windows windows符号链接目标

windows symbolic link target

提问by Sree Ram

Say that I set up a symbolic link:

假设我设置了一个符号链接：

mklink  /D C:\root\Public\mytextfile.txt C:\root\Public\myothertextfile.txt

^{Editor's note: Option /D- which is for creating directorysymlinks - is at odds with targeting files, as in this example, which has caused some confusion. To create a filesymlink, simply omit /D.}

^{编者注：Option /D- 用于创建目录符号链接 - 与定位文件不一致，如本例所示，这引起了一些混淆。要创建文件符号链接，只需省略/D.}

Is there a way to see what the target of mytextfile.txtis, using the command line?

有没有办法mytextfile.txt使用命令行查看目标是什么？

As Harry Johnston said dircommand shows the target of symbolic links

正如哈里约翰斯顿所说，dir命令显示符号链接的目标

To complement Paul Verest's helpful answer:

为了补充Paul Verest 的有用回答：

• While cmd's dirindeed shows the link type and target path, extractingthat information is nontrivial - see below for a PowerShell alternative.

• In order to discover all links in the current directory, use dir /aL.

• 虽然cmd'sdir确实显示了链接类型和目标路径，但提取该信息并不重要 - 请参阅下面的 PowerShell 替代方案。

• 要发现当前目录中的所有链接，请使用dir /aL.

PowerShell(PSv5+) solutions:

PowerShell(PSv5+) 解决方案：

List all links and their targets in the current directory as full paths:

将当前目录中的所有链接及其目标列为完整路径：

PS> Get-ChildItem | ? Target | Select-Object FullName, Target

FullName                      Target
--------                      ------
C:\root\public\mytextfile.txt {C:\root\Public\myothertextfile.txt}

Determine a given link's target:

确定给定链接的目标：

PS> (Get-Item C:\root\Public\mytextfile.txt).Target
C:\root\Public\myothertextfile.txt

Write a batch file( get_target.bat) to get the target of the symbolic link:

编写一个批处理文件（get_target.bat）来获取符号链接的目标：

@echo off
for /f "tokens=2 delims=[]" %%H in  ('dir /al %1 ^| findstr /i /c:"%2"') do (
    echo %%H
)

For example, to get the target of C:\root\Public\mytextfile.txt:

例如，要获得目标C:\root\Public\mytextfile.txt：

get_target.bat C:\root\Public\ mytextfile.txt

Maybe someone's interested in a C# method to resolve all directory symlinks in a directory similar to Directory.GetDirectories(). To list Junctions or File symlinks, simply change the regex.

也许有人对解析类似于 Directory.GetDirectories() 的目录中的所有目录符号链接的 C# 方法感兴趣。要列出连接点或文件符号链接，只需更改正则表达式。

static IEnumerable<Symlink> GetAllSymLinks(string workingdir)
{
    Process converter = new Process();
    converter.StartInfo = new ProcessStartInfo("cmd", "/c dir /Al") { RedirectStandardOutput = true, UseShellExecute = false, CreateNoWindow = true, WorkingDirectory = workingdir };
    string output = "";
    converter.OutputDataReceived += (sender, e) =>
    {
        output += e.Data + "\r\n";
    };
    converter.Start();
    converter.BeginOutputReadLine();
    converter.WaitForExit();

    Regex regex = new Regex(@"\n.*\<SYMLINKD\>\s(.*)\s\[(.*)\]\r");

    var matches = regex.Matches(output);
    foreach (Match match in matches)
    {
        var name = match.Groups[1].Value.Trim();
        var target = match.Groups[2].Value.Trim();
        Console.WriteLine("Symlink: " + name + " --> " + target);

        yield return new Symlink() { Name = name, Target = target };
    }
}

class Symlink
{
    public string Name { get; set; }
    public string Target { get; set; }
}
