For downloads, screenshots and more, go to https://fishshell.com/. Quick Start ----------- fish generally works like other shells, like bash or zsh. A few important differences can be found at https://fishshell.com/docs/current/tutorial.html by searching for the magic phrase “unlike other shells”. Detailed user documentation is available by running ``help`` within fish, and also at https://fishshell.com/docs/current/index.html Getting fish ------------ macOS ~~~~~ fish can be installed: - using `Homebrew `__: ``brew install fish`` - using `MacPorts `__: ``sudo port install fish`` - using the `installer from fishshell.com `__ - as a `standalone app from fishshell.com `__ Note: The minimum supported macOS version is 10.10 "Yosemite". Packages for Linux ~~~~~~~~~~~~~~~~~~ Packages for Debian, Fedora, openSUSE, and Red Hat Enterprise Linux/CentOS are available from the `openSUSE Build Service `__. Packages for Ubuntu are available from the `fish PPA `__, and can be installed using the following commands: :: sudo apt-add-repository ppa:fish-shell/release-3 sudo apt update sudo apt install fish Instructions for other distributions may be found at `fishshell.com `__. Windows ~~~~~~~ - On Windows 10/11, fish can be installed under the WSL Windows Subsystem for Linux with the instructions for the appropriate distribution listed above under “Packages for Linux”, or from source with the instructions below. - Fish can also be installed on all versions of Windows using `Cygwin `__ (from the **Shells** category). Building from source ~~~~~~~~~~~~~~~~~~~~ If packages are not available for your platform, GPG-signed tarballs are available from `fishshell.com `__ and `fish-shell on GitHub `__. See the `Building <#building>`__ section for instructions. Running fish ------------ Once installed, run ``fish`` from your current shell to try fish out! Dependencies ~~~~~~~~~~~~ Running fish requires: - A terminfo database, typically from curses or ncurses (preinstalled on most \*nix systems) - this needs to be the directory tree format, not the "hashed" database. If this is unavailable, fish uses an included xterm-256color definition. - some common \*nix system utilities (currently ``mktemp``), in addition to the basic POSIX utilities (``cat``, ``cut``, ``dirname``, ``file``, ``ls``, ``mkdir``, ``mkfifo``, ``rm``, ``sort``, ``tee``, ``tr``, ``uname`` and ``sed`` at least, but the full coreutils plus ``find`` and ``awk`` is preferred) - The gettext library, if compiled with translation support The following optional features also have specific requirements: - builtin commands that have the ``--help`` option or print usage messages require ``nroff`` or ``mandoc`` for display - automated completion generation from manual pages requires Python 3.5+ - the ``fish_config`` web configuration tool requires Python 3.5+ and a web browser - system clipboard integration (with the default Ctrl-V and Ctrl-X bindings) require either the ``xsel``, ``xclip``, ``wl-copy``/``wl-paste`` or ``pbcopy``/``pbpaste`` utilities - full completions for ``yarn`` and ``npm`` require the ``all-the-package-names`` NPM module - ``colorls`` is used, if installed, to add color when running ``ls`` on platforms that do not have color support (such as OpenBSD) Building -------- .. _dependencies-1: Dependencies ~~~~~~~~~~~~ Compiling fish from a tarball requires: - a C++11 compiler (g++ 4.8 or later, or clang 3.3 or later) - CMake (version 3.5 or later) - PCRE2 (headers and libraries) - optional, this will be downloaded if missing - gettext (headers and libraries) - optional, for translation support Sphinx is also optionally required to build the documentation from a cloned git repository. Additionally, running the test suite requires Python 3.5+ and the pexpect package. Dependencies, git master ~~~~~~~~~~~~~~~~~~~~~~~~ Building from git master currently requires: - Rust (version 1.70 or later) - CMake (version 3.19 or later) - PCRE2 (headers and libraries) - optional, this will be downloaded if missing - gettext (headers and libraries) - optional, for translation support - an Internet connection, as other dependencies will be downloaded automatically fish is in the process of being ported to Rust, replacing all C++ code. In general, we would currently not recommend running from git master if you just want to *use* fish. Given the nature of the port, what is currently there is mostly a slower and buggier version of the last C++-based release. Building from source (all platforms) - Makefile generator ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To install into ``/usr/local``, run: .. code:: bash mkdir build; cd build cmake .. make sudo make install The install directory can be changed using the ``-DCMAKE_INSTALL_PREFIX`` parameter for ``cmake``. Build options ~~~~~~~~~~~~~ In addition to the normal CMake build options (like ``CMAKE_INSTALL_PREFIX``), fish has some other options available to customize it. - BUILD_DOCS=ON|OFF - whether to build the documentation. This is automatically set to OFF when Sphinx isn't installed. - INSTALL_DOCS=ON|OFF - whether to install the docs. This is automatically set to on when BUILD_DOCS is or prebuilt documentation is available (like when building in-tree from a tarball). - FISH_USE_SYSTEM_PCRE2=ON|OFF - whether to use an installed pcre2. This is normally autodetected. - MAC_CODESIGN_ID=String|OFF - the codesign ID to use on Mac, or "OFF" to disable codesigning. - WITH_GETTEXT=ON|OFF - whether to build with gettext support for translations. Note that fish does *not* support static linking and will attempt to error out if it detects it. Help, it didn’t build! ~~~~~~~~~~~~~~~~~~~~~~ On Debian or Ubuntu you want these packages: :: sudo apt install build-essential cmake libpcre2-dev gettext On RedHat, CentOS, or Amazon EC2 everything should be preinstalled.
