szip, sunzip: (c) 1997 Michael Schindler, michael@eiunix.tuwien.ac.at http://eiunix.tuwien.ac.at/~michael/szip The programs szip and sunzip perform data compression/decompression. Both are version 1.03a, and there is no guarantee that this file format will be supported in later versions. I know several places where to improve speed and compression; this will be done as time allows. Usage: szip [inputfile [outputfile]] sunzip [inputfile [outputfile]] if outputfile is omitted output is written to standardoutput. if inputfile is omitted too input is read from standardinput. Operating systems supported: DOS, 16-bit windows: szip_xxx.zip (you may or may not need the included DPMI server by C.W.Sandman) Windows 32bit: szip_xxx_win32.zip LINUX elf: szip_xxx_linux.tgz KNOWN BUGS: I had no problems compressing and decompressing 6000 files. CAVEATS: DOS/Windows does NOT support binary pipes, so SPECIFY BOTH FILES. Due to the huge blocking (2MB blocks) tape backup operation is not as smooth as it could be (tapedrive stops often). This will be fixed. The next release WILL have a new binary output, this one will no longer be supported, but this Version will stay available at the website. If there is interest I will also compile them for other operating systems. The code is portable ANSI C, and the output file is portable too. These Programs can be freely distributed as unchanged executeables, as long as this file accompanies them unchanged and no charge that exceeds the copying cost is collected. The intention is only demonstration; I do not consider them production versions. These free programs come with ABSOLUTELY NO WARRANTY OF ANY KIND. Ask me about compression for your data; I will take a look at it like I did for CERN's ALICE project (2.5 GByte/sec) and KLOE (50MByte/sec). Both projects are high energy physics and standard compression will not work. So if you have high data volumes (oil prospecting, measurement data, anything else) that need to be stored or transmitted let me see what I can do.
