Synopsis

gnutar [options] [tarfile] [other-files]

Copies files to or restores files from an archive medium. An enhanced version of tar, gnutar is usually the preferred utility because gnutar can handle much longer pathnames than tar, and gnutar’s default omission of the leading slash in pathnames allows archives to be more easily opened on other systems. Note that until native drivers for tape drives exist for Mac OS X, gnutar can’t write to tape. Note also that gnutar doesn’t preserve resource forks or HFS metadata when copying files that contain them.

gnutar is installed on Mac OS X as part of Apple’s Xcode Tools.
