I have been using sublime text (ST) at work for quite a while now and I really love stuff like multi-cursor editing or the mini-map navigation. Being a GUI software, ST is intended for use on a local workstation. Since I had (and still have) no idea if you can somehow edit remote files with ST, I decided to give vim a shot.
To quote Wikipedia:
Vim is a clone of Bill Joy's vi editor for Unix. It was written by Bram Moolenaar based on source for a port of the Stevie editor to the Amiga and first released publicly in 1991. Vim is designed for use both from a command-line interface and as a standalone application in a graphical user interface. Vim is free and open source software and is released under a license that includes some charityware clauses, encouraging users who enjoy the software to consider donating to children in Uganda. The license is compatible with the GNU General Public License.
Tmux is a terminal multiplexer, and its purpose is to enable you to use any number of terminals within a terminal. If you know screen you get the general idea, otherwise take a look at the screenshot below:
A practical application for web development with tmux would be having three terminal sessions in a grid layout like the one above. The left most sessions containing your code editor (i.e. vim), the session in the upper right containing the output of some monitoring process like browser-sync or grunt, and finally the session in the lower right for committing and pushing any changes made to your code.
Have you ever played Quake or a similar 1st person shooter where you could access a console for entering commands by pressing the ~ key? Well, tilda does that for your Linux desktop! Press ~ and a drop-down console will appear from the top of your screen. Enter commands, execute scripts or start programs just like you would do with any command line interface. Press ~ again and make your drop-down console disappear again!
