| May 8, 2020 at 22:50 | comment | added | josch | @Mr.Roland The docs are correct. I just read them wrongly. The only thing saving my dignity is the comment on top of the "blocking" chapter: "Block and record terminology is rather confused, and it is also confusing to the expert reader." As a result I updated my answer with what I learned. | |

explain why an empty tarball is 10240 zero bytes

| May 7, 2020 at 6:25 | comment | added | Mr. Roland | Maybe the doc is incorrect. | |
| May 6, 2020 at 18:02 | comment | added | josch | @Mr.Roland then it seems we need to file a bug report against GNU tar because then the "empty tar" it outputs is faulty. | |

" two 512 blocks" if each block is 20 bytes this would be 2*512*20 which equals 20480

Or as empirical evidence: tar --create --files-from /dev/null | wc -c will give a file with 10240 zeros.

| Apr 24, 2020 at 10:51 | comment | added | Mr. Roland | "just a file with 10240 NUL bytes in it" source for that? | |

| Jan 15, 2019 at 6:58 | comment | added | josch | @KamilMaciorowski thanks for your hints about dd usage! I learned something new! About answering the right question: The title indeed asks "how to force tar" but when reading the question text, it becomes clear, that OP actually wants an empty tar file and it should not matter how. | |
