分割tar.bz2文件并分别提取每个文件 [英] Split tar.bz2 file and extract each individually

问题描述

我可以将一个较大的tar.bz2文件拆分为几个较小的文件，然后在Ubuntu中分别提取这些较小的tar.bz2文件吗?

谢谢

解决方案

我认为这不太容易. .tar.bz2 是单个流，它没有像 zip 这样的索引，该索引不允许跳至存档中特定文件的开头.您可以使用 split 实用程序拆分文件，然后使用 cat 拆分零件并将其提取(可以通过stdin进行操作，以避免在磁盘上重新创建粘贴的文件).可以单独提取第一个片段(最后一个文件可能会被损坏，但最后一个文件除外)，但是如果没有前面的片段，则其他片段将不可用.

Can I split a large tar.bz2 file into several smaller files and extract those small tar.bz2 files individually in Ubuntu?

Thanks,

解决方案

I don't think it's easily possible. A .tar.bz2 is a single stream, it doesn't have an index like zip that would allow skipping to the start of a particular file within the archive. You can split the file using split utility, and than cat the parts and extract them (you can do this via stdin to avoid re-creating the pasted file on disk). The first fragment will be possible to extract separately (except for the last file in it which will probably be damaged), but further fragments will not be usable without the onces that come before them.
