Commands for compressing bz2 files in CentOS

Bzip2 function description:. bz2 file compression program. Syntax: bzip2 [-cdfhkLstvVz] [-- repetitive-best] [-- repetitive-fast] [-compression grade] [file to be compressed] supplementary description: bzip2 adopts the new compression algorithm, which is better than the traditional LZ77/LZ78 compression algorithm. If no parameter is added, bzip2 will generate bzip2 after the file is compressed.

Function description:. bz2 file compression program.

Syntax: bzip2 [-cdfhkLstvVz] [-- repetitive-best] [-- repetitive-fast] [-compression grade] [file to be compressed]

Note: bzip2 adopts a new compression algorithm, which is better than the traditional LZ77/LZ78 compression algorithm. If no compression file is added, the compressed file .bz2 will be uploaded and the original file will be deleted.

Parameters:
-C or -- stdout sends the compression and decompression results to the standard output.
-D or -- decompress.
-F or -- force bzip2 will not overwrite the existing file if the output file has the same name as the existing file during compression or decompression. To overwrite data, use this parameter.
-H or -- help displays help.
-K or -- keep bzip2 will delete the original file after compression or decompression. To retain the original file, use this parameter.
-S or -- small reduces the memory usage during program execution.
-T or -- test the integrity of the. bz2 compressed file.
-V or -- verbose displays detailed information when compressing or extracting files.
-Z or -- compress enforces compression.
-L, -- license,
-V or -- version displays version information.
-- Repetitive-best: this parameter can be used to improve the compression effect if duplicate data appears in the file.
-- Repetitive-fast: this parameter can be used to speed up execution if duplicate data appears in the file.
-The block size when the compression level is compressed.
