If you are using a Debian-based Linux system, command the software effectively. Whether you are installing new applications, searching for updates, or looking for available packages, apt search is a vital command. The APT (Advanced Package Tool) package manager gives users the ability to search through repositories, search for information about certain packages, and even see what’s already installed. But how do you search apt, find certain software, or check if a package is installed?
So, in this guide, we’re going to detail how to search installed apt packages, how apt search package commands work, and how you can make sure you can quickly retrieve software information from any Debian-based system. Learning to search apt is crucial for anybody from novice to advanced Linux users; it improves the workflow and is a positive step towards other package management.
Why Use apt search?
This command is used to search for software packages in Debian repositories. This is especially helpful when:
- You want to add a package, but you aren’t sure of its precise name
- You should check whether a package is available in the repository.
- You want to check whether you already have a package installed in your system.
- You are looking for related packages that have a copy of the same use case.
While dpkg only checks installed packages, this command searches both currently installed and other software available in the repository.

Searching for installed APT packages
All apt packages installed, search only:
Those that were installed with apt can be found with:
Example:
RUN apt list --installed | grep nginx
This will filter out just the installed packages related to “nginx.”
Alternatively, you can use:
dpkg -l | grep package-name
Example:
dpkg -l | grep mysql
This will list a more specific list of installed packages based on the search criteria.
Searching APT and Finding Available Versions
To see all available versions of a package in the repo:

apt-cache policy package-name
Example:
apt-cache madison php
This displays the available PHP versions in the APT repository.
Another way to check apt for available versions is:
apt list -a package-name
Example:
apt list -a git
This will provide you with a list of everything available for Git in your repos.
Searching for Packages by Description
You might not remember the exact name of the package but remember what it does. In such cases, use:
apt search keyword
Example:
apt search firewall
It will produce a list of packages for firewall management, and you can pick the one you want.
Check For Packages Needing An Upgrade
To see all available packages that can be upgraded, run:
apt list --upgradable
This command returns a list of installed packages with newer versions in the repository.
