[fish](https://fishshell.com/) - the friendly interactive shell [](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 <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](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
|
|
|
|
Sphinx is also optionally required to build the documentation from a cloned git repository.
|
|
|
|
### Building from source (all platforms) - Makefile generator
|
|
|
|
To install into `/usr/local`, run:
|
|
|
|
```bash
|
|
mkdir build; cd build
|
|
cmake ..
|
|
make
|
|
sudo make install
|
|
```
|
|
|
|
The install directory can be changed using the `-DCMAKE_INSTALL_PREFIX` parameter for `cmake`.
|
|
|
|
### Building from source (macOS) - Xcode
|
|
|
|
```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 `/usr/local`:
|
|
|
|
```bash
|
|
xcodebuild
|
|
xcodebuild -scheme install
|
|
```
|
|
|
|
The install directory can be changed using the `-DCMAKE_INSTALL_PREFIX` parameter for `cmake`.
|
|
|
|
### 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
|
|
