tmux Session Control

Control tmux sessions by sending keystrokes and reading output. Essential for managing Claude Code sessions.

When to Use

✅ USE this skill when:

  • Monitoring Claude/Codex sessions in tmux
  • Sending input to interactive terminal applications
  • Scraping output from long-running processes in tmux
  • Navigating tmux panes/windows programmatically
  • Checking on background work in existing sessions

When NOT to Use

❌ DON'T use this skill when:

  • Running one-off shell commands → use exec tool directly
  • Starting new background processes → use exec with background:true
  • Non-interactive scripts → use exec tool
  • The process isn't in tmux
  • You need to create a new tmux session → use exec with tmux new-session

Example Sessions

SessionPurpose
sharedPrimary interactive session
worker-2 - worker-8Parallel worker sessions

Common Commands

List Sessions
bash
tmux list-sessions
tmux ls
Capture Output
bash
# Last 20 lines of pane
tmux capture-pane -t shared -p | tail -20
 
# Entire scrollback
tmux capture-pane -t shared -p -S -
 
# Specific pane in window
tmux capture-pane -t shared:0.0 -p
Send Keys
bash
# Send text (doesn't press Enter)
tmux send-keys -t shared "hello"
 
# Send text + Enter
tmux send-keys -t shared "y" Enter
 
# Send special keys
tmux send-keys -t shared Enter
tmux send-keys -t shared Escape
tmux send-keys -t shared C-c          # Ctrl+C
tmux send-keys -t shared C-d          # Ctrl+D (EOF)
tmux send-keys -t shared C-z          # Ctrl+Z (suspend)
Window/Pane Navigation
bash
# Select window
tmux select-window -t shared:0
 
# Select pane
tmux select-pane -t shared:0.1
 
# List windows
tmux list-windows -t shared
Session Management
bash
# Create new session
tmux new-session -d -s newsession
 
# Kill session
tmux kill-session -t sessionname
 
# Rename session
tmux rename-session -t old new

Sending Input Safely

For interactive TUIs (Claude Code, Codex, etc.), split text and Enter into separate sends to avoid paste/multiline edge cases:

bash
tmux send-keys -t shared -l -- "Please apply the patch in src/foo.ts"
sleep 0.1
tmux send-keys -t shared Enter

Claude Code Session Patterns

Check if Session Needs Input
bash
# Look for prompts
tmux capture-pane -t worker-3 -p | tail -10 | grep -E "❯|Yes.*No|proceed|permission"
Approve Claude Code Prompt
bash
# Send 'y' and Enter
tmux send-keys -t worker-3 'y' Enter
 
# Or select numbered option
tmux send-keys -t worker-3 '2' Enter
Check All Sessions Status
bash
for s in shared worker-2 worker-3 worker-4 worker-5 worker-6 worker-7 worker-8; do
  echo "=== $s ==="
  tmux capture-pane -t $s -p 2>/dev/null | tail -5
done
Send Task to Session
bash
tmux send-keys -t worker-4 "Fix the bug in auth.js" Enter

Notes

  • Use capture-pane -p to print to stdout (essential for scripting)
  • -S - captures entire scrollback history
  • Target format: session:window.pane (e.g., shared:0.0)
  • Sessions persist across SSH disconnects
