- canucker2016 3y agogzip is just the compression/decompression algorithm (Deflate) from PKZip. They needed a new compress/decompress tool once IBM asserted their patent rights on the LZW algorithm used in the compress tool.
- account42 3y agogzip adds its own file header with lots of useless information like a field for a file name. zip uses a different header for the compression stream, commonly known as the zlib format. They also use different checksums at the end (CRC32 vs Adler32).
- sph 3y agoThat's what the name might mean but it's simply wrong. gzip is not the same format as ZIP, and the tool itself is unable to read or write ZIP files.
- account42 3y agoIt is however GNU's alternative to the zip format.
