Apt-Get is a powerful repository management tool available in Ubuntu. It allows you to install common packages immediately, removing the need to manually compile from source.
Search Packages in Apt-Get
Searching available packages in Apt-Get is easy, simply issue the following to search all packages named ‘nmap’:
apt-cache search nmap
Additionally, you can organise your output by suffixing the following flags:
–names-only (display package names only, not names and descriptions)
–installed (display installed packages only, not installed and available)
Installing Packages using Apt-Get
Searching was easy, so is installing. Here’s an example of using Apt-Get to install nmap:
apt-get install nmap
Worried about dependencies? You can resolve them directly using the following command instead:
apt-get build-dep nmap
Removing / Uninstalling Packages in Apt-Get
Need to remove an installed package using Apt-Get? Issue the following command to remove nmap using Apt-Get:
apt-get remove nmap
If you want to remove the configuration files in addition to removing the package, you can embed the ‘purge’ flag:
apt-get remove nmap --purge
