tmux

```bash

SOCKET_DIR="${OPENCLAW_TMUX_SOCKET_DIR:-${CLAWDBOT_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/openclaw-tmux-sockets}}"

mkdir -p "$SOCKET_DIR"

SOCKET="$SOCKET_DIR/openclaw.sock"

SESSION=openclaw-python

tmux -S "$SOCKET" new -d -s "$SESSION" -n shell

tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- 'PYTHON_BASIC_REPL=1 python3 -q' Enter

tmux -S "$SOCKET" capture-pane -p -J -t "$SESSION":0.0 -S -200

```

After starting a session, always print monitor commands:

```

To monitor:

tmux -S "$SOCKET" attach -t "$SESSION"

tmux -S "$SOCKET" capture-pane -p -J -t "$SESSION":0.0 -S -200

```

• Use OPENCLAW_TMUX_SOCKET_DIR (legacy CLAWDBOT_TMUX_SOCKET_DIR also supported).
• Default socket path: "$OPENCLAW_TMUX_SOCKET_DIR/openclaw.sock".

• Target format: session:window.pane (defaults to :0.0).
• Keep names short; avoid spaces.
• Inspect: tmux -S "$SOCKET" list-sessions, tmux -S "$SOCKET" list-panes -a.

• List sessions on your socket: {baseDir}/scripts/find-sessions.sh -S "$SOCKET".
• Scan all sockets: {baseDir}/scripts/find-sessions.sh --all (uses OPENCLAW_TMUX_SOCKET_DIR).

• Prefer literal sends: tmux -S "$SOCKET" send-keys -t target -l -- "$cmd".
• Control keys: tmux -S "$SOCKET" send-keys -t target C-c.
• For interactive TUI apps like Claude Code/Codex, this guidance covers how to send commands.

Do not append Enter in the same send-keys. These apps may treat a fast text+Enter

sequence as paste/multi-line input and not submit; this is timing-dependent. Send text and

Enter as separate commands with a small delay (tune per environment; increase if needed,

or use sleep 1 if sub-second sleeps aren't supported):

```bash

tmux -S "$SOCKET" send-keys -t target -l -- "$cmd" && sleep 0.1 && tmux -S "$SOCKET" send-keys -t target Enter

```

• Capture recent history: tmux -S "$SOCKET" capture-pane -p -J -t target -S -200.
• Wait for prompts: {baseDir}/scripts/wait-for-text.sh -t session:0.0 -p 'pattern'.
• Attaching is OK; detach with Ctrl+b d.

• For python REPLs, set PYTHON_BASIC_REPL=1 (non-basic REPL breaks send-keys flows).

• tmux is supported on macOS/Linux. On Windows, use WSL and install tmux inside WSL.
• This skill is gated to darwin/linux and requires tmux on PATH.

tmux excels at running multiple coding agents in parallel:

```bash

SOCKET="${TMPDIR:-/tmp}/codex-army.sock"

# Create multiple sessions

for i in 1 2 3 4 5; do

tmux -S "$SOCKET" new-session -d -s "agent-$i"

done

# Launch agents in different workdirs

tmux -S "$SOCKET" send-keys -t agent-1 "cd /tmp/project1 && codex --yolo 'Fix bug X'" Enter

tmux -S "$SOCKET" send-keys -t agent-2 "cd /tmp/project2 && codex --yolo 'Fix bug Y'" Enter

# When sending prompts to Claude Code/Codex TUI, split text + Enter with a delay

tmux -S "$SOCKET" send-keys -t agent-1 -l -- "Please make a small edit to README.md." && sleep 0.1 && tmux -S "$SOCKET" send-keys -t agent-1 Enter

# Poll for completion (check if prompt returned)

for sess in agent-1 agent-2; do

if tmux -S "$SOCKET" capture-pane -p -t "$sess" -S -3 | grep -q "❯"; then

echo "$sess: DONE"

else

echo "$sess: Running..."

fi

done

# Get full output from completed session

tmux -S "$SOCKET" capture-pane -p -t agent-1 -S -500

```

Tips:

• Use separate git worktrees for parallel fixes (no branch conflicts)
• pnpm install first before running codex in fresh clones
• Check for shell prompt (❯ or $) to detect completion
• Codex needs --yolo or --full-auto for non-interactive fixes

• Kill a session: tmux -S "$SOCKET" kill-session -t "$SESSION".
• Kill all sessions on a socket: tmux -S "$SOCKET" list-sessions -F '#{session_name}' | xargs -r -n1 tmux -S "$SOCKET" kill-session -t.
• Remove everything on the private socket: tmux -S "$SOCKET" kill-server.

{baseDir}/scripts/wait-for-text.sh polls a pane for a regex (or fixed string) with a timeout.

```bash

{baseDir}/scripts/wait-for-text.sh -t session:0.0 -p 'pattern' [-F] [-T 20] [-i 0.5] [-l 2000]

```

• -t/--target pane target (required)
• -p/--pattern regex to match (required); add -F for fixed string
• -T timeout seconds (integer, default 15)
• -i poll interval seconds (default 0.5)
• -l history lines to search (integer, default 1000)
