【问题描述】：
给定包含同一张照片的 13 个副本的 img.zip，我需要将 zip 文件拆分成多个部分，并能够从生成的部分中解压缩它。要将它拆分为相等的 100KB 部分，我会这样做：
zip img.zip --out img-pt -s 100k
这导致
100K img-pt.z01
100K img-pt.z02
100K img-pt.z03
40K img-pt.zip
我能够在 macOS 上使用 keka 从生成的部分中提取。但是，我无法使用unzip 解压缩，这是我尝试得到的：
>>> 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
>>> cat img-pt.z01 img-pt.z02 img-pt.z03 img-pt.zip > img.zip
>>> unzip img.zip

如何在没有错误的情况下提取终端中的文件？并且最好不要连接部件
【问题讨论】：
-
该程序告诉你期待错误和警告，因为你正在做一些它不完全支持的事情......
-
然而它支持拆分成多个部分，我觉得这很奇怪
-
见the manpage的BUGS部分第一段
-
看起来我需要在连接的部分上使用
zip -F，直到他们修复下一个版本中的任何错误。
