Fast Data Decompression：LZ4 on Linux（lz4解压linux）

With the rapid development of the Internet industry, massive data generated by the Internet is looming, and the size of data is growing day by day. In order to use the data more efficiently, the problem of data compression has been widely concerned.

Data compression is a special computer technology that can reduce the size of a data set and reduce the capacity of system storage, transmission and transmission of data. Data decompression is the process of making compressed data readable and restoring compressed data back to its previous state. With the development of technology, the speed, accuracy, security and quality of the data decompression process have become increasingly high.

LZ4 is an ultra-fast general-purpose compression algorithm, developed by Yann Collet, which provides a certain balance in the speed of compression and decompression while still providing surety. LZ4 also has lower memory requirements, higher correctness, and better portability than other similar algorithms.

It was originally intended as a replacement for the LZO algorithm for low-resource devices, but has been adopted by a wider range of products. Especially for Linux users, the LZ4 algorithm is quite suitable for data decompression. The LZ4 algorithm has strong support for Linux operating system, making it a good choice for Linux users who need to decompress data quickly.

Let’s take a look at an example to understand how to perform fast data decompression with LZ4 on Linux. We can begin by installing the lz4 command line tool and compressing a file, as follows:

`sudo apt-get install lz4`

`lz4 datafile.txt datafile.txt.lz4`

To decompress the file, you can use the lz4command with the -d flag, as follows:

`lz4 -d datafile.txt.lz4 datafile_decompressed.txt`

The above commands should be sufficient to quickly decompress data on Linux using the fast and reliable LZ4 algorithm.

In conclusion, the LZ4 algorithm can provide users with safe and efficient data decompression service on Linux platforms, making it highly suitable for data compression and decompression tasks. Therefore, it is recommended for Linux users needing fast data decompression to use the LZ4 algorithm, either manually with the command line tools or through library binaries.
