tmux (session tool)

Introduction

The tool can help to reattach the losing sessions. It is really useful if your network connection is unstable. You can attach the losing session and keep working. In addition, it enables users to control window panes through keyboard.

Installation (Linux):

sudo apt-get update

sudo apt-get install tmux

tmux -V

In:

tmux new (it will use number to name the session)

tmux new -s name-of-session

Out:

How to customize it?

The keyboard combination of prefix seems to be not that user friendly. If we can change it to something else, that will be really appreciated.

First, we need to create a tmux configuration file.

    vim ~/.tmux.conf

Copy the following instructions into that file.

    unbind c-b

    set -g prefix C-a

    bind C-a send-prefix

The above instructions mean that we change prefix from ctrl + b to ctrl + a.
