If you've been working with Windows all your life, the concept of dependencies in Linux might initially seem confusing. In this article, we will take a detailed look at this topic and explain how dependencies affect package management.
Dependencies in Linux are additional software components required for an application to install and run. Simply put, they are what a program needs to function properly. This is because Linux developers typically write programs in a modular way.
Imagine you want to assemble furniture for your living room, but you need to buy additional tools. In this case, the furniture is the program, and the screwdriver, hammer, and screws are the dependencies.
In Linux, a dependency is an external library or program that must be installed for another program to work correctly. For example, if you install a video player, it might require a library for handling video formats. Without this library, the program won't be able to play videos properly.
Let’s say you want to install an image editing program (like GIMP), and it may require a library to handle color processing. Without this library, the application won’t display colors correctly.
Linux has package managers (like APT in Ubuntu or pacman in Arch) that automatically install all the necessary dependencies for a program to work correctly.
Linux distribution package websites usually list the dependencies of packages in their descriptions. If the information is not there, you can check it yourself.
In Debian or Ubuntu, you can use the command:
apt show [package_name]
For Arch users, the command is:
pacman -Si [package_name]
In Fedora, the package manager is DNF. To check dependencies, run the following command in the terminal:
dnf deplist [package_name]
Dependencies in Linux are like invisible helpers without which programs cannot function. Understanding their importance opens up new opportunities for efficient software management and makes interacting with the system more predictable.
