I happened many times to find archives of beautiful icons. Unfortunately, these files were compressed into files with a. Icns.
This extension is used in MacOS systems to identify a file icon system [at least from what I could have understood].
But the thumbnail icons seem really wonderful ... how can I do to get into. Png?

In Ubuntu 8.04 there is no tool for conversion, but will be available on Ubuntu 8.10.
The package in question is called icnsutils, and will be available in the universe repository.
Fortunately does not require many dependencies, and you can also install it on Ubuntu Hardy.
So get the packages needed to software:
icnsutils
libicns

Saving the file to your desktop, then we terminal:

cd ~/Desktop
sudo dpkg -i libicns1_0.5.8-1_i386.deb
sudo dpkg -i icnsutils_0.5.8-1_i386.deb

Once installed packages, we can immediately start using the software for conversion.
Suppose you have a file called folders.icns on the Desktop. To extract. Png from, let's terminal:

cd ~/Desktop
icns2png -x folders.icns

After extraction, we have files on the desktop. Png of the file.
Where, then, we wanted to extract multiple archives, just point to the folder with the files. Icns with terminal and give the command:

icns2png -x *.icns
