Linux gunzip Command

Linux Command Manual

The Linux gunzip command is used to decompress files.

gunzip is a widely used decompression program that is used to unpack files compressed with gzip, which typically have the .gz extension. In fact, gunzip is a hard link to gzip, so both compression and decompression can be accomplished with the gzip command alone.

Syntax

Parameters:

gunzip [-acfhlLnNqrtvV][-s &lt;compressed suffix string>][files...] or gunzip [-acfhlLnNqrtvV][-s &lt;compressed suffix string>][directory]

-a or --ascii: Use ASCII text mode.
-c or --stdout or --to-stdout: Output the decompressed file to the standard output device.
-f or --force: Forcefully decompress the file, ignoring whether the file name or hard link exists and whether the file is a symbolic link.
-h or --help: Display online help.
-k or --keep: Keep the original compressed file.
-l or --list: List information about the compressed file.
-L or --license: Display version and copyright information.
-n or --no-name: When decompressing, ignore the original file name and timestamp if they are contained within the compressed file.
-N or --name: When decompressing, restore the original file name and timestamp if they are contained within the compressed file.
-q or --quiet: Do not display warning messages.
-r or --recursive: Recursively process all files and subdirectories in the specified directory.
-S<compressed suffix string> or --suffix<compressed suffix string>: Change the compressed suffix string.
-t or --test: Test the integrity of the compressed file.
-v or --verbose: Display the execution process of the command.
