| Fact | Value |
|---|---|
| Repo | git@github.com:dongzhuoyao/tao-tmux-zsh.git |
| Prefix | C-b (default) + C-a (secondary, Screen-compatible) |
| Theme | Gruvbox dark (self-contained, no TPM needed) |
| Config size | ~200 lines of pure tmux config |
| Scrollback | 50,000 lines |

# Clone
git clone git@github.com:dongzhuoyao/tao-tmux-zsh.git ~/tao-tmux-zsh
# Backup existing config
[ -f ~/.tmux.conf ] && mv ~/.tmux.conf ~/.tmux.conf.bak
# Symlink
ln -sf ~/tao-tmux-zsh/tmux.conf ~/.tmux.conf
# Reload (if tmux is already running)
tmux source-file ~/.tmux.conf
All bindings use the prefix key (C-b or C-a) unless noted.
| Binding | Action |
|---|---|
h / j / k / l | Pane navigation (vim-style) |
Tab | Switch to last active window |
C-h / C-l | Previous / next window |
| Binding | Action |
|---|---|
- | Split horizontal (retains current path) |
_ | Split vertical (retains current path) |
H / J / K / L | Resize pane |
c | New window (retains current path) |
m | Toggle mouse on/off |
r | Reload tmux config |
| Binding | Action |
|---|---|
Enter | Enter copy mode |
v | Begin selection |
C-v | Toggle rectangle selection |
y | Yank (copy) selection |
macOS clipboard integration available via prefix + y.
prefix + m — useful for scrolling and pane selection# Inside tmux: prefix + r
# Or from shell:
tmux source-file ~/.tmux.conf
cd ~/tao-tmux-zsh && git pull
tmux source-file ~/.tmux.conf
| Issue | Fix |
|---|---|
| Colors look wrong | Ensure terminal supports true color; check echo $TERM shows xterm-256color or similar |
| Clipboard not working (macOS) | Install reattach-to-user-namespace: brew install reattach-to-user-namespace |
| Tmux config not loading | Verify symlink: ls -la ~/.tmux.conf should point to ~/tao-tmux-zsh/tmux.conf |
| Anti-Pattern | What goes wrong | Fix |
|---|---|---|
| Installing TPM and adding many plugins | Slow startup, fails on remote servers without internet | This config is self-contained — no TPM needed |
Leaving TERM=xterm on a remote server | Colors mangled, key bindings break, copy-mode glitches | Set TERM=xterm-256color (in zshrc or ~/.ssh/config via SetEnv) |
Editing ~/.tmux.conf directly after symlinking | Edits get lost on next git pull of the dotfiles repo | Edit ~/tao-tmux-zsh/tmux.conf and re-source |
Patching pbcopy into Linux server config | Errors — pbcopy is macOS only | Let the config branch by OS; do not patch in pbcopy on Linux |
| Starting multiple tmux servers per user | Sessions diverge across servers; confusing reattach | Use tmux a to attach to the existing server |
| Forgetting to reload after editing config | Changes don't take effect until restart | prefix + r or tmux source-file ~/.tmux.conf |
