Star is a full-featured tar command that can access local and remote tar archives (files and tapes). It reads and writes POSIX compliant tar archives as well as non-POSIX GNU tar archives. Star is the first POSIX.1-2001 compliant tar implementation. It includes a FIFO for speed, a pattern matcher, multi-volume support, the ability to archive sparse files and ACLs and the ability to archive extended file flags. It supports automatic archive format detection, automatic byte order recognition, automatic archivecompression/decompression. It includes the only known platform independent "rmt" server program that implements all Sun/GNU/Schily/BSD enhancements and allows any "rmt" client from any OS to contact any OS as server.
