| bsdtar | tar(1) from FreeBSD, using libarchive | Mehr ... |
The bsdtar program has a number of advantages over previous tar
implementations:
.
* Library. Since the core functionality is in a library, it can be
used by other tools, such as pkg_add.
.
* Automatic format detection. Libarchive automatically detects the
compression (none/gzip/bzip2) and format (old tar, ustar, gnutar,
pax, cpio, iso9660, zip) when reading archives. It does this for
any data source.
.
* Pax Interchange Format Support. This is a POSIX/SUSv3 extension to
the old "ustar" tar format that adds arbitrary extended attributes
to each entry. Does everything that GNU tar format does, only
better.
.
* Handles file flags, ACLs, arbitrary pathnames, etc. Pax interchange
format supports key/value attributes using an easily-extensible
technique. Arbitrary pathnames, group names, user names, file sizes
are part of the POSIX standard; libarchive extends this with
support for file flags, ACLs, and arbitrary device numbers.
.
* GNU tar support. Libarchive reads most GNU tar archives. If there
is demand, this can be improved further.

| libarchive-dev | Single library to read/write tar, cpio, pax, zip, iso9660, etc. | Mehr ... |
The libarchive library provides a flexible interface for reading and
writing streaming archive files such as tar and cpio. The library is
inherently stream-oriented; readers serially iterate through the archive,
writers serially add things to the archive. In particular, note that
there is no built-in support for random access nor for in-place
modification.
.
libarchive can read at least five tar formats, four cpio formats,
ISO9660 CD/DVD images (including RockRidge extensions), and ZIP
files.
.
libarchive can write two tar formats (ustar and pax), one cpio format
(odc/POSIX), and two types of shar files (with and without uuencoding).
.
The bsdtar Debian package, which is the default tar(1) on FreeBSD,
is built using libarchive.
.
There is also a manpage, tar(5), in libarchive1 that provides
an excellent description of the various tar file formats.
