Let me try to give some information on star |
| 2 |
|
| 3 |
star by default writes to stdout and already supports 7z compression |
| 4 |
including auto-format/comression detection. You need to install a working |
| 5 |
"p7zip" in your PATH. |
| 6 |
|
| 7 |
Star is 100% compatible to tar, a big problem is that GNU tar is not 100% |
| 8 |
compatible to tar. |
| 9 |
|
| 10 |
Star is not only a TAR archiver but a complete solution. |
| 11 |
|
| 12 |
- Star is an archiver library supports the most important archive |
| 13 |
formats: |
| 14 |
|
| 15 |
- OLD UNIXv7 tar |
| 16 |
- OLD BSD tar |
| 17 |
- POSIX-1.1988 TAR |
| 18 |
- POSIX-1.2001 TAR |
| 19 |
- CPIO |
| 20 |
- the old star format from 1985 (the first tar with special |
| 21 |
file support) |
| 22 |
- Star extensions on POSIX-1.1988 TAR |
| 23 |
- Star extensions on POSIX-1.2001 TAR - this include _working_ |
| 24 |
incremental dump/restore |
| 25 |
|
| 26 |
- Star's upper layer supports several CLI variants depending on av[0]: |
| 27 |
|
| 28 |
- Star - the UNIX compatible CLI that star introduced in 1982 |
| 29 |
under the name "star", all features of all archiveers are |
| 30 |
available. |
| 31 |
- TAR - the SUSv2 (UNIX-98) TAR CLI |
| 32 |
- gtar - all useful features of GNU tar 1.14 |
| 33 |
- pax - the POSIX archiver |
| 34 |
- cpio - the SUSv2 (UNIX-98) cpio CLI |
| 35 |
|
| 36 |
- Star has a built in find(1) that works in archive/extract/list/copy |
| 37 |
mode. It helps to make star very powerful as this find includes |
| 38 |
-chown/-chgrp/-ghmod to on-the-fly change incore information during |
| 39 |
archive processing. |
| 40 |
|
| 41 |
- Star implements highly optimized buffering for optimum I/O thoughput |
| 42 |
|
| 43 |
- Star typically needs 1/3 of the user CPU time than GNU tar |
| 44 |
|
| 45 |
- Star supports fully correct archiving of sparse files if the OS |
| 46 |
supports to read the hole list. |
| 47 |
|
| 48 |
- Star supports ACLs in an OS independent way. |
| 49 |
|
| 50 |
- Star supports Linux specific features (like file flags and XATTR). |
| 51 |
GNU tar does not implement a single Linux specific feature. |
| 52 |
|
| 53 |
- Star implementes ~ 2x as many features as GNU tar does. |
| 54 |
|
| 55 |
- The star archive format extensions are fully documented. |
| 56 |

|
| 59 |
The main problem on many Linux distributions is that they do not actively |
| 60 |
maintain recent star packages. |
| 61 |
|
| 62 |
If you believe that star called as "tar" does not behave correctly (as decribed |
| 63 |
in http://www.opengroup.org/onlinepubs/007908799/xcu/tar.html, send me a report! |
