> Is "bz2" some new compressed format? If so, how do I uncompress it? Yes. It's the Burrows - Wheeler algorithm and belongs into the realm of block compression methods. Basically it separates the input data into blocks and reorders the bit sequences until redundancy is maximized and then compresses the resulting bit stream. It also stores all the reordering actions it did so that everything can be undone. Burrows and Wheeler succeeded in proving that this provides excellent compression. It, however, is computing intensive - compression takes 5 to ten times longer than with gzip. To exploit that new approach, there is the program "bzip2". It has been with Slackware since version 3.4. ================================================================ "It was hell. They knew it.
