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.
