The gunzip command in Linux can be used to decompress .gz compressed files. In fact, gunzip is a hard connection of gzip, so whether it is compression or decompression, it can be completed through the gzip command alone.

Linux gunzip command: decompress files or directories

gunzip is a widely used decompression command, which is used to decompress files compressed by gzip file (extension .gz).

To decompress files compressed by gzip, you can also use gzip itself, that is, gzip -d compressed package.

The basic format of the gunzip command is:

gunzip [options] file...

Parameters	Description
options	Parameters used by the gunzip command.
file	The name of the file to be decompressed.

Commonly used parameters of gunzip command

Parameter	Description
-a, --ascii	Use ASCII text mode.
-c, --stdout, --to-stdout	Output the decompressed file to the standard output device.
-f, --force	Forcibly decompress the compressed file, regardless of whether the file name or hard link exists and whether the file is a symbolic link.
-l, --list	List related information of compressed files.
-L, --license	Display version and copyright information.
-n, --no-name	When compressing a file, the original file name and timestamp will not be saved.
-N, --name	When compressing a file, save the original file name and timestamp.
-q, --quiet	Do not display warning messages.
-r, --recursive	Recursive processing, all files and subdirectories in the specified directory will be processed together.
-t, --test	Test whether the compressed file is correct.
-v, --verbose	Display the instruction execution process.

Example 1】Decompress the file directly.

[root@localhost ~]# gunzip install.log.gz

Of course, "gunzip -r" will still only decompress the files in the directory, but not unpack them. To decompress the ".gz" format, you can also use the "gzip -d" command, for example:

[root@localhost ~]# gzip -d anaconda-ks.cfg.gz

[Example 2] To decompress the contents of the directory, you need to use the "-r" option. For example:

[root@localhost ~]# gunzip -r test/

Note that if we are compressing a plain text file, you can directly use the zcat command to view the contents of the text file without decompressing it. For example:

[root@localhost ~]# zcat anaconda-ks.cfg.gz
