Tmux (Terminal Multiplexer) is a powerful tool for managing multiple terminal sessions. However, resizing and navigating panes can be tricky. Here’s how to streamline your workflow.
Basic Tmux Commands
- Start a new session:
tmux new -s mysession
- Split panes horizontally:
Ctrl+b %
- Split panes vertically:
Ctrl+b "
- Navigate between panes:
Ctrl+b Arrow Keys
Resizing Panes Like a Pro
- Resize pane left:
Ctrl+b :resize-pane -L 5
- Resize pane right:
Ctrl+b :resize-pane -R 5
- Resize pane up/down:
Ctrl+b :resize-pane -U 5 Ctrl+b :resize-pane -D 5
You Should Know:
1. Mouse Support – Enable it in `~/.tmux.conf`:
set -g mouse on
2. Scroll in Tmux – Use `Ctrl+b [` to enter scroll mode, then navigate with arrow keys.
3. Zoom a Pane – Temporarily maximize a pane with Ctrl+b z.
4. Session Management – Detach with Ctrl+b d, reattach with:
tmux attach -t mysession
5. Quick Pane Swapping – Move a pane with `Ctrl+b {` (left) or `Ctrl+b }` (right).
Advanced Customization
Add these to `~/.tmux.conf` for better efficiency:
Vim-like pane navigation bind h select-pane -L bind j select-pane -D bind k select-pane -U bind l select-pane -R Faster pane resizing bind -r H resize-pane -L 5 bind -r J resize-pane -D 5 bind -r K resize-pane -U 5 bind -r L resize-pane -R 5
What Undercode Say
Tmux is essential for power users, but mastering pane navigation and resizing is key. Use mouse mode for beginners, but keyboard shortcuts for speed. Customize `.tmux.conf` to fit your workflow, and practice commands like `resize-pane` and `select-pane` until they’re second nature.
Expected Output:
A streamlined Tmux workflow with faster pane management, improved navigation, and custom key bindings for efficiency.
Prediction
As terminal-based workflows grow, Tmux will remain a staple for developers and sysadmins, with more plugins enhancing pane management and session persistence.
