The best way to learn.

 

Website: Learn Linux The Hard Way

 

This is a simple guide written in “Learn X the hard way” style, author of which is Zed A. Shaw. The purpose of it is to give you some experience in working with Unix-like system. There are many good UNIX-Like systems out there, for example FreeBSD, OpenBSD, OpenSolaris and even MAC OS X, just to name a few. When deciding which system to use in this guide I chose Linux mainly because it is most popular UNIX-like server operating system, which means what you have much bigger chance encountering it in the wild in comparison to other UNIX derivatives. And Linux-related skills are relatively easy transferable to other UNIX-likes.

 

To complete the tasks you need the following setup

 

• A computer with Internet connection.
  
• A bit of spare time.
  
• Patience.
