hi all
i cannot extract any bz2 files cuz whenever i use tar vxjf filename or tar vxf filename it says invalid j option or invalid tar magic if i omit the j option .

any clues how to unpack that thing ?

thanks

No thats unpacking gzipped archives (.tar.gz)

N900' tar indeed doesnt have bzip2 compiled in.. However there is the bunzip2 available which you can use to unpack it to a .tar:

Code:

bunzip2 filename.tar.bz2
tar -xvf filename.tar

That's for tar.gz

Install tar-gnu and use gtar instead of tar.
The BusyBox tar is crippled (as are all other busybox tools)

I usually just do it in 2 steps.

unzip it first then untar the file.

Or do it in one step without an intermediate file:

Code:

bunzip2 -dc foobar.bz2 | tar x

tar xvf file.bz2
