## 创建tmux
function create(){
    tmux new-session -d -s update
    tmux split-window -h -t update -p 30
    for((index=0; index<$(($PANE_NUM-1));index++)); do
        percent=$(( 100  / ($PANE_NUM - $index) ))
        tmux split-window -v -t update:0.0 -p $percent
    done
    tmux send-keys -t update:0.1 "bash ${LOCAL_FILE}" C-m
    tmux send-keys -t update:0.1 "bash ${LOCAL_FILE} send all 'clear'" C-m
    tmux send-keys -t update:0.1 "bash ${LOCAL_FILE} confirm" C-m
}

## 发送消息
function send(){
    panes=$1
    cmd="$2"
    case $panes in
        "all")
            send_all "${cmd}";;
        *)
            send_one "$panes" "$cmd";;
    esac
}

function send_one(){
    pane=$1
    cmd="$2"
    tmux send-keys -t update:0.$pane "${cmd}"
}

function send_all(){
    cmd="$1"
    for((index=0; index<=$PANE_NUM; index++));do
        if [[ $index -ne 1 ]]; then
            tmux send-keys -t update:0.$index "${cmd}"
        fi
    done
}

## 确认
function confirm(){
    send all "C-m"
}
