bzip2
Purpose
It is a block-sorting file compressor
USAGE
OPTIONS
Description
bzip2 compresses files using the Burrows-Wheeler block sorting text compression algorithm, and Huffman coding. Compression is generally considerably better than gzip.bzip2 expects a list of file names to accompany the command-line flags.
Each file is replaced by a compressed version of itself, with the name "original_name.bz2".
Each compressed file has the same modification date, permissions, and, when possible, ownership as the corresponding original, so that these properties can be correctly restored at decompression time.
The command-lineoptions are deliberately very similar to those of GNU gzip(gzip), but they are not identical.
Similarly to decompress bzip2 file, we can either pass -d as option or use bunzip.
