Let me try to give some information on star
star by default writes to stdout and already supports 7z compression
including auto-format/comression detection. You need to install a working
"p7zip" in your PATH.
Star is 100% compatible to tar, a big problem is that GNU tar is not 100%
compatible to tar.
Star is not only a TAR archiver but a complete solution.
- Star is an archiver library supports the most important archive
formats:
- OLD UNIXv7 tar
- OLD BSD tar
- POSIX-1.1988 TAR
- POSIX-1.2001 TAR
- CPIO
- the old star format from 1985 (the first tar with special
file support)
- Star extensions on POSIX-1.1988 TAR
- Star extensions on POSIX-1.2001 TAR - this include _working_
incremental dump/restore
- Star's upper layer supports several CLI variants depending on av[0]:
- Star - the UNIX compatible CLI that star introduced in 1982
under the name "star", all features of all archiveers are
available.
- TAR - the SUSv2 (UNIX-98) TAR CLI
- gtar - all useful features of GNU tar 1.14
- pax - the POSIX archiver
- cpio - the SUSv2 (UNIX-98) cpio CLI
- Star has a built in find(1) that works in archive/extract/list/copy
mode. It helps to make star very powerful as this find includes
-chown/-chgrp/-ghmod to on-the-fly change incore information during
archive processing.
- Star implements highly optimized buffering for optimum I/O thoughput
- Star typically needs 1/3 of the user CPU time than GNU tar
- Star supports fully correct archiving of sparse files if the OS
supports to read the hole list.
- Star supports ACLs in an OS independent way.
- Star supports Linux specific features (like file flags and XATTR).
GNU tar does not implement a single Linux specific feature.
- Star implementes ~ 2x as many features as GNU tar does.
- The star archive format extensions are fully documented.
For more information see http://cdrecord.berlios.de/old/private/star.html
The main problem on many Linux distributions is that they do not actively
maintain recent star packages.
If you believe that star called as "tar" does not behave correctly (as decribed
in http://www.opengroup.org/onlinepubs/007908799/xcu/tar.html, send me a report!
