There's an issue The info-zip home page has a list of things unzip runs on, which effectively gives a very comprehensive list of OS types: http://www.info-zip.org/pub/infozip/UnZip.html the link to C-Kermit at the foot of the page reveals a large list of Unix variants: http://www.columbia.edu/kermit/unix.html [The zip file "spec" is on infozip's pages: http://www.info-zip.org/pub/infozip/doc/appnote-iz-latest.zip the gzip file format is rfc1952 <http://www.ietf.org/rfc/rfc1952.txt> the deflate compression method used by gzip is rfc1951 <http://www.ietf.org/rfc/rfc1951.txt> zip files can use a variety of compression methods - deflate is method 8. As best I can tell only deflate and storing uncompressed (method 0) are widely used nowadays. In theory there's nothing stopping you putting a bzip2 stream (or whatever arj or rar or any of the other archivers use) inside a zip archive if you standardise on the compression method number. Notice also the distinction - zip an archive format (put lots of files in one file and take them out again) which allows entries to be compressed. tar is just an archive format, gzip just a compression system. how very unix - combine small tools to get a job done :-) ] Nicholas ClarkThread Previous | Thread Next
