Question

如何在PowerShell会话中输入“是”作为交互式问题的答案？我知道，在Bash中，Yes是在提示符上回答“是”的工具。在我的情况下，我无法抑制提示。

我正在运行的脚本停在

如果您想继续，请回复“是”：

powershell如何运行脚本并在提示时“回答”是？

Answer 1

您可以测试这些旧时尚方式：

Cmd /c "GpUpdate.exe /FORCE <C:\temp\response.txt"

ECHO 'Y' | GpUpdate.exe /FORCE

Get-Content "C:\temp\response.txt" | GpUpdate.exe /FORCE

Answer 2

使用ECHO为我工作。我在我的Powershell脚本中运行RSKeyMgmt.exe，它提示是（Y）/否（N）。所以当我做的时候

ECHO Y | RSKeyMgmt.exe...

它没有提示问题，命令执行正确。

所以我认为ECHO 'someoption'也适用于其他案例。

Answer 3

我也遇到了同样的问题。我尝试的解决方案包括：

ECHO'Y'|
命令名称-强制
$ ConfirmPreference ='无'

但是，他们似乎都没有做到这一点。

最终解决问题的是：

Powershell-Cmdlet -Confirm:$false

在命令执行期间，它将取消所有确认提示，并且将在不进行任何确认的情况下处理命令。

受其他答案的启发，这是我的示例：

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
        primarySwatch: Colors.blue,
      ),
      home: DataTableDemo(),
    );
  }
}



class User {
  String firstName;
  String lastName;

  User({this.firstName, this.lastName});

  static List<User> getUsers() {
    return <User>[
      User(firstName: "Aaryan", lastName: "Shah"),
      User(firstName: "Ben", lastName: "John"),
      User(firstName: "Carrie", lastName: "Brown"),
      User(firstName: "Deep", lastName: "Sen"),
      User(firstName: "Emily", lastName: "Jane"),
    ];
  }
}

class DataTableDemo extends StatefulWidget {
  DataTableDemo() : super();

  final String title = "Data Table Flutter Demo";

  @override
  DataTableDemoState createState() => DataTableDemoState();
}

class DataTableDemoState extends State<DataTableDemo> {
  List<User> users;
  List<User> selectedUsers;
  bool sort;

  @override
  void initState() {
    sort = false;
    selectedUsers = [];
    users = User.getUsers();
    super.initState();
  }

  onSortColum(int columnIndex, bool ascending) {
    if (columnIndex == 0) {
      if (ascending) {
        users.sort((a, b) => a.firstName.compareTo(b.firstName));
      } else {

Answer 5

以下 Powershell 对我有用：

Write-Output 'Y' | .\plink.exe <ip_address> -l <username> -pw <password>

这会将“Y”字符输出到下一个管道对象。

Answer 6

我在尝试使用时遇到了同样的问题：

net use * /delete

它总是促使我选择 Y/N 并尝试了这里的解决方案，但没有奏效，所以我报告了对我有用的方法：

net use * /delete /y

也许每个命令都有一个无声确认。

Answer 7

我试图杀死一个讨厌的启动程序，发现Stop-Process和/或该程序将不接受管道输入（对我来说没有Echo Y |！），但是我更改了JP的回答：Stop-进程名[program.name] -Force;以管理员身份运行，它像一种魅力。

如何在Powershell中自动回答“是”？
