--best specifies the highest compression ratio;

-n specifies the compression ratio (n is a number and 1<=n<=9);

-v displays progress information;

bzip2/bunzip2 for compression/decompression

[syntax]

bzip2 file;

bunzip2 file ;

[Command Description]

bzip2 can usually generate files with higher compression ratio than gzip; default bzip2 will delete the source file, and use -k parameter to retain the source file;
