version][go-version-badge]\n\n**gb3sum** is a command-line utility for printing and checking [BLAKE3]\nchecksums.\n\ngb3sum is written in [Go] and compiles into a single binary with no external\ndependencies.\n\n## Installation\n\n### From source\n\n```sh\ngo install github.com/sorairolake/gb3sum@latest\n```\n\n### From binaries\n\nThe [release page] contains pre-built binaries for Linux, macOS, Windows and\nothers.\n\n### How to build\n\nPlease see [BUILD.adoc].\n\n## Usage\n\n### Basic usage\n\n#### Print BLAKE3 checksums\n\n```sh\necho \"Hello, world!\" \u003e foo.txt\ngb3sum foo.txt | tee b3sums.txt\n```\n\nOutput:\n\n```text\n94f1675bac4f8bc3c593c63dbf5fe78a0bfda01082af85d5b41a65096db56bff  foo.txt\n```\n\n#### Check BLAKE3 checksums\n\n```sh\ngb3sum -c b3sums.txt\n```\n\nOutput:\n\n```text\nfoo.txt: OK\n```\n\n### Generate shell completion\n\n`--generate-completion` option generates shell completions to standard output.\n\nThe following shells are supported:\n\n- `bash`\n- `fish`\n- `powershell`\n- `zsh`\n\nExample:\n\n```sh\ngb3sum --generate-completion bash \u003e gb3sum.bash\n```\n\n## Command-line options\n\nPlease see the following:\n\n- [`gb3sum(1)`]\n\n## Source code\n\nThe upstream repository is available at\n\u003chttps://github.com/sorairolake/gb3sum.git\u003e.\n\n## Changelog\n\nPlease see [CHANGELOG.adoc].\n\n## Contributing\n\nPlease see [CONTRIBUTING.adoc].\n\n## Comparisons\n\n`gb3sum` supports a command-line syntax similar but not identical to\ncoreutils's [`md5sum`].\n\n### Differences to coreutils's md5sum\n\n- `gb3sum` doesn't have options to specify the input mode (`-b` and `-t`).\n- `gb3sum` always treats files as binary file.\n- `gb3sum` doesn't have an option to terminate output lines with NUL (`-z`).\n- `gb3sum` has an option to specify the number of output bytes like coreutils's\n  [`b2sum`] (`-l`).\n\n### Differences to b3sum\n\nUnlike [`b3sum`], `gb3sum` doesn't support keyed hashing and key derivation.\nUse `b3sum` instead of `gb3sum` for those purposes.\n\n## License\n\nCopyright (C) 2024 Shun Sakai (see [AUTHORS.adoc])\n\n1.
