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 | |
| (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): 2022 Oct 16 23:38:58 | |
| file last modified on (UT extra field modtime): 2022 Oct 16 23:38:57 local | |
| file last modified on (UT extra field modtime): 2022 Oct 16 15:38:57 UTC | |
| 32-bit CRC value (hex): 8df494ab | |
| compressed size: 554 bytes | |
| uncompressed size: 1333 bytes | |
| length of filename: 10 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 (100644 octal): -rw-r--r-- | |
| 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 00 00 00 00 04 00 00 00 00. | |
| There is no file comment. |
