@Yuval seek is an ability of the tar program to be used with archive formats that support random access, the tar archive format itself isn't designed for random access. ( en.wikipedia.org/wiki/Tar_%28computing%29#Random_access ) ( duplicity.nongnu.org/new_format.html#nottar ) It is possible to extract individual files from a tar, but this requires scanning the whole archive first to find them because there is no central catelogue.

P.S. thanks for the lengthy explanation. zip is an excellent option for what I am looking for, and I might use it. Regarding extracting a single file for a gzip-compressed tar archive, the command would be: tar xfz archive.tgz path/in/archive/to/file

Thanks for you answer. However, I did not read beyond the two first paragraphs of your answer, for two reason. First, you didn't understand my question correctly: I asked whether tar has an ability to compress the files while adding them to the archive. Second, you wrote incorrectly that tar doesn't support random access: see the --seek option.
