Tmux Working With Split Terminal¶

Tmux Working With Split Terminal

Tmux is a terminal multiplexer for linux systems. Tmux allows multiple terminal sessions can be accessed within a single window. Tmux is used for running more than one program in the same terminal at the same time. We can also use it to detach processes/programs from their controlling terminals. Tmux allows SSH sessions to remain active without being visible.

Creating named sessions in Tmux¶

By defaut when we create session in Tmux it will name the session with a number starting from zero.
But, we can also create the session with name also. We can do it with below command.tmux new -s my_new_session

List available sessions in Tmux¶

To list available session in Tmux execute the below command in the terminal

tmux ls

Kill a session in Tmux¶

To list available session in Tmux execute the below command in the terminal

tmux kill-session -t `my_new_session

We have to give session name instead "my_new_session". If we do not give name to session then by default an integer will be given as a session name.

Customizing Tmux¶

All the configuration of tmux is loaded from file ~/.tmux.conf . We can customize it as per our requirements.
Let's do some customizations

# Improve colors
set -g default-terminal 'screen-256color'

# Set scrollback buffer to 20000
set -g history-limit 20000

# Customize the status line
set -g status-fg  green
set -g status-bg  black
