zipinfo – Used to List Compressed File Information

The zipinfo command is a Linux utility that is used to list the contents of a compressed file. It displays the information about the files that are stored inside a compressed archive file, such as the file name, size, date, and time of creation, and the compression ratio.

Overview

The basic syntax of the zipinfo command is:

zipinfo [options] archive.zip

Here, archive.zip is the name of the compressed archive file that you want to analyze. The zipinfo command can be used with several options to display different types of information about the compressed file.

Examples

  1. To display the contents of a compressed file, run the following command: 
    zipinfo archive.zip

    This will display the list of files and directories that are stored inside the archive.zip file.

  2. To display the detailed information about a specific file in the compressed archive, run the following command: 
    zipinfo -m archive.zip file.txt

    This will display the information about the file.txt file that is stored inside the archive.zip file, including the file size, date and time of creation, and the compression ratio.

  3. To display the summary information about the compressed archive, run the following command: 
    zipinfo -s archive.zip

    This will display the summary information about the archive.zip file, including the number of files, compressed size, uncompressed size, and the compression ratio.

The following table lists the available options for the zipinfo command:
