如何在终端中解压多部分zip文件？

Question

鉴于 img.zip 包含同一张照片的 13 个副本，我需要将 zip 文件拆分为多个部分，并能够从生成的部分中将其解压缩。为了将其分割为 100KB 的部分，我这样做：

zip img.zip --out img-pt -s 100k

导致

100K    img-pt.z01
100K    img-pt.z02
100K    img-pt.z03
 40K    img-pt.zip

我可以在 macOS 上使用 keka 从生成的部分中提取内容。但是，我无法使用

unzip

解压缩，这是我尝试得到的结果：

>>> unzip img-pt.zip
Archive:  img-pt.zip
warning [img-pt.zip]:  zipfile claims to be last disk of a multi-part archive;
  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).

还有

>>> cat img-pt.z01 img-pt.z02 img-pt.z03 img-pt.zip > img.zip
>>> unzip img.zip
Archive:  img.zip

如何在终端中提取文件而不出现错误？并且最好不要连接各个部分

Answer 1

将所有文件

.z*

和

.zip

放入同一目录并使用以下命令：

zip -s- img-pt.zip -O combined.zip
unzip combined.zip

Answer 2

如果您正在处理大文件，您可以使用 7zip 直接提取，而无需合并各个部分：

7z x img-pt.zip

这将立即开始提取。
