我是靠谱客的博主调皮诺言，最近开发中收集的这篇文章主要介绍批处理bat下载FTP服务器上指定天数之前的文件，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

@echo off
rem 指定FTP用户名
set ftpUser=asx
rem 指定FTP密码
set ftpPass=asx-asx
rem 指定FTP服务器地址
set ftpIP=172.19.103.7
rem 指定待下载的文件位于FTP服务器的什么位置
set ftpFolder=/export/home/PROD/ntcdata
rem 指定从FTP下载下来的文件存放到什么地方
set LocalFolder=E:/Temp
rem 指定下载几天前的文件
set DaysAgo=1
set ftpDir=%temp%/TempDir.txt
set ftpDown=%temp%/TempDown.txt

rem 假设本机日期格式为yyyy-mm-dd
set FileY=%date:~0,4%
call :DateToDays %date:~0,4% %date:~5,2% %date:~8,2% PassDays
set /a PassDays-=DaysAgo
call :DaysToDate %PassDays% DstYear DstMonth DstDay

>>"%ftpDir%" echo cd "%ftpFolder%"
>>"%ftpDir%" echo dir * "%temp%/FileList.txt"
>>"%ftpDir%" echo bye
start ftp -v -i -s:"%ftpDir%" %ftpIP%

rem 根据实际情况自行调节延迟时间
