Extract Bz2

I know this is a silly question but:

I'm installing Jlime (new version) onto my 680. I'm using a Knoppix CD to sort of the CF card since we cant actually install Linux on school computers. The problem is how to extract a bz2 file (without using KDE, which is crippled in Knoppix).

opie.tar.bz2, when extracted places all contents into a folder called opie. Opening the file in windows you can see this folder is in the file.

How can extract this image without losing permissions and so on.

Never mind - bodged it

(For the record:

i mounted my cfcard as /mnt/opie, then extracted the archive from inside /mnt)

You definitely need to learn the tar command. tar -xjvpf filename.bz2

x means extract, j means bzip2, v means verbose (not required, but nice to know), p means preserve permissions, f means file.

Believe me, you don't want to rely on file-roller to do it for you graphically. It's vastly innefficient, and can cause hundreds of more r/w's than normal tar will do. (Why? Temporary file storage I guess, or just plain stupid design)

Whats file-roller?

I did use the tar command.

Rootshell, mount cfcard, go into /mnt, tar..., done

File-roller is a mess in my opinion, but it works. Until you start working with 4gb tar archives. Then everything goes downhill.

It copies the files into a temporary directory, even if the archive is not compressed. This makes adding files for the dvd backup a pain. The actual tar command decompresses very well, but I have not figured out how to add files without a gui.

Long story very short, it takes about an hour to open the archive, another to add files, no matter how small they are.

Ok, so it took an hour because I forgot to enable dma. *bonk*
