I made a bzip2 file by
bzip2 -c /home/os/picture1 > /home/os/Desktop/pic.image
bzip2 -c /home/os/picture2 >> /home/os/Desktop/pic.image
But now extracting pic.image by bzip2 -d /home/os/Desktop/pic.image returns
bzip2: Can't guess original name for pic.image -- using pic.image.out
and then it just creates one file pic.image.out.
How do I access picture1 and picture2 from pic.image?

bzip2 is compression only. If you want file packing then you need to use tar as well.

You should use tar instead :
tar cjf /path/to/pics.tar.bz2 /path/pic1 /path/pic2
tar xjf /path/to/pics.tar.bz2 -C /path/to/extract/

Okay got you. BUT my file's extension is not .tar.bz2. It's just .image. What do you suggest to get my picture1 and picture2 from pic.image? Got any hack in mind?? – Usman – 2011-01-12T15:54:43.107
hmm, all i can think of is writing a script that reads the file and extracts based on the bzip2 header, however there's no way of restoring the original file names that way. – OneOfOne – 2011-01-12T19:48:08.940
And from the documentation: If the file does not end in one of the recognised endings, .bz2, .bz, .tbz2 or .tbz, bzip2 complains that it cannot guess the name of the original file, and uses the original name with .out appended. – Arjan – 2010-12-13T14:02:38.237
so...now...there is no hack to access picture1 or picture2 from pic.image?? :-o – Usman – 2011-01-12T15:53:33.453
