Learn how to view compressed file information in Linux

In Linux systems, compressed files are a file type we often encounter. Compressed files are often used to reduce the size of files to save storage space or to make transferring files more convenient. Knowing how to view compressed file information is very useful for operating system management and maintenance. This article will introduce how to view compressed file information in Linux systems, and provide specific code examples to help readers learn better.

In Linux systems, there are many common compressed file formats, such as .zip, .tar, .gz, .bz2, etc. For different compression formats, we can use different commands to view compressed file information.

1. View .zip file information

For .zip files, we can use the unzip command to view compressed file information, including the file list contained in the compressed file, compression Ratio, compression method, etc. The following is an example:

unzip -l file.zip

The above command will list all file information contained in the file.zip compressed file.

2. View .tar file information

For .tar files, we can use the tar command to view compressed file information. Here is an example:

tar -tvf file.tar

The above command will list the details of all files contained in the file.tar compressed file, including file name, size, permissions, etc.

3. View .gz file information

For .gz files, we can use the zcat command to view the contents of the compressed file, and the gzip command to view the compressed file information . The following is an example:

gzip -l file.gz

The above command will display the detailed information of the file.gz compressed file, including compression ratio, size before and after compression, etc.

4. View .bz2 file information

For .bz2 files, we can use the bzcat command to view the contents of the compressed file, and the bzip2 command to view the compressed file information . The following is an example:

bzip2 -l file.bz2

The above command will display the detailed information of the file.bz2 compressed file, including compression ratio, size before and after compression, etc.

Through the above examples, we can clearly understand how to view information about compressed files in different formats in Linux systems. Proficiency in these commands can help us better manage and maintain the file system and improve work efficiency. We hope that readers can gain a deeper understanding of compressed file-related operations in Linux systems through the introduction and sample code of this article.
