This page is about the ways to list the installed packages in a Debian system and how to create a file with this list. This file can be uploaded to the web (i.e. from other computer with Internet connection) to download new packages.
List all packages installed
With version and architecture information, and description, in a table:
dpkg-query -l
Package names only, one per line:
dpkg --get-selections | cut -f 1
List packages using a search pattern
It is possible to add a search pattern to list packages:
dpkg-query -l 'foo*'
Show status of all packages on the system
To check the status of all packages on your system:
dpkg -l | more
This will show all packages (1 line each) that are in various stages of install (this includes packages that were removed but not purged). To show only the installed:
dpkg -l | grep '^i'
to filter through grep to get results for "i"
You can also use:
apt-cache pkgnames
You can if you are using Debian Linux use dpkg command to list installed software:
dpkg --get-selections
And store the list installed software to a file called /backup/installed-software.log
dpkg --get-selections > /backup/installed-software.log
You can also find package information in the next directories (you can use mc or other FileManager to browse them):
/var/lib/apt/lists/*
/var/lib/dpkg/available: list of available packages.
/var/lib/dpkg/status :statuses of available packages. This file contains information about whether a package is marked for removing or not, whether it is installed or not, etc. A package marked reinst-required is broken and requires reinstallation.
Restore installed software
After re-installing base system you can immediately re-install all software. You need dselect:
apt-get install dselect
Then you have to type following commands:
dpkg --get-selections > /backup/installed-software.log dpkg --set-selections < /backup/installed-software.log
Now your list is imported use apt-get, Synaptic or other PackageManagement tools. To install the package:
apt-get dselect-upgrade
All this with a single command:
aptitude install $(cat /backup/installed-software.log | awk '{print $1}')
