Question

I have a problem with checking uncompressed size from archive tar.xz without extract whole archive. I know that for tar.gz I can use gzip or zcat but for tar.xz it dosnt work.

Any sugestion how to do this ?

Answer 1

tar tvfa <file> will give you a list including file sizes. Check man tar for details. You should also note, that file size does not equate to disk usage, since part of a file can take a full file system block.
