Windows批处理脚本从FTP下载无最新的文件并把它们喂到一个EXE文件 [英] Windows Batch script to download N latest files from FTP and feed them to an EXE file

问题描述

我比较熟悉Bash和Bash中我在做什么在这里会很容易。

I am more familiar with Bash and in Bash what I am doing here would be easy.

我想创建一个Windows批处理脚本从FTP服务器上下载文件名N个最新的文件，然后输送到一个EXE作为命令行参数。

I would like to create a Windows batch script to download the N latest files from an FTP server and then feed the filenames to an EXE as command line parameters.

在code会做以下几点：

The code would be doing the following:

open ftp test.com
username
password
"get/download N latest files from the ftp folder" 
"list N latest files just downloaded"
"for each filename execute 'mytest.exe filename' as a background job (in Bash: &)"

我认为，异步运行过程中，我可以使用START命令。

I think that to run a process asynchronously, I can use the START command.

这怎么使用批处理脚本或命令行来实现？

How can this be achieved using a Batch script or the command line?

推荐答案

您可以使用以下使用PowerShell脚本的WinSCP .NET程序集：

You can use following PowerShell script using WinSCP .NET assembly:

param (
    $sessionUrl = "ftp://user:[e-mail]/",
    $localPath = "c:\\downloaded\\",
    $remotePath = "/home/user/",
    $count = 10
)

# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"

# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions
$sessionOptions.ParseUrl($sessionUrl);

$session = New-Object WinSCP.Session

# Connect
$session.Open($sessionOptions)

# Get list of files in the directory
$directoryInfo = $session.ListDirectory($remotePath)

# Select the most recent file
$latestFiles =
    $directoryInfo.Files |
    Where-Object { -Not $_.IsDirectory } |
    Sort-Object LastWriteTime -Descending |
    Select-Object -First $count

# Download the latest files
foreach ($latestFile in $latestFiles)
{
    Write-Host ("Downloading {0}..." -f $latestFile)

    $session.GetFiles($session.EscapeFileMask($remotePath + $latestFile.Name), $localPath).Check()
}

# Disconnect, clean up
$session.Dispose()

这是基于一个正式的例子下载最新的文件。

This is based on an official example Downloading the most recent file.
