1. Grammar

Gunzip [- acfhlLnNrtvV] [- S suffix] file

2. List of options

Option

Description

-h |-- help

Help information

-V |-- version

Display command version information

-f |-- force

Enforcement

-a |-- ascii

Text mode. This option is only supported on some non-Unix systems.

-c |-- stdout |-- to-stdout

Write the extracted file to standard output, and the source file remains unchanged. If there are multiple input files, the output consists of a series of independently compressed members. For better compression, connect all input files before compressing them.

-l |-- list

List information about compressed files

-L |-- licence

List the license for gzip and exit

-n |-- no-name

When unzipping, do not restore the original file name (only remove the gzip suffix from the compressed file name) if it exists, and do not restore the original timestamp (copy it from the compressed file) if it exists. This option is the default when unzipping.

-N |-- name

When unzipping, if present, restore the original file name and timestamp. This option is useful for systems that limit the length of file names or for systems that lose timestamps after file transfer.

-r |-- recursive

Recursively traverse the directory structure.

-t |-- test

Test the integrity of the compressed file

-v |-- verbose

Show detailed execution process

-S

When unzipping, when deriving the output file name from the input file name, add .suf to the beginning of the suffix list with an attempt.

3. Examples

1) decompression

[root@localhost weijie] # gunzip-v 1.gz / / decompress to show the detailed execution process

1.gz: 9.4%-replaced with 1

2) specify the file suffix

[root@localhost weijie] # gunzip-v 1.mygz / / decompress. The suffix is not gz. An error was reported.

Gzip: 1.mygz: unknown suffix-- ignored

[root@localhost weijie] # gunzip-v-S "mygz" 1.mygz / / specifies a suffix without error reporting

1.mygz: 9.4%-- replaced with 1.
