ODOC: bzip2

bzip2 — A Block-sorting file (de)compressor.


bzip2 compresses files using the Burrows-Wheeler block sorting text compression algorithm, and Huffman coding. Compression is generally considerably better than the conventional compressors, & approaches the performance of the PPM family of statistical compressors.


$ bzip2 myfile — Compress & Save it in myfile.bz2. Delete the input file.

$ bzip2 -k myfile — Same as above. But Don’t delete the input file.

$ bzip2 -d myfile.bz2 — Decompress & Save it in myfile. Delete the input file.

$ bzip2 -kd myfile.bz2 — Same as above. But don’t delete the input file.

$ bzip2 -fd myfile.bz2 — Force overwrite of output files (by default not overwrite existing files).

$ bzip2 -t myfile.bz2 — Check the integrity of the compressed file.

$ bzip2 -v myfile — Show the detail status info about the operation.

$ bzip2 -q myfile — Suppress non-essential warning messages.

$ tar -cjvf myfile.tar.bz2 mydir — BZip2 thru TAR command.

$ tar -xjvf myfile.tar.bz2 — BUnZip2 thru TAR command.
