Note:sex just calls the relevant program, itself does not have compression, decompression function .

So many tools, if we are compressed files, which tool to use, the following is a very useful in the Linux platform for a decompression tool.

gzip command

There are two obvious benefits of reducing file size, one is to reduce storage space, and the other is to reduce transmission time when transferring files over the network. Gzip is a frequently used Linux system command to compress and decompress files, which is both convenient and useful.

语法：gzip[选项] 压缩（解压缩）的文件名

The options for this command have the following meanings:

• -C writes the output to the standard output and retains the original file.

• -D Unzip the compressed file.

• -L Displays the following fields for each compressed file: The size of the compressed file, the size of the uncompressed file, the compression ratio, the name of the uncompressed file

• -R recursively finds the specified directory and compresses all of its files or is decompressed.

• -T test to check that the compressed file is complete.

• -V for each compression and decompression file, display the filename and compression ratio.

• -num adjusts the speed of compression with the specified number num,

• -1 or –fast represents the fastest compression method (low compression ratio),

• -9 or –best represents the slowest compression method (high compression ratio). The system default value is 6.

Example

.gz 文件。gzip -dv *% 把当前目录下每个压缩的文件解压，并列出详细的信息。gzip -l *% 详细显示例1中每个压缩的文件的信息，并不解压。gzip usr.tar% 压缩 tar 备份文件 usr.tar，此时压缩文件的扩展名为.tar.gz。
