在Windows命令提示符上管道数据 [英] Piping data on Windows command prompt

问题描述

我需要获得一个大（〜8gb）svn存储库的备份转储。我当前的方法涉及使用 svnadmin dump 到文件，然后使用7-Zip压缩和拆分该文件。

I need to get a backup dump of a large (~8gb) svn repository. My current method involves using svnadmin dump to a file and then using 7-Zip to compress and split the file.

> svnadmin dump c:\path\to\myrepo > c:\svndump.svn
> 7z svndump.svn svndump.7z      // or whatever the correct syntax is

是一种方法跳过中间人在这里，并得到的svn转储数据被压缩在一起使用管道或东西？这可能吗？

I was wondering if there would be a way to skip the middle-man here, and get the svn dump data to be compressed in one go by using pipes or something? Is this possible? What would the syntax be?

推荐答案

svnadmin dump 默认转储到标准版和 7z 命令行可以使用 / code> switch 。

svnadmin dump dumps to standard out by default and the 7z command line can read from standard input using the -si switch.

svnadmin dump c:\path\to\myrepo | 7z a -si svndump.7z
