Overview of this book

Websites, online services, databases, and pretty much every other computer that offers public services runs on Linux. From small servers to clusters, Linux is anywhere and everywhere. With such a broad usage, the demand for Linux specialists is ever growing. For the engineers out there, this means being able to develop, interconnect, and maintain Linux environments. This book will help you increase your terminal productivity by using Terminator, Guake and other tools. It will start by installing Ubuntu and will explore tools and techniques that will help you to achieve more work with less effort. Next, it will then focus on Terminator, the ultimate terminal, and vim, one of the most intelligent console editors. Futhermore, the readers will see how they can increase their command line productivity by using sed, find, tmux, network, autoenv. The readers will also see how they can edit files without leaving the terminal and use the screen space efficiently and copy-paste like a pro. Towards the end, we focus on network settings, Git hacks, and creating portable environments for development and production using Docker. Through this book, you will improve your terminal productivity by seeing how to use different tools.

Vim password manager

Vim can also be used to safely store information, by encrypting text files with different cryp methods. To see the cryp method that Vim is currently using, type:

:set cryptmethod?

We can see in our case it is zip, which is not actually a crypto method and does not offer much in terms of security. To see what different alternatives we have, we can type:

:h 'cryptmethod'

A page describing the different encryption methods comes up. We can choose from zip, blowfish, and blowfish2.The most secure and recommended one is, of course, blowfish2. To change the encryption method, type:

:set cryptmethod=blowfish2

This can be also added to vimrc so that it becomes the default encryption. Now we can safely encrypt files using Vim.

A common scenario would be storing a passwords file.

Let's open up a new file named passwords.txt, add some dummy passwords inside, and save it. The next step is to encrypt the file with a password, and for this we type :X.

Vim will prompt you for a password twice...
