displays the installed and candidate versions for all package records that match regex patterns. On the other hand, dpkg -l provides a list of all packages installed on your system. You can use these commands to check the installed GTK versions as follows:

apt-cache policy libgtk2.0-0 libgtk-3-0 | grep Installed

or

dpkg -l libgtk2.0-0 libgtk-3-0

These commands will display the installed versions of GTK 2 and GTK 3 libraries. libgtk2.0-0 and libgtk-3-0 are the package names for GTK 2 and GTK 3, respectively.

Using dpkg --get-selections

The dpkg --get-selections command displays a list of all packages marked for installation on your system. You can use this command to get a list of installed packages related to GTK:

dpkg --get-selections | grep 'libgtk.*bin'

This command will show the installed GTK packages, including gtk2, gtk3, and gtk4. You can then pass these package names to dpkg -l to get detailed information about each version.

Using dpkg-query

The dpkg-query command is a tool to query the dpkg database. You can use this command to check the installed version of a specific GTK package:

dpkg-query -W libgtk-3-bin

This command will display the installed version of the libgtk-3-bin package.

Conclusion

Knowing how to check the installed GTK version on Ubuntu using the command line is a valuable skill for developers and system administrators. The methods outlined in this article should provide you with the necessary tools to do so. Remember, the availability of GTK 4 may vary depending on your Ubuntu version. Always ensure to check the compatibility of your system and applications with the installed GTK version.
