LZ4 is a data compression algorithm known for its high performance and efficiency. It is designed for rapid compression and decompression, making it an attractive choice for various scenarios, including data storage, network data transfer, and more.
Installing LZ4:
To install the LZ4 utility on Ubuntu, you can use the following command:
sudo apt-get install lz4
Basic Configuration Settings:
LZ4 provides several compression levels that can be configured based on your needs. Typically, compression levels are specified as numbers ranging from 1 to 9, where 1 is the fastest but less efficient in compression, and 9 is the highest compression level with longer execution times. You can specify the compression level when using the utility.
Basic Commands and Descriptions:
- Compressing a File:
lz4 -9 filename
This command compresses the filename file using the maximum compression level (9). The result will be saved in a file named filename.lz4.
- Decompressing a File:
lz4 -d filename.lz4
The command decompresses the filename.lz4 file and creates an uncompressed file named filename in the same directory.
- Compressing with a Specific Level:
lz4 -3 filename
In this example, compression level 3 is used. You can replace the number from 1 to 9 based on your performance and compression efficiency requirements.
- Displaying File Information:
lz4 -l filename.lz4
This command displays information about the file, such as the size of the original and compressed files, compression ratio, and other parameters.
LZ4 is a powerful and efficient tool for data compression in various scenarios. The choice of compression level depends on your specific performance and compression efficiency needs, and you can customize it according to your preferences.
