分析ZIP文件的属性

我有一个ZIP文件，我想确定它的压缩方式（特定算法，用于应用该算法的属性，等等）。我怎样才能做到这一点？

zipinfo（来自InfoZIP）将告诉您很多有关文件的信息。

的示例输出zipinfo -v（使用“ verbose”选项-v）：

Archive:  /tmp/test.zip
There is no zipfile comment.

End-of-central-directory record:
-------------------------------

  Zip archive file size:                     22341 (0000000000005745h)
  Actual end-cent-dir record offset:         22319 (000000000000572Fh)
  Expected end-cent-dir record offset:       22319 (000000000000572Fh)
  (based on the length of the central directory and its expected offset)

  This zipfile constitutes the sole disk of a single-part archive; its
  central directory contains 1 entry.
  The central directory is 88 (0000000000000058h) bytes long,
  and its (expected) offset in bytes from the beginning of the zipfile
  is 22231 (00000000000056D7h).


Central directory entry #1:
---------------------------

  tmp/bookmarks.html

  offset of local header from start of archive:   0
                                                  (0000000000000000h) bytes
  file system or operating system of origin:      Unix
  version of encoding software:                   3.0
  minimum file system compatibility required:     MS-DOS, OS/2 or NT FAT
  minimum software version required to extract:   2.0
  compression method:                             deflated
  compression sub-type (deflation):               normal
  file security status:                           not encrypted
  extended local header:                          no
  file last modified on (DOS date/time):          2010 Feb 20 16:22:48
  file last modified on (UT extra field modtime): 2010 Feb 20 16:22:47 local
  file last modified on (UT extra field modtime): 2010 Feb 20 15:22:47 UTC
  32-bit CRC value (hex):                         3e84c75c
  compressed size:                                22155 bytes
  uncompressed size:                              76774 bytes
  length of filename:                             18 characters
  length of extra field:                          24 bytes
  length of file comment:                         0 characters
  disk number on which file begins:               disk 1
  apparent file type:                             text
  Unix file attributes (100600 octal):            -rw-------
  MS-DOS file attributes (00 hex):                none

  The central-directory extra field contains:
  - A subfield with ID 0x5455 (universal time) and 5 data bytes.
    The local extra field has UTC/GMT modification/access times.
  - A subfield with ID 0x7875 (Unix UID/GID (any size)) and 11 data bytes:
    01 04 e8 03 00 00 04 e8 03 00 00.

  There is no file comment.

如果这还不够，请说明您需要哪些信息。

请注意，zipinfo功能实际上是unzip程序的一部分（两个二进制文件通常是相同的，或彼此链接）。您可以调用unzip -Z以获取zipinfo的功能。因此，如果您的安装中不应包含zipinfo二进制文件，则可以使用二进制文件unzip -Z。

如info-zip档案文档中所述，该zipinfo命令实际上可以通过使用Windows命令运行unzip -Z。

使用以下命令创建“ zipinfo.bat”批处理文件：

unzip.exe -Zsvh %1

并且您已经zipinfo在Windows上运行。
