I love working with the command line. Seriously, I think there’s hardly any more productive and more versatile tool for a software developer than the terminal. Maybe it’s the hacker/wizard/neckbeard kind of feeling I get when using a terminal, I don’t know.

At work we do lots of pair programming. Everyone’s got their own laptop and can set it up the way they like. And since I love working with the command line I’ve spent quite some time doing (only sane! I swear!) modifications to my terminal environment that make working with the command line more pleasant and streamlined. This is why my pair usually will be greeted by something like this:

Spoiler! :

What's tmux?
tmux’s authors describe it as a terminal multiplexer. Behind this fancy term hides a simple concept: Within one terminal window you can open multiple windows and split-views (called “panes” in tmux lingo). Each pane will contain its own, independently running terminal instance. This allows you to have multiple terminal commands and applications running visually next to each other without the need to open multiple terminal emulator windows.
On top of that tmux keeps these windows and panes in a session. You can exit a session at any point. This is called “detaching”. tmux will keep this session alive until you kill the tmux server (e.g. when you reboot)2. This is incredibly useful because at any later point in time you can pick that session up exactly from where you left it by simply “attaching” to that session.
If you’ve ever worked with remote servers or a Raspberry Pi over ssh you can guess where this will be useful: When you lose your ssh connection the tmux session will simply be detached but will keep running on the server in the background including all the processes that run within your session. To continue your session simply ssh to the server again and attach to the running session.
But tmux is not only helpful when working on a remote machine. Not only for its window management features but also for the session handling. Personally I find myself detaching from sessions when I’m switching context. I’ll just start a new session for my new task and attach to the old session whenever I want to continue with my old task.
You see that tmux basically offers two big features: Window management in your terminal and session management. If you are familiar with GNU Screen this is nothing new. Think of tmux as an easier-to-use and a little more powerful alternative to Screen (obviously I’m being opinionated here).
Enough with the talking already. Let’s get our hands ready in the hands-on guide!

Installation:
We are going to install tmux on our machine, i'm running on Debian based distro:

sudo apt-get install tmux

Tmux Config: Tmux Config Link ( save as to /home/USERNAME/.tmux.conf or /root/.tmux.conf )

kalau saya prefer pakai terminator, walaupun fungsinya sama cuma buat split window nya , but it's usefull thread, keep share
