[fish](http://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 OS X, 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](http://fishshell.com/docs/2.0/design.html).
|
|
|
|
## Quick Start
|
|
|
|
fish generally works like other shells, like bash or zsh. A few important differences can be found at <http://fishshell.com/tutorial.html> by searching for the magic phrase 'unlike other shells'.
|
|
|
|
Detailed user documentation is available by running `help` within fish, and also at <http://fishshell.com/docs/2.0/index.html>
|
|
|
|
## Building
|
|
|
|
fish is written in a sane subset of C++98, with a few components from C++TR1. It builds successfully with g++ 4.2 or later, and with clang. It also will build as C++11.
|
|
|
|
fish can be built using autotools or Xcode. autoconf 2.60 or later is required.
|
|
|
|
fish depends on a curses implementation, such as ncurses. The headers and libraries are required for building.
|
|
|
|
fish requires gettext for translation support.
|
|
|
|
Building the documentation requires Doxygen 1.5 or newer.
|
|
|
|
### Autotools Build
|
|
|
|
autoconf
|
|
./configure
|
|
make [gmake on BSD]
|
|
sudo make install
|
|
|
|
### Xcode Development Build
|
|
|
|
* Build the `base` target in Xcode
|
|
* Run the fish executable, for example, in `DerivedData/fish/Build/Products/Debug/base/bin/fish`
|
|
|
|
### Xcode Build and Install
|
|
|
|
xcodebuild install
|
|
sudo ditto /tmp/fish.dst /
|
|
|
|
## 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 libncurses5-dev
|
|
|
|
On RedHat, CentOS, or Amazon EC2:
|
|
|
|
sudo yum install ncurses-devel
|
|
|
|
## Runtime Dependencies
|
|
|
|
fish requires a curses implementation, such as ncurses, to run.
|
|
|
|
fish requires a number of utilities to operate, which should be present on any Unix, GNU/Linux or OS X system. These include (but are not limited to) hostname, grep, awk, sed, which, and getopt. fish also requires the bc program.
|
|
|
|
Translation support requires the gettext program.
|
|
|
|
Some optional features of fish, such as the manual page completion parser and the web configuration tool, require Python.
|
|
|
|
In order to generate completions from man pages compressed with either lzma or xz, you may need to install an extra Python package. Python versions prior to 2.6 are not supported. For Python versions 2.6 to 3.2 you need to install the module `backports.lzma`. How to install it depends on your system and how you installed Python. Most Linux distributions should include it as a package named `backports-lzma` (or similar). From version 3.3 onwards, Python already includes the required module.
|
|
|
|
## Packages for Linux
|
|
|
|
Instructions on how to find builds for several Linux distros are at <https://github.com/fish-shell/fish-shell/wiki/Nightly-builds>
|
|
|
|
## 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.
|
|
|
|
To switch your default shell back, you can run:
|
|
|
|
chsh -s /bin/bash
|
|
|
|
Substitute /bin/bash with /bin/tcsh or /bin/zsh as appropriate.
