it appeared +in +.St -p1003.1-96 +but was dropped from +.St -p1003.1-2001 . +.Pp +The cpio, ustar, and pax interchange file formats are defined by +.St -p1003.1-2001 +for the pax command. +.Sh HISTORY +The original +.Nm cpio +and +.Nm find +utilities were written by Dick Haight +while working in AT&T's Unix Support Group. +They first appeared in 1977 in PWB/UNIX 1.0, the +.Dq Programmer's Work Bench +system developed for use within AT&T. +They were first released outside of AT&T as part of System III Unix in 1981. +As a result, +.Nm cpio +actually predates +.Nm tar , +even though it was not well-known outside of AT&T until some time later. +.Pp +This is a complete re-implementation based on the +.Xr libarchive 3 +library. +.Sh BUGS +The cpio archive format has several basic limitations: +It does not store user and group names, only numbers. +As a result, it cannot be reliably used to transfer +files between systems with dissimilar user and group numbering. +Older cpio formats limit the user and group numbers to +16 or 18 bits, which is insufficient for modern systems. +The cpio archive formats cannot support files over 4 gigabytes, +except for the +.Dq odc +variant, which can support files up to 8 gigabytes. |
