[fish](https://fishshell.com/) - the friendly interactive shell [![Build Status](https://travis-ci.org/fish-shell/fish-shell.svg?branch=master)](https://travis-ci.org/fish-shell/fish-shell) ================================================ fish is a smart and user-friendly command line shell for macOS, Linux, and the rest of the family. fish includes features like syntax highlighting, autosuggest-as-you-type, and fancy tab completions that just work, with no configuration required. For more on fish's design philosophy, see the [design document](https://fishshell.com/docs/current/design.html). ## Quick Start fish generally works like other shells, like bash or zsh. A few important differences can be found at by searching for the magic phrase "unlike other shells". Detailed user documentation is available by running `help` within fish, and also at You can quickly play with fish right in your browser by clicking the button below: [![Try in browser](https://cdn.rawgit.com/rootnroll/library/assets/try.svg)](https://rootnroll.com/d/fish-shell/) ## Getting fish ### macOS fish can be installed: * using [Homebrew](http://brew.sh/): `brew install fish` * using [MacPorts](https://www.macports.org/): `sudo port install fish` * using the [installer from fishshell.com](https://fishshell.com/) * as a [standalone app from fishshell.com](https://fishshell.com/) ### Packages for Linux Packages for Debian, Fedora, openSUSE, and Red Hat Enterprise Linux/CentOS are available from the [openSUSE Build Service](https://software.opensuse.org/download.html?project=shells%3Afish&package=fish). Packages for Ubuntu are available from the [fish PPA](https://launchpad.net/~fish-shell/+archive/ubuntu/release-3), and can be installed using the following commands: ``` sudo apt-add-repository ppa:fish-shell/release-3 sudo apt-get update sudo apt-get install fish ``` Instructions for other distributions may be found at [fishshell.com](https://fishshell.com). ### Windows - On Windows 10, fish can be installed under the WSL Windows Subsystem for Linux with `sudo apt install fish` or from source with the instructions below. - Fish can also be installed on all versions of Windows using [Cygwin](https://cygwin.com/) (from the **Shells** category). ### Building from source If packages are not available for your platform, GPG-signed tarballs are available from [fishshell.com](https://fishshell.com/) and [fish-shell on GitHub](https://github.com/fish-shell/fish-shell/releases). See the *Building* section for instructions. ## Running fish Once installed, run `fish` from your current shell to try fish out! ### Dependencies Running fish requires: * curses or ncurses (preinstalled on most \*nix systems) * some common \*nix system utilities (currently `mktemp`), in addition to the basic POSIX utilities (`cat`, `cut`, `dirname`, `ls`, `mkdir`, `mkfifo`, `rm`, `sort`, `tr`, `uname` and `sed` at least, but the full coreutils plus find, sed and awk is preferred) * gettext (library and `gettext` command), 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 `ul` and either `nroff` or `mandoc` for display * automated completion generation from manual pages requires Python (2.7+ or 3.3+) and possibly the `backports.lzma` module for Python 2.7 * the `fish_config` web configuration tool requires Python (2.7+ or 3.3 +) 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 ### Switching to fish If you wish to use fish as your default shell, use the following command: chsh -s /usr/local/bin/fish `chsh` will prompt you for your password and change your default shell. (Substitute `/usr/local/bin/fish` with whatever path fish was installed to, if it differs.) Use the following command if fish isn't already added to `/etc/shells` to permit fish to be your login shell: echo /usr/local/bin/fish | sudo tee -a /etc/shells To switch your default shell back, you can run `chsh -s /bin/bash` (substituting `/bin/bash` with `/bin/tcsh` or `/bin/zsh` as appropriate). ## Building ### Dependencies Compiling fish requires: * a C++11 compiler (g++ 4.8 or later, or clang 3.3 or later) * CMake (version 3.2 or later) * a curses implementation such as ncurses (headers and libraries) * PCRE2 (headers and libraries) - a copy is included with fish * gettext (headers and libraries) - optional, for translation support Doxygen (1.8.7 or later) is also optionally required to build the documentation from a cloned git repository. ### Building from source (all platforms) - Makefile generator ```bash mkdir build; cd build cmake .. make sudo make install ``` ### Building from source (macOS) - Xcode ```bash mkdir build; cd build cmake .. -G Xcode ``` An Xcode project will now be available in the `build` subdirectory. ### Help, it didn't build! If fish reports that it could not find curses, try installing a curses development package and build again. On Debian or Ubuntu you want: sudo apt-get install build-essential cmake ncurses-dev libncurses5-dev libpcre2-dev gettext On RedHat, CentOS, or Amazon EC2: sudo yum install ncurses-devel ## Contributing Changes to the Code See the [Guide for Developers](CONTRIBUTING.md). ## Contact Us Questions, comments, rants and raves can be posted to the official fish mailing list at or join us on our [gitter.im channel](https://gitter.im/fish-shell/fish-shell) or IRC channel [#fish at irc.oftc.net](https://webchat.oftc.net/?channels=fish).
