This is the Nov87 release of a public domain tar(1) replacement. It implements the 'c', 'x', and 't' commands of Unix tar, and many of the options. It creates P1003 "Unix Standard" [draft 6] tapes by default, and can read and write both old and new formats. It can compress or decompress tar archives "on the fly" (using the 'z' option) as well as accessing remote tape drives or files by specifying "host:/dev/tapedrive". It lets you set the default tape drive by setting TAPE in your environment. Its verbose output looks more like "ls -l" than the Unix tar, the columns line up, and you can get verbose listings from the 'cvv' option as well as from 'xvv' and 'tv'. It does shell-globbing (regular expressions) for listing and extraction. It is a little better at reading damaged tapes than Unix tar. There is a half-baked "diff" option for comparing a tape against the file system. And it's free. It is designed to be a lot more efficient than the standard Unix tar; it does as little bcopy-ing as possible, and does file I/O in large blocks. On the other hand, it has not been timed or performance-tuned; it's just *designed* to be faster. On SunOS 3.3, the tar archives it creates under the 'old' option are byte-for-byte the same as those created by /bin/tar, except the trash at the end of each file and at the end of the archive has been replaced by zeroes. It was written and initially debugged on a Sun Workstation running 4.2BSD. It has been run on Xenix, Unisoft, Vax 4.2BSD, utzoonix, USG, Masscomp, Minix, and MSDOS systems. I'm interested in finding people who will port it to other types of (Unix and non-Unix) systems, use it, and send back the changes; and people who will add the obscure tar options that they happen to use and I don't. In particular, VMS, Mac, Atari and Amiga versions would be handy. It still has a number of loose ends, marked by "FIXME" comments in the source. Fixes to these things are also welcome. I am the author of all the code in this program, except some of the subroutines, which are from contributors listed below. I hereby place it in the public domain. If you modify it, or port it to another system, please send me back a copy, so I can keep a master source. This program is much better than it started, due to the effort and care put in by Henry Spencer, Fred Fish, Ian Darwin, Geoff Collyer, Stan Barber, Guy Harris, Dave Brower, Richard Todd, Michael Rendell, Stu Heiss, and Rich $alz. Thank you, one and all.
