我使用rsync以与服务器无关的方式将文件同步到Windows客户端。有哪些方法可以将rsync的进度发送到父进程以显示在gui进度栏中？

我想象有两个或者三个选择。 (1)观察STDOUT(2)观察rsync.exe日志文件，类似于unixtail(3)观察内存中的rsync控制台输出。

哪个是最好的/首选的？

解决方案

回答

.NET具有一种非常简单的读取和观看STDOUT的方式。
我猜这将是最干净的方法，因为它不依赖于任何外部文件，而仅依赖于rsync的路径。如果那里也有包装器库，我也不会太惊讶。如果没有，请编写并开源：)

签出DeltaCopy。这是用于rsync的Windows GUI。

对于此类任务，我使用自己的AutoIt脚本(免费软件，仅Windows)。该脚本将标准输出重定向到图形窗口，并具有向后滚动等功能显示它(在诸如XCOPYs / PKZIPs这样的长过程中，如果检查是否发生任何错误，这非常有用)。

我使用AutoIt是因为它是免费的，非常易于使用，并且可以快速编译为.EXE。我认为，对于此类任务，它是完整编程语言的绝佳替代品。缺点是仅适用于Windows。

$sCmd = "DIR E:\*.AU3 /S"  ; Test command
$nAutoTimeout = 10      ; Time in seconds to close window after finish

$nDeskPct = 60          ; % of desktop size (if percent)

; $nHeight = 480          ; height/width of the main window (if fixed)
; $nWidth = 480

$sTitRun = "Executing process. Wait...."     ; 
$sTitDone = "Process done"                ; 

$sSound = @WindowsDir & "\Media\Ding.wav"       ; End Sound

$sButRun = "Cancel"                           ; Caption of "Exec" button
$sButDone = "Close"                            ; Caption of "Close" button

我为此构建了自己的简单对象，我从中获得了很多可重用性，我可以使用cmdline，web页面，webservice将其包装，将输出写入文件，等等-

注释的项目包含一些rsync示例-

我有时想做的是将rsync(和cygwin)嵌入到资源中，并从中创建一个.net可执行文件，

干得好：

Imports System.IO

Namespace cds

Public Class proc

    Public _cmdString As String
    Public _workingDir As String
    Public _arg As String

    Public Function basic() As String

        Dim sOut As String = ""

        Try
            'Set start information.
            'Dim startinfo As New ProcessStartInfo("C:\Program Files\cwRsync\bin\rsync", "-avzrbP 192.168.42.6::cdsERP /cygdrive/s/cdsERP_rsync/gwy")

            si.WorkingDirectory = _workingDir

            ' Make the process and set its start information.
            Dim p As New Process()
            p.StartInfo = si

            ' Start the process.
            p.Start()

            ' Attach to stdout and stderr.
            Dim stdout As StreamReader = p.StandardOutput()
            Dim stderr As StreamReader = p.StandardError()

            sOut = stdout.ReadToEnd() & ControlChars.NewLine & stderr.ReadToEnd()

            'Dim writer As New StreamWriter("out.txt", FileMode.CreateNew)
