infometa tmux Skill
Use tmux only when you need an interactive TTY. Prefer bash background mode for long-running, non-interactive tasks.
Quickstart (isolated socket)
SOCKET_DIR="${TMPDIR:-/tmp}/codebuddy-tmux-sockets"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/codebuddy.sock"
SESSION=codebuddy-python
tmux -S "$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
Socket convention
- Default socket dir:
${TMPDIR:-/tmp}/codebuddy-tmux-sockets - Default socket path:
"$SOCKET_DIR/codebuddy.sock"
Targeting panes
- Target format:
session:window.pane(defaults to:0.0) - Keep names short; avoid spaces.
Finding sessions
- List sessions:
{baseDir}/scripts/find-sessions.sh -S "$SOCKET" - Scan all sockets:
{baseDir}/scripts/find-sessions.sh --all
Sending input safely
- Literal sends:
tmux -S "$SOCKET" send-keys -t target -l -- "$cmd" - Control keys:
tmux -S "$SOCKET" send-keys -t target C-c
Watching output
- Capture recent:
tmux -S "$SOCKET" capture-pane -p -J -t target -S -200 - Wait for prompts:
{baseDir}/scripts/wait-for-text.sh -t session:0.0 -p 'pattern'
Cleanup
- Kill session:
tmux -S "$SOCKET" kill-session -t "$SESSION" - Kill all:
tmux -S "$SOCKET" kill-server
Helper: wait-for-text.sh
{baseDir}/scripts/wait-for-text.sh -t session:0.0 -p 'pattern' [-F] [-T 20] [-i 0.5] [-l 2000]
