How to display compressed file information in Linux?

In Linux systems, compressed files are usually used to save disk space or package files for transmission. To view the information of compressed files, you can use some commands to display the basic information of compressed files, file list, compression algorithm and other information. The following will introduce how to use common compressed file formats (such as zip, tar, gzip) in Linux systems to display compressed file information.

View zip file information

First, let’s look at how to view zip file information. Zip is a common compression format. You can use the unzip command on a Linux system to decompress and view the contents of a zip file. To display information about a zip file, you can use the unzip -l command, for example:

unzip -l file.zip

This will list all files and folders contained in the zip file, along with their sizes and modifications Date and other information.

View tar file information

Another common compression format is tar, which is often combined with gzip to create a tar.gz file. To view the information of the tar file, you can use the tar -tvf command, for example:

tar -tvf file.tar

This will list all files and folders contained in the tar file, as well as their permissions, ownership author, size, and modification date.

View gzip file information

Gzip is a common single file compression format. On Linux systems, you can use the gzip -l command to display gzip file information. For example:

gzip -l file.gz

This will display the compression ratio of the gzip file, the file size before and after compression and other information.

View other compression format information

For some other compression formats, we can also use corresponding tools to display compressed file information. For example, for the bzip2 compression format, you can use the bzip2 -tv command to display the bzip2 file information.

In short, in the Linux system, we can display the information of various compressed files through appropriate commands to help us understand the contents of the compressed files and facilitate management and operation.
