How do I convert a .bz2 archive of a single file into a .tar.bz2 archive? I can't decompress the entire thing and then recompress it, since the compression ratio is huge. I've tried every combination of "tar" "bunzip2" "|" ">" and "-" that I can think of, and it won't work.
Also, how do I determine the uncompressed size of a .bz2 file?
tar manual only describes how to read a compressed file from standard input and decompress it to a real file.
