Preface
1. In the previous section, we talked about the first compression format zip available under Linux. If you haven’t read it yet, click the link below to enter: zip
2. In this section we talk about the second compressed package format gz
Tip: The following is the content of this article
One, gzip command
The gzip command can compress files into a compressed package in gz format.
- Command name: gzip
- The full name of the command: gunzip, zcat-compress or expand files
- Location: /usr/bin/gzip
- Execution authority: all users
- Function description: compressed files
命令格式
gzip [选项] 要压缩的文件
常用选项：
-c：压缩后保留源文件（一般不加-c压缩完后会删除源文件，只保留压缩后的文件）
-d：解压缩
-r：压缩目录文件
Example:
压缩：
[root@VM-0-12-centos snlyj]# ls
ll.txt loli.txt
[root@VM-0-12-centos snlyj]#
[root@VM-0-12-centos snlyj]# gzip loli.txt
[root@VM-0-12-centos snlyj]#
[root@VM-0-12-centos snlyj]# ls
ll.txt loli.txt.gz
[root@VM-0-12-centos snlyj]#
（直接gzip后面接文件，系统会自动将文件压缩成.gz后缀的压缩包，并删除源文件。）
（压缩目录加-r选项即可，不想删除源文件加-c选项即可。）
Decompression example:
[root@VM-0-12-centos snlyj]# ls
ll.txt loli.txt.gz
[root@VM-0-12-centos snlyj]#
[root@VM-0-12-centos snlyj]# gzip -d loli.txt.gz
[root@VM-0-12-centos snlyj]#
[root@VM-0-12-centos snlyj]# ls
ll.txt loli.txt
[root@VM-0-12-centos snlyj]#
（直接加-d选项后面接要解压缩的.gz格式的压缩包即可解压缩）
Two, gunzip command
gzip -d xx can be used to decompress compressed packages in gz format. The gunzip command is the same as the -d option and can also be used to decompress compressed packages in gz format.
- Command name: gunzip
- Location: /usr/bin/gunzip
- Execution authority: all users
- Function description: decompress files
命令格式：
gunzip 要解压缩的文件
Example:
[root@VM-0-12-centos snlyj]# ls
ll.txt loli.txt.gz
[root@VM-0-12-centos snlyj]#
[root@VM-0-12-centos snlyj]# gunzip loli.txt.gz
[root@VM-0-12-centos snlyj]#
[root@VM-0-12-centos snlyj]# ls
ll.txt loli.txt
[root@VM-0-12-centos snlyj]#
（直接gunzip 后面接要解压缩的文件即可解压缩文件）
to sum up
In this section we learned
{
gzip: The compressed file is a gz format compressed package
gunzip: decompress the compressed package in gz format (gzip -d can also decompress the compressed package in gz format when you connect to the file to be decompressed, depending on which one you use)
}
This is Jiehua, see you next time!
