I am writing a script wherein I need to merge files into existing
tar.gz
files. Currently, I am using tarfile module. I extract the tar.gz to a
tempdir and copy the new file there and re-compress all the files back
into
a tar.gz. Is there a better way to do it?
Since noone answered yet: no, I don't think you can avoid to decompress
and recompress those files.
Erm, I always thought it was OK to simply cat gzipped files together...
Maybe, but still I don't think this could help the OP. As I understand the
problem, originally there were e.g.: file1, file2, file3; they were tarred
into file123.tar and gzipped into file123.tar.gz. And now file2 must be
replaced by a newer version. It should go into the internal .tar file,
replacing the old one; I don't see how to do that without decompressing
it. (Ok, once the tar is decompressed one might replace the old file with
the newer one in-place using the tar command, but this cannot be done with
the tarfile Python module)
