您如何在1个终端命令中同时运行客户端和服务器命令

Question

我有2条命令

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    if let slSheet = self.children.first as? UINavigationController {

        // Change color of Cancel and Post Button
        slSheet.navigationBar.tintColor = .orange

        // All contents of botton view are loaded inside table view at specific level of child view
        if let tblView = slSheet.children.first?.view.subviews.first as? UITableView,
            let firstCell = tblView.visibleCells.first
        {

            // Enumerate on subViews of contentView

            for (index, label) in firstCell.contentView.subviews.enumerated() {

                if index == 0 {

                    // Left label
                    if let lblLeft = label as? UILabel {
                        lblLeft.font = UIFont(name: "Helvetica-Bold", size: 20)
                        lblLeft.textColor = .orange
                    }

                } else {

                    // Right label
                    if let lblRight = label as? UILabel {
                        lblRight.font = UIFont(name: "Helvetica", size: 14)
                        lblRight.textColor = .green
                    }
                }
            }
            // Reload table if label not loading properly
            tblView.reloadData()
        }
    }
}

我想去终端，运行1 bash别名来启动这两个。但是我不能做

npm run server-start

npm run react-start

因为第一个命令连续运行。我正在运行iterm2。我知道我可以打开2个窗口，但是我想创建一个超级简单的别名并一起运行。如果需要的话，这是在Mac上。
