This Thanksgiving, I am thankful for Vim. Vim, which stands for “Vi Improved,” is a text editor that is based on Vi, an older editor that was used with the original Unix operating system. Vim is free, open source software that comes with most modern Linux distributions. It is mostly for writing programs and scripts, but can be used to edit any sort of basic text file. It is designed so that the user never has to take their hands off of the keyboard or touch a mouse. If you use Vim properly, your palms can stay in the same position while only your fingers move. For this reason, Vim users are occasionally referred to as keyboard cowboys.
