Question

我有一个批处理文件，每5分钟由一个预定的Windows服务执行。批处理文件为特定的文件掩码执行mget：* .ext。在mget之后它会执行mdel * .ext。最近我遇到了一个问题：当在mget和mdel的执行之间创建文件z.ext时，该文件被删除但是它不在mget中。当然这是有道理的。所以现在我正在寻找适当的Windows ftp命令，它们将遍历文件并按文件执行mget和mdel文件。这可能吗？

ftp scriptng非常有限，但我认为你可以使用this approach。基本上，你必须运行ftp两次，首先收集要下载的文件列表，然后第二次下载（和删除）每个文件（结合大量的cmd脚本）你仍然没有得到任何错误处理和ftp服务器的容错性并不完全清楚。

上述网站的相关示例是：

REM -- Define File Filter, i.e. files with extension .txt
Set FindStrArgs=/E /C:".txt"

REM -- Extract Ftp Script to create List of Files
Set "FtpCommand=ls"
Call:extractFileSection "[Ftp Script 1]" "-">"%temp%\%~n0.ftp"
Rem Notepad "%temp%\%~n0.ftp"

REM -- Execute Ftp Script, collect File Names
Set "FileList="
For /F "Delims=" %%A In ('"Ftp -v -i -s:"%temp%\%~n0.ftp"|Findstr %FindStrArgs%"') Do (
    Call Set "FileList=%%FileList%% "%%A""
)

REM -- Extract Ftp Script to download files that don't exist in local folder
Set "FtpCommand=mget"
For %%A In (%FileList%) Do If Not Exist "%%~A" Call Set "FtpCommand=%%FtpCommand%% "%%~A""
Call:extractFileSection "[Ftp Script 1]" "-">"%temp%\%~n0.ftp"
Rem Notepad "%temp%\%~n0.ftp"

For %%A In (%FtpCommand%) Do Echo.%%A

可能更好地在python或其他一些脚本环境中执行此操作（假设您没有部署问题。）

使用bat文件循环访问FTP目录中的文件
