Finding 32-bits installed libraries

[_0R10N]

Hi! A few days I installed a couple of 32 bits libraries on my 64 bits Ubuntu so I could get a 32-bits application running. The thing is it didn't work and I'd like to get rid of all 32-bits libraries I installed.

Is there a way to find which 32-bits libraries have been installed?

Thanks!

If they are un-needed packages the following should work.

sudo apt-get autoremove

If you installed with "sudo apt-get install <blabla>", remove with ... "sudo apt-get remove <blabla>".

Thanks for the replies! I know how to remove unnecessary packages. The thing is they weren't autoremoved when running this command, they where installed as dependencies of openjdk-7-jdk:i386 and some other package.

[COLOR=#000000]_0R10N; Hi !

How about this approach:

apt-cache show openjdk-7-jdk:i386

In the output is a list of dependencies
do:

dpkg -l <dependency>

to see that status,version and other info ?

just a thought

well I would think if autoremove doesn't remove the then they are still required by some other package - but how about

apt-cache depends openjdk-7-jdk:i386

or for a more general list of i386 packages

dpkg -l | awk '$2 ~ /:i386/ {print}'

Thanks to all of you! The @steeldriver and @Bashing-om suggestions work great!
