How to view details of compressed files in Linux?

In Linux systems, you can usually use some common commands and tools to display compressed file information. Several commonly used methods will be introduced below and specific code examples will be given.

1. Use the "file" command

You can use the "file" command to view the type of file, including compressed files. For example, to check whether a file is a compressed file, you can use the following command:

file example.zip

This will show that the file type is a ZIP compressed file.

2. Use the "zcat", "zless", and "zmore" commands

For the content in the compressed file, you can use the "zcat" command to display its content. The sample code is as follows:

zcat example.gz

This will display the contents of the compressed file example.gz.

3. Use the "zgrep" command

Sometimes we may need to search for a certain string in a compressed file. You can use the "zgrep" command at this time. The sample code is as follows:

zgrep "search term" example.gz

This way you can search for lines containing "search term" in the example.gz file.

4. Use the "unzip" command

If it is a compressed file in ZIP format, you can use the "unzip" command to decompress it and view its contents. The sample code is as follows:

unzip example.zip

This will decompress the example.zip file to the current directory and display its contents.

5. Use the "tar" command

For compressed files in tar format, you can use the "tar" command to view their contents. The sample code is as follows:

tar -tzf example.tar.gz

This will list all file names in example.tar.gz.

In general, there are many ways to display compressed file information in Linux systems, and the above are some of the common methods. According to different compressed file formats, it is very convenient to select the corresponding command to view file information.
