neercs is a work-in-progress libcaca project.

Like GNU screen, it allows you to detach a session from a terminal, but provides unique features:

* Grabbing a process that you forgot to start inside neercs
* Great screensaver
* 3D rotating cube to switch between full screen terms
* Real time thumbnails of your shells
* Special effects when closing a window
* Various window layouts...

neercs was written by Sam Hocevar, Jean-Yves Lamoureux and Pascal Terjan. It is free software, and can be used, modified and distributed under the terms of the Do What The Fuck You Want To Public License.

The GNU Project has provided dozens of useful utilities that you can find on almost every major Linux system, but many new Linux users have no idea where to start to learn these handy utilities. In this tutorial, I'll cover a few of the utilities that you can use to measure file system usage, verify the size of files, and take a peek into larger text files like Apache logs.
