Official documentation still calls out that fish is not the default shell and that some behavior differs from bash-like shells, which is central to its identity. The current upstream repository was created on GitHub in 2012, while the release notes preserve a longer line of 2.x, 3.x, and 4.x releases. Version 3.0.0 arrived in December 2018, 3.7.0 in January 2024, and 4.0.0 in February 2025, after a beta in December 2024. ### Adoption history fish is widely packaged across Unix-like systems. The upstream README documents Homebrew, MacPorts, official installers, Linux packages through openSUSE Build Service and Ubuntu PPAs, WSL, Cygwin, and MSYS2; the Homebrew input also records packages for apk, Debian, Fedora, Nix, pacman, Ubuntu, and zypper. ### How it is used Users commonly install fish alongside their system shell, run `fish` from an existing shell to try it, then make it their login shell if the syntax and interactive model fit. Configuration centers on `config.fish`, functions, completions, universal variables, and prompt/theme customization. ### Why package nerds care fish matters in package-manager culture because it is both an application and a shell integration target. Packages often ship fish completions, prompts and plugin managers target its function/completion layout, and distributors track changes such as fish 4.x moving more implementation and packaging work into Rust/Cargo-era build requirements. ### Timeline - 2012: Current GitHub repository created. - 2018: fish 3.0.0 released. - 2024: fish 3.7.0 released. - 2025: fish 4.0.0 released. - 2026: fish 4.8.0 released. ### Related projects - Related projects include bash, zsh, POSIX sh, shell completion packages, prompt frameworks, fish-lsp, and editor integrations for fish scripts. ### Sources - - - - - ## Security Notes generalized runtime or code generation signal. - **Geiger risk:** yellow / medium - generalized runtime or code generation signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
