Terminal Management with tmux

• Persistent session management (creates session named main and/or attach to it if already running)

tmux new-session -n main
# attach to main session
tmux attach -t main

• Shortcuts
  Ctrl + B -> arrow left right -> resize current view
  Ctrl + B -> % -> divide view horizontally
  Ctrl + B -> " -> divide vertically
  Ctrl + B -> ; -> go to next window

set -g default-terminal "screen-256color"

# remap prefix from 'C-b' to 'C-a'
unbind C-b
set-option -g prefix C-a
bind-key C-a send-prefix

# Resize the current pane using Alt + direction
bind -n M-k resize-pane -U 3
bind -n M-j resize-pane -D 3
