Then I gzipped and renamed it to image.svgz. The resulted *.svgz file is supported by almost all browsers as a usual image. But now I would like to extract the original file back: $ gzip -d image.svgz gzip: image.svgz: unknown suffix -- ignored So gzip doesn't allow me to this just because the file have not a proper .gz extension. This makes sense because gzip can't determine the output file name. But gzip by default stores an original file name (-N or -name option) so let's add -N: $ gzip -l -N idea.svgz compressed uncompressed ratio uncompressed_name 849 2489 67.0% image.svg $ gzip -d -N image.svgz gzip: image.svgz: unknown suffix -- ignored Again the same problem while I clearly specified to use an original file name. I confused and from my point of view this is a bug. But if you try to decompress to stdout (i.e. use it with pipe and output to a file) then all will be find. The similar problem have another compressors like a new one ZStandard: https://github.com/facebook/zstd/issues/754 But in zstd there is an option to clearly specify the output file name: -o file: result stored into `file` (only if 1 input file) This also solves the problem but also makes it more convinced to call pragmatically gzip without pipes (i.e. to call it from an archive manager like GNOME File Roller) So, could you consider to implement the feature or will you accept a patch from me?
