Ubuntu: Get list of installed packages?



Question:

I want to have a list of all packages that are installed on my server but the command dpkg --get-selections > ~/Package.list doesnt do anything! When i execute it there is no file called "package.list" in the root folder.

Please help me its urgent.


Solution:1

You have to run the same command (there's no need to run it as root)

dpkg --get-selections > ~/InstalledPackages.list  

Then you can

cat ~/InstalledPackages.list  

to see the content.

Now, if you are not sure how's ~ been processed, you can

cd ~  pwd  

And that's it.


Solution:2

Use dpkg-query, this command is precisely intended to what you need: request on packages dataâ€'base. A quick man dpkg-query will tell you more, however, you may try dpkg-query --list or dpkg-query -- show.


Solution:3

You said you've looked in the root folder, but with the "~" you are clearly pointing to the home folder. The root would be /Package.list, or -/Package.list. Check in the home folder.

EDIT: As I can see now, even though my answer was correct, it might have been unclear to a fresh user. I'm sorry for introducing additional confusion. @0R10N thanks for good example :)


Solution:4

If you would like to get the versions of some installed packages, you can pipe commands like this:

dpkg --get-selections | awk '/php/{print $1}' | xargs dpkg-query --show $1  

your output would look like the following:

libapache2-mod-php5     5.3.2-1ubuntu4.29  php5-cli        5.3.2-1ubuntu4.29  php5-common     5.3.2-1ubuntu4.29  php5-gd 5.3.2-1ubuntu4.29  php5-mcrypt     5.3.2-0ubuntu1  php5-mysql      5.3.2-1ubuntu4.29  php5-xsl        5.3.2-1ubuntu4.29  phpmyadmin      4:3.3.2-1ubuntu1  


Solution:5

What's with these answers lol all this question is asking is a simple dpkg output list,

 dpkg --list | less     dpkg -l | more      dpkg-query -l | tail     dpkg-query --list | head     diff <(ps aux| grep x) <(pgrep x)     apt-file list "package"  


Solution:6

try this, may work, it work for me.

dpkg -l
