tmux.conf — Tokyo Night theme, top status bar, Emacs copy mode, fzf session switcher

README.md

tmux.conf

My tmux config. Tokyo Night color scheme, top status bar with system stats, Emacs-style copy mode, and fzf session switching.

Prerequisites

• tmux 3.3+
• TPM (Tmux Plugin Manager)
• fzf (for session switcher popup)
• A Nerd Font (for status bar icons)

Install

# Install TPM
git clone https://github.com/tmux-plugins/tpm ~/.config/tmux/plugins/tpm

# Copy config and scripts
mkdir -p ~/.config/tmux
cp tmux.conf ~/.config/tmux/tmux.conf
cp *.sh ~/.config/tmux/
chmod +x ~/.config/tmux/*.sh

# Start tmux and install plugins
tmux
# Press C-s I (capital I) to install plugins via TPM

Features

• Tokyo Night color scheme with rounded pill-shaped status tabs
• Rainbow window tabs — each window index gets a unique color
• Top status bar with CPU, RAM, disk usage, hostname, and clock
• fzf session/window tree (C-s s) — expand/collapse sessions, fuzzy filter, Alt+0-9/a-z jump keys
• Emacs copy mode with C-space to select, Enter to copy
• Mouse toggle (C-s M) for text selection on iPad/mobile

Helper scripts

All scripts go in ~/.config/tmux/ and need chmod +x:

Script	Purpose
session-tree.sh	fzf session/window tree picker
mouse-indicator.sh	Shows ON/OFF mouse mode in status bar
ram-usage.sh	Displays RAM usage (used/total)
disk-usage.sh	Displays disk usage for root partition
session-prev.sh	Cycle to previous session by creation order
session-next.sh	Cycle to next session by creation order
toggle-status.sh	Toggle between full and minimal status bar

The tmux-cpu plugin handles CPU percentage automatically.

Key bindings

Key	Action
C-s	Prefix (replaces default C-b)
C-s C-s	Send literal C-s to terminal
C-s r	Reload config
C-s h/j/k/l	Navigate panes (vim-style)
C-s |	Split horizontally
C-s -	Split vertically
C-s n/p	Next/previous window (repeatable)
C-s (/)	Previous/next session (repeatable)
C-s s	fzf session/window tree picker
C-s S	Built-in choose-tree
C-s B	Toggle status bar
C-s M	Toggle mouse mode
C-s [	Enter copy mode (Emacs keys)

ram-usage.sh
