Interestingly, gzip came after zip (some 3 years later)
- billpg 3y agoI remember fruitlessly trying to open a .zip file with gunzip back in the mid 90s. That was my first experience of the GNU project.
- edu 3y agoWell, GZIP is GNU ZIP. I ale says expected it was developed after the original ZIP.
- 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.
- MitPitt 3y agoA gigazip is 1000 zips
- jjgreen 3y ago1024
- thecosmicfrog 3y agoThat would be a g̶i̶b̶i̶ kibizip.
- a1369209993 3y agoNo, it's a kilozip, like kilometer (= 1024 meters). A gigazip (not gibizip) would be 1'073'741'824 zips (1024^3 = 2^30). Also it should be Gzip, not gzip, although it's not ambiguous since the reciprocal prefix is nano-, and in general there are no 2^-X0 prefixes that start with g- like there is for Mega-/milli-.
