How To Find Out Package Dependencies in Ubuntu With apt-rdepends

This tutorial will teach you how to find out or check all the dependencies of a package in Ubuntu using apt-rdepends.

apt-rdepends is the utility that performs recursive dependency listings of a Debian/Ubuntu package. This open source utility searches throught the  APT cache to find out all the package dependencies.

In Ubuntu , you can install apt-rdepends by running following commands in the terminal.

sudo apt-get install apt-rdepends

Once installed, you need to run following command to list down all the dependencies of a package using apt-rdepends.

apt-rdepends <package_name>

where,

<package_name> is the name of the package dependencies of which you are going to check.

For example,

To list down the dependencies of tar package, we need to run the following command in the terminal.

apt-rdepends tar

The output is as shown below.
