A detailed explanation of the relative path of the TAR packet compression

Now there is a need, do not know how to achieve

Compression: Tar czvf/data/backup/test.tar.gz/data/a/b/directory

Decompression: Cd/data/test

Tar xzvf/data/backup/test.tar.gz

The problem is, the unpacked file, inside the/data/test/data/a/b/directory

Can you compress only all directories below your directory, with directory as/, rather than/data/a/b/directory?

The issue has been resolved and the official information on GNU tar has been found.

Http://www.delorie.com/gnu/docs/tar/tar_98.html

That's going to work out.

Tar czvf/data/backup/test.tar.gz/data/a/b/directory

Change into

Tar czvf/data/backup/test.tar.gz-c/data/a/b Directory

C is a temporary switch to the working directory,-P is the absolute path, where only the-c parameter is used.
