fish是一个智能且用户友好的命令行shell,适用于macOS,Linux和该系列的其他产品。Fish 包括语法突出显示、自动建议即键入和花哨的选项卡补全等功能,这些功能只需工作,无需配置。

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``, ``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
-  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)

Switching to fish

如果你希望使用 fish 作为默认外壳,请使用以下命令:


chsh -s /usr/local/bin/fish


如果尚未添加 fish,请使用以下命令以允许 fish 作为你的登录外壳:



echo /usr/local/bin/fish |sudo tee -a /etc/shells

要切换回默认 shell,你可以运行(替换为或根据需要)。

chsh -s /bin/bash




Compiling fish requires:

-  a C++11 compiler (g++ 4.8 or later, or clang 3.3 or later)
-  CMake (version 3.5 or later)
-  a curses implementation such as ncurses (headers and libraries)
-  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.

Building from source (all platforms) - Makefile generator

要安装 到 ,请运行:


..代码:: bash

mkdir 构建;光盘构建 cmake ..使须藤制作安装

可以使用 的参数更改安装目录。


从源代码构建 (macOS) - Xcode

Note: The minimum supported macOS version is 10.10 "Yosemite".

.. code:: bash

   mkdir build; cd build
   cmake .. -G Xcode

An Xcode project will now be available in the ``build`` subdirectory.
You can open it with Xcode, or run the following to build and install in

.. code:: bash

   xcodebuild -scheme 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!

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 install build-essential cmake ncurses-dev libncurses5-dev libpcre2-dev gettext

On RedHat, CentOS, or Amazon EC2:


   sudo yum install ncurses-devel
