从命令行解压缩多部分 Zip

Question

预先感谢您的任何帮助。我正在尝试从 OSX 10.8.5 中的命令行解压缩多部分 zip 文件。

我使用创建了zipzip -s 800m foo.zip foo.mov

文件大小foo.mov为2.7GB。所以我有这些文件：foo.zip, foo.z01, foo.z02, foo.z03.

我尝试使用zip -s 0 foo.zip -O foo_unsplit.zip，但 foo_unsplit.zip 只有 1.6GB，并且在与 unzip 一起使用时出现以下错误。

error:  invalid compressed data to inflate

我也尝试使用cat Heritage.zip Heritage.z01 Heritage.z02 Heritage.z03 > Heritage_unsplit.zip但解压缩结果文件给出以下结果：

unzip Heritage_unsplit.zip 
Archive:  Heritage_unsplit.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of Heritage_unsplit.zip or
        Heritage_unsplit.zip.zip, and cannot find Heritage_unsplit.zip.ZIP, period.

有谁知道在命令行中解压缩多部分文件的方法。我的尝试是否犯了错误？

Answer 1

我假设 MacOS 版本之间的情况有所不同 - 我目前正在运行High Sierra 并且unzip仍然无法正确支持多部分 - 但我做了同样的技巧，cat但以相反的顺序，它起作用了。

即cat Heritage.z03 Heritage.z02 Heritage.z01 Heritage.zip > Heritage_unsplit.zip 然后unzip就可以了。

我遇到了一些如下错误，但文件是二进制的：

> unzip big.zip
Archive:  big.zip

  attempting to process anyway, assuming all parts have been concatenated
  together in order.  Expect "errors" and warnings...true multi-part support
  doesn't exist yet (coming soon).
