dpkg is also a good option, especially if you don’t know the exact package name

:~$ dpkg -l
or in combination with grep
:~$ dpkg -l | grep ruby
or if you expecting a lot of matches
:~$ dpkg -l | grep lib | less

you can also use regular expression patterns with grep

that’s better. Here’s what the output looks like

amir@amir-desktop:~$ apt-show-versions -a ruby
ruby 1.8.2-1 install ok installed
No stable version
ruby 1.8.2-1 dapper
ruby/dapper uptodate 1.8.2-1

The previous comment was supposed to show the example as:

apt-show-versions -a

I hope that works better!! Wot no preview?!

apt-show-versions is a gem of a tool
(you need to sudo apt-get install apt-show-versions)

apt-show-versions -a

lists all available versions on the apt repository servers (aswell as the installed version, if there is one)

This is occasionally very useful
