# 1.命令简介
zipinfo（zip information）列出有关 ZIP 存档的详细信息。
# 2.命令格式
zipinfo [-12CsmlvhMtTz] <file>[<.zip>] [<file(s)> ...] [-x <xfile(s)> ...]
# 3.选项说明
-1
只列出文件名称。
-2
此参数的效果和指定“-1”参数类似，但可搭配“-h”，“-t”和“-z”参数使用。
-h
列出首行信息，打印存档名称、实际大小（字节）和文件总数。
-l
此参数的效果和指定“-m”参数类似，但会列出原始文件的大小而非每个文件的压缩率。
-m
此参数的效果和指定“-s”参数类似，但多会列出每个文件的压缩率。
-M
若信息内容超过一个画面，则采用类似more指令的方式列出信息。
-s
用类似执行“ls-l”指令的效果列出压缩文件内容。
-t
只列出压缩文件内所包含的文件数目，压缩前后的文件大小及压缩率。
-T
将压缩文件内每个文件的日期时间用年，月，日，时，分，秒的顺序列出。
-v
详细显示压缩文件内每一个文件的信息。
-x xfile(s)
不列出符合条件的文件信息。
-z
如果压缩文件内含有注释，就将注释显示出来。
# 4.常用示例
我们先对 /etc/passwd 使用 zip 进行压缩。
zip passwd.zip /etc/passwd
adding: etc/passwd (deflated 58%)
（1）显示 zip 文件信息。
zipinfo passwd.zip
Archive: passwd.zip
Zip file size: 724 bytes, number of entries: 1
-rw-r--r-- 3.0 unx 1333 tx defN 22-Oct-16 23:38 etc/passwd
1 file, 1333 bytes uncompressed, 554 bytes compressed: 58.4%
（2）只显示压缩包名称、大小和文件数目。
zipinfo -h passwd.zip
Archive: passwd.zip
Zip file size: 724 bytes, number of entries: 1
（3）详细显示压缩文件内每一个文件的信息。
zipinfo -v passwd.zip
Archive: passwd.zip
There is no zipfile comment.
End-of-central-directory record:
-------------------------------
Zip archive file size: 724 (00000000000002D4h)
Actual end-cent-dir record offset: 702 (00000000000002BEh)
Expected end-cent-dir record offset: 702 (00000000000002BEh)
(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 80 (0000000000000050h) bytes long,
and its (expected) offset in bytes from the beginning of the zipfile
is 622 (000000000000026Eh).
Central directory entry #1:
---------------------------
etc/passwd
offset of local header from start of archive: 0

minimum file system compatibility required: MS-DOS, OS/2 or NT FAT
minimum software version required to extract: 2.0

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:
