Linux zipinfo command

Linux Command大全

The Linux zipinfo command is used to list information about the compressed file.

Executing the zipinfo command can obtain detailed information about the zip compressed file.

Syntax

zipinfo [-12hlmMstTvz][Compressed File][File...][-x <template style>]

Parameter:

• -1 Only list file names.
• -2 The effect of this parameter is similar to specifying"-1"parameter is similar, but it can be combined with"-h","-t"and"-z"parameter usage.
• -h Only list the file names of the compressed file.
• -l The effect of this parameter is similar to specifying"-m"parameter is similar, but it will list the original file size instead of the compression rate of each file.
• -m The effect of this parameter is similar to specifying"-s"parameter is similar, but it will list the compression rate of each file more often.
• -M If the information content exceeds one screen, list the information in a way similar to the more command.
• -s Similar to executing "ls -l"command effect lists the content of the compressed file.
• -t Only list the number of files contained in the compressed file, the size before and after compression, and the compression rate.
• -T List the date and time of each file in the compressed file in the order of year, month, day, hour, minute, and second.
• -v Display detailed information of each file in the compressed file.
• -x<template style> Do not list information of files that meet the conditions.
• -z If the compressed file contains comments, display the comments.

Display information of each file in the compressed file

[[email protected] a]# zipinfo -v cp.zip 
Archive: cp.zip  486 bytes  4 files
End-of-central-directory record:
-------------------------------
 Actual offset of end-of-central-dir record:     464 (000001D0h)
 Expected offset of end-of-central-dir record:    464 (000001D0h)
 (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 4 entries. The central directory is 248
 (000000F8h) bytes long, and its (expected) offset in bytes from the
 beginning of the zipfile is 216 (000000D8h).
 There is no zipfile comment.
