add another file to tarred bzip2 file

[Ratzie]

I have a tarred bzip2 file that I made with gnu tar
gtar -jcvf sometar.bz2 /somedir

How do I add additional files to the tarred bzip2 file?

[Paul Cross_1 · Accepted solution]

bunzip the file, tar -r or tar -A to append the new file to the archive then re bzip the file.

example:
# bunzip2 archive.tar.bz2
# tar rf archive.tar newfile
# bzip2 archive.tar

you can do this in one step with tar rjf file.
