As powerful as tar(1) is …
Readin thetar(1)
man page (because you, as I do, sometimes re-read man pages, right?) I found that the BSD version, in particular the FreeBSD version, of tar(1)
does support a lot more file layouts.
GNU
tar(1)
supports the following compressed formats:
bzip2(1)
xz(1)
lzip(1)
lzma(1)
lzop(1)
while the FreeBSD version supports also:zstd
lrzip(1)
lz4
but here is more than just compression. BSDtar(1)
also provides native support foriso9660
(disk images) and encryption!
Sincetar(1)
is shipped with the base system, seems FreeBSD has access to a lot more archive formats than regular GNU distributions.
