This article mainly introduces the relevant knowledge of the use of Linux's bzip2 command, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this Linux bzip2 command. Let's take a look at it.

Linux commonly used command bzip2 command is the .bz2 file compression program, bzip2 uses a new compression algorithm, the compression effect is better than the traditional LZ77/LZ78 compression algorithm. If no parameters are added, bzip2 will produce a .bz2 compressed file after compressing the file and delete the original file.

Syntax bzip2 [- cdfhkLstvVz] [--repetitive-best] [--repetitive-fast] [- Compression level] [File to be compressed] parameters:

-c or-stdout sends the results of compression and decompression to standard output.

-d or-decompress performs decompression.

When-f or-force bzip2 compress or decompress, if the output file has the same name as the existing file, the default will not overwrite the existing file. To override, use this parameter.

-h or-help displays help.

-k or-keep bzip2 deletes the original file after it is compressed or unzipped. To keep the original file, use this parameter.

-s or-small reduces the amount of memory used when the program is executed.

-t or-test tests the integrity of the .bz2 compressed file.

Detailed information is displayed when-v or-verbose compresses or decompresses the file.

-z or-compress enforces compression.

-Lmam Murphy license

-V or-version displays version information.

-repetitive-best if there are repeated data in the file, you can use this parameter to improve the compression effect.

-repetitive-fast if there are repeated data in the file, you can use this parameter to speed up the execution.

-the block size at which the compression level is compressed.
