Introduction to Pax

pax is an archiving utility created by POSIX and defined by the POSIX.1-2001 standard. Rather than sort out the incompatible options that have crept up between tar and cpio, along with their implementations across various versions of UNIX, the IEEE designed a new archive utility. The name pax is an acronym for portable archive exchange. Furthermore, pax means peace in Latin, so its name implies that it shall create peace between the tar and cpio format supporters. The command invocation and command structure is somewhat a unification of both tar and cpio.

pax has been required to be present in LSB conformant systems since LSB version 3.0.

This package is known to build and work properly using an LFS 12.1 platform.
