I use rsync to synchronize files to Windows clients in a server agnostic way. What methods are available to send the progress of rsync to the parent process for display in a gui progress bar?
I imagine two or three choices exist. (1) Watch STDOUT (2) Watch rsync.exe log file, similar to unix tail (3) Watch rsync console output in memory.
Which one is best/preferred?
.NET has a pretty straight forward way to read and watch STDOUT.
I guess this would be the cleanest way, since it is not dependent on any external files, just the path to rsync. I would not be too surprised if there is a wrapper library out there either. If not, write and open source it :)
Check out I think it is called DeltaCopy. It is a windows gui for rsync (i believe)
Looked it up. DeltaCopy http://www.download.com/DeltaCopy/3000-2242_4-10471616.html
For this type of tasks, I use my own AutoIt script (freeware, Windows only). The script redirects the standard output into a graphical window, displaying it with the ability to scroll back, etc (very useful in long processes like XCOPYs / PKZIPs to check if any error did happen).
I use AutoIt because it's free, very easy to use, and can compile quickly into an .EXE. I think it's an excellent alternative to a complete programming language for this type of tasks. The downside is that it's for Windows only.

Hello:
I've built my own simple object for this, i get alot or reuse out of it, i can wrap it with a cmdline, web page, webserice, write output to a file, etc---
the commented items contain some rsync examples--
what i'd like to do sometime is embed rsync (and cygwin) into a resource & make a single .net executable out of it--
Here you go:
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")
'Dim startinfo As New ProcessStartInfo("C:\Program Files\cwRsync\bin\rsync", "-avzrbP 10.1.1.6::user /cygdrive/s/cdsERP_rsync/gws/user")
'Dim startinfo As New ProcessStartInfo("C:\windows\system32\cscript", "//NoLogo c:\windows\system32\prnmngr.vbs -l")
Dim si As New ProcessStartInfo(_cmdString, _arg)
si.UseShellExecute = False
si.CreateNoWindow = True
si.RedirectStandardOutput = True
si.RedirectStandardError = True
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)
'writer.Write(sOut)
'writer.Close()
stdout.Close()
stderr.Close()
p.Close()
Catch ex As Exception
sOut = ex.Message
End Try
Return sOut
End Function
End Class
