因为工作需要，平生第一次用Windows的Dos命令写脚本。
需求：本地有个软件，每天生成相应的Log文件，并保存在以日期时间为目录的文件夹下。然后需要在后一天，将前一天生成的Log文件及文件夹上传到一个日志服务器进行保存。
实现工具：bat脚本，Ncftp工具，计划任务
其中，因为系统默认的ftp命令行，不支持passive模式，而Port模式下，需要修改或开启Log生成端服务器的防火墙，需要最终改用网络上免费的小工具Ncftp，这个小工具比系统自带的强大了N倍，支持命令行，支持PASV模式也可以切换PORT模式，还支持断点续传，上传成功后删除本地文件等。
实现步骤：
1）转到脚本所在目录；
2）上传之前未能成功上传的文件；
3）取到今天需要上传的文件夹名称；
4）上传今天需要上传的文件夹及文件；
5）如果成功，删除本地文件，如果不成功，将文件夹移到备份目录；
6）删除空目录；
以下是具体的脚本内容（英文版系统）：
