快速从ftp下载最新软件包的批处理脚本

背景
客户端放置在一个公共的ftp上面。每天频繁登陆ftp下载，或者使用ftp工具，每次都要点击同步，都不太方便。如果在linux下就好了，然而在windows也是可以运行脚本的，何不尝试下呢。

1. @echo off
   
2. rem for download file
   
3. rem ftp config
   
4. rem ip login_name password remote_dir
   
5. 
   
6. set "ftp_ip=192.168.0.1"
   
7. set "ftp_user=admin"
   
8. set "ftp_pass=123456"
   
9. set "ftp_path=/"
   
10. 
    
11. set "f_tmp=tmp"
    
12. set "f_info=tmp\tmp_info.dat"
    
13. set "f_list=tmp\tmp_list.dat"
    
14. 
    
15. rd /s /q pack
    
16. mkdir %f_tmp%
    
17. 
    
18. echo open %ftp_ip% > %f_info%
    
19. echo user %ftp_user% >> %f_info%
    
20. echo %ftp_pass%>> %f_info%
    
21. echo prompt >> %f_info%
    
22. echo binary >> %f_info%
    
23. echo cd %ftp_path% >> %f_info%
    
24. echo ls . %f_list% >> %f_info%
    
25. echo lcd %f_tmp% >> %f_info%
    
26. echo disconnect >> %f_info%
    
27. echo bye >> %f_info%
    
28. 
    
29. ftp -v -n -s:%f_info%
    
30. 
    
31. 
    
32. for /f "delims=" %%i in ('type "%f_list%"') do (
    
33.     set "target_7z=%%i"
    
34. )
    
35. 
    
36. echo open %ftp_ip% > %f_info%
    
37. echo user %ftp_user% >> %f_info%
    
38. echo %ftp_pass%>> %f_info%
    
39. echo prompt >> %f_info%
    
40. echo binary >> %f_info%
    
41. echo cd %ftp_path% >> %f_info%
    
42. echo lcd %f_tmp% >> %f_info%
    
43. echo get %target_7z%>> %f_info%
    
44. echo disconnect >> %f_info%
    
45. echo bye >> %f_info%
    
46. 
    
47. ftp -v -n -s:%f_info%
    
48. 
    
49. call tools\7z\x64\7za.exe x %f_tmp%\%target_7z%
    
50. 
    
51. rd /s /q %f_tmp%
    
52. 
    
53. exit

获取文件列表：

1. echo open %ftp_ip% > %f_info%
   
2. echo user %ftp_user% >> %f_info%
   
3. echo %ftp_pass%>> %f_info%
   
4. echo prompt >> %f_info%
   
5. echo binary >> %f_info%
   
6. echo cd %ftp_path% >> %f_info%
   
7. echo ls . %f_list% >> %f_info%
   
8. echo lcd %f_tmp% >> %f_info%
   
9. echo disconnect >> %f_info%
   
10. echo bye >> %f_info%
    
11. 
    
12. ftp -v -n -s:%f_info%

复制代码

这部分代码主要有以下几个作用：

将ftp的命令写入到文件；
在ftp上获取对应目录的文件列表，并写到本地文件下。
for /f "delims=" %%i in ('type "%f_list%"') do (
    set "target_7z=%%i"
)

下载最新文件：
echo open %ftp_ip% > %f_info%
echo user %ftp_user% >> %f_info%
echo %ftp_pass%>> %f_info%
echo prompt >> %f_info%
echo binary >> %f_info%
echo cd %ftp_path% >> %f_info%
echo lcd %f_tmp% >> %f_info%
echo get %target_7z%>> %f_info%
echo disconnect >> %f_info%
echo bye >> %f_info%

ftp -v -n -s:%f_info%
有了文件名，我们就可以再执行一次ftp命令，下载我们最新的文件了。以上就实现了动态下载最新文件了。
call tools\7z\x64\7za.exe x %f_tmp%\%target_7z%

学习了，谢谢分享。

还不错，可以尝试一下。
