If you run a live or home server, moving files between local machines or two remote machines is a basic requirement. There are many ways to achieve that. In this article, we talk about scp (secure copy command) that encrypts the transferred file and password so no one can snoop. With scp you don’t have to start an FTP session or log into the system.

When using GUI-based text/source code editors, some features are a given, such as selecting text. I mean, most of us won't even consider this a feature anymore. But that's not the case with command line based editors like Vim. Specifically for Vim, when only using keyboard, you'll have to learn certain commands in order to select text the way you want. In this tutorial we will discuss this feature as well as the 'marks' feature of Vim in detail.
