Permission is granted to any individual or institution to use, copy, or redistribute this software so long as all of the original files are included unmodified, that it is not sold for profit, and that this copyright notice is retained. Zip 1.9 is a compression and file packaging utility. It is analogous to a combination of tar and compress and is compatible with PKZIP 1.93a (Phil Katz ZIP) for MSDOS systems. There is a companion to zip called unzip (of course) which you should be able to find the same place you got zip. (See the file 'where' for details on ftp sites and mail servers.) This version of zip has been ported to a wide array of Unix and other mainframes, minis, and micros including VMS, OS/2, Minix, MSDOS, Windows NT, Atari, and Macintosh (the latter two have not been tested recently). Although highly compatible with PKware's PKZIP and PKUNZIP utilities of MSDOS fame, our primary objective has been one of portability and other-than-MSDOS functionality. Features not found in the PKWare version include creation of zip files in a pipe or on a device, VMS and OS/2 extended file attributes, conversion from Unix to MSDOS text file format; and, of course, the ability to run on most of your favorite operating systems. And it's free. If you got this file from zip19.zip, you can extract the rest only with unzip 5.0 or pkzip 1.93a. See the file 'Where' if you do not have them already. Please read the file install.doc for information on how to compile and install zip, zipsplit and zipnote. Please read the file zip.doc for information on how to use them. The file "contents" is a complete list of the files you should have in this distribution. Also, if you are using MSDOS, you should read the note on file formats at the end of the contents file. This version supports encryption, but the encryption code is distributed separately because of the US export regulations. See the file 'Where' for access to the encryption code. Decryption can be made with unzip 5.0 or later, or with zipcloak (which is provided in the encryption supplement). All bug reports and patches should go to zip-bugs@cs.ucla.edu, and suggestions for new features can be sent to info-zip@cs.ucla.edu (although we don't promise to use all suggestions). Patches should be sent as context diffs only (diff -c). If you're considering a port, please check in with zip-bugs FIRST, since the code is constantly being updated behind the scenes. We'll arrange to give you access to the latest source. The alternative is the possibility that your hard work will be tucked away in a sub-archive and pretty much ignored. A port to VM/CMS would be welcome. If you'd like to keep up to date with our zip (and companion unzip utility) development, join the ranks of BETA testers, add your own thoughts and contributions, etc., send your request to Info-ZIP-Request@cs.ucla.edu and you will be added to the Info-ZIP newsletter mailing list. IMPORTANT NOTES: - pkzip 1.93a is only an alpha version (see historical notes below). If you wish to create zip files compatible with the official version of pkzip (1.10), you must use zip 1.0. zip 1.9 cannot create files with the old compression method (implosion). - zip 1.9 is is compatible with pkzip 1.93a, except when two features are used: encryption or zip file created in a pipe or on a non seekable device. pkzip versions of 2.0 will support such files, and unzip 5.0 already supports them. (Thanks to Phil Katz for accepting our suggested minor changes to the zip file format.) - the ports to the Macintosh and the Atari ST have been provided in the hope that they can be useful, but they have been adapted from an older version of zip (1.0) and are still completely untested. A makefile is still missing for the Mac. Another Macintosh port is being made by Johnny Lee but it requires more substantial changes so it will be distributed separately. - Please read the file zip.doc, and in particular its list of known bugs at the end. Historical notes: At the time of release of zip 1.9, the official released version of PKZIP is version 1.10. PKZIP 1.93a is only an alpha version, which was released in October 1991. It was supposed to be replaced soon after with an official release of pkzip 2.0. However, Phil Katz has not yet announced a release date at the time of writing (Aug 19th, 1992). Beta versions of zip compatible with pkzip 1.93a have been available since February 1992 to the info-zip group (see the file 'history'). The zip authors would have preferred to release zip 2.0 only after pkzip 2.0(*), to ensure full compatibility in case of archive format changes between pkzip 1.93a and 2.0. However we feel that we cannot delay any further the release of zip 1.9, since all the major features that we wanted to put in are now available and well tested by the info-zip group. (*) The version number for the new pkzip was planned to be 2.00, but may be increased to a number greater than 2.2 to prevent confusion with several bogus versions, which may destroy all the data on your hard disk if you run them.
