腻子 - 动态地使用C＃删除文件 [英] Putty - Delete files dynamically using C#

问题描述

我在一个Windows应用程序用C＃作为编程langugage工作。

要求

1. 要登录到动态腻子


2. 从特定位置删除旧文件

我目前使用下面的代码登录到腻子，但我怎么跑delete命令??

 字符串主机名=主机名; 
串登录=登录; 
字符串密码=密码; 
的ProcessStartInfo的StartInfo =新的ProcessStartInfo（）; 
 startInfo.FileName = @C：\Putty\putty.exe 
 startInfo.Arguments =的String.Format（{0} @ {1} -pw {2}，登录，主机名，密码）; 
 startInfo.Start（）; 
  

我想通过这样的事情

  RM MYFILE * .TXT 
  

但在此之前，我必须通过

  CD / DIR1 / DIR2 / NewFolder 
   
 
 
我想删除NewFolder ?? 
 
下的所有 .TXT 文件< DIV CLASS =h2_lin>解决方案

腻子有命令行选项的 -m {script_file} 它允许您指定要对远程服务器上运行一个脚本文件。所有的运行命令后，腻子将退出。

您可以保存命令脚本文件运行，调用腻子，并删除脚本文件，当你 。再完成

下面的代码对我的作品：

 字符串主机=主机名; 
串登录=登录; 
字符串密码=密码; 
字符串命令=RM〜/ DIR1 / DIR2 / NewFolder / * .TXT; //这个修改，以满足您的需求
 
常量字符串scriptFileName = @remote_commands.sh 
 File.WriteAllText（scriptFileName，命令）; 
 
变种的StartInfo =新的ProcessStartInfo（）; 
 startInfo.FileName = @C：\Putty\putty.exe 
 startInfo.Arguments =的String.Format（{0} @ {1} -pw {2} -m {3}，
登录，主机名，密码，scriptFileName）; 
 
 VAR过程=新的Process {StartInfo的=的StartInfo}; 
的Process.Start（）; 
 process.WaitForExit（）; 
 
 File.Delete（scriptFileName）; 
  

如果你想要做的就是发送一个命令到服务器，该解决方案就行了。如果您需要更多先进的功能，如读取服务器响应，你应该检查出托马斯的回答。

编辑：

下面是如何使用砰砰运行命令，并得到它们的输出：

 字符串主机=主机名; 
串登录=登录; 
字符串密码=密码; 
 
变种的StartInfo =新的ProcessStartInfo（）; 
 startInfo.FileName = @C：\Putty\plink.exe 
 startInfo.RedirectStandardInput = TRUE; 
 startInfo.RedirectStandardOutput = TRUE; 
 startInfo.UseShellExecute = FALSE; 
 startInfo.Arguments =的String.Format（{0} @ {1} -pw {2}，
登录，主机名，密码）;使用
 
（VAR过程=新的Process {StartInfo的=的StartInfo}）
 {
的Process.Start（）; 
 
 process.StandardInput.WriteLine（LS）; 
 process.StandardInput.WriteLine（回声运行多个命令在这里......'）; 
 process.StandardInput.WriteLine（退出）; //确保我们的出口在年底
 
字符串输出= process.StandardOutput.ReadToEnd（）; 
 Console.WriteLine（输出）; 
} 
  

I am working on a Windows app with C# as a programming langugage.

Requirement is

1. to login to putty dynamically
2. delete old files from specific location

I am currently using below code to login to putty, but how do i ran the delete command ??

string hostname = "hostname";
string login = "login";
string password = "password";
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = @"C:\Putty\putty.exe";
startInfo.Arguments = string.Format("{0}@{1} -pw {2}", login, hostname, password);
startInfo.Start();

I want to pass something like this

rm myFile*.txt

But before that I have to navigate to particular location by

cd /dir1/dir2/NewFolder

I wanted to delete all the .txt files under NewFolder??

解决方案

Putty has the command line option -m {script_file} which allows you to specify a script file to be run against the remote server. After all the commands are run, putty will exit.

You could save the command to be run in a script file, call Putty, and delete the script file when you're done.

The following code works for me:

string hostname = "hostname";
string login = "login";
string password = "password";
string command = "rm ~/dir1/dir2/NewFolder/*.txt"; // modify this to suit your needs

const string scriptFileName = @"remote_commands.sh";
File.WriteAllText(scriptFileName, command);

var startInfo = new ProcessStartInfo();
startInfo.FileName = @"C:\Putty\putty.exe";
startInfo.Arguments = string.Format("{0}@{1} -pw {2} -m {3}", 
                                     login, hostname, password, scriptFileName);

var process = new Process {StartInfo = startInfo};
process.Start();
process.WaitForExit();

File.Delete(scriptFileName);

If all you want to do is send a single command to the server, this solution will do. If you need more advanced functionality, like reading the server response, you should check out Thomas' answer.

Edit:

Here's how to use plink to run commands and get their output:

string hostname = "hostname";
string login = "login";
string password = "password";

var startInfo = new ProcessStartInfo();
startInfo.FileName = @"C:\Putty\plink.exe";
startInfo.RedirectStandardInput = true;
startInfo.RedirectStandardOutput = true;
startInfo.UseShellExecute = false;
startInfo.Arguments = string.Format("{0}@{1} -pw {2}",
                                        login, hostname, password);

using (var process = new Process {StartInfo = startInfo})
{
    process.Start();

    process.StandardInput.WriteLine("ls");
    process.StandardInput.WriteLine("echo 'run more commands here...'");
    process.StandardInput.WriteLine("exit"); // make sure we exit at the end

    string output = process.StandardOutput.ReadToEnd();
    Console.WriteLine(output);
}
