Konrad Borowski d61adfbc53 Ensure that UTF-8 works if LANG contains it. 
Some people like to have their terminals claim UTF-8 support when
their terminals actually are set to another encoding. As nobody
appears to understand this, I have made a change to automatically
fix the encoding problems if possible. This uses ISO 2022 sequences
in order to dynamically change the encoding.

Fixes #692. Fixes #895. Fixes possible future issues about this.

Changed fish to no longer validate changes to PATH unless the paths are new (i.e. don't recheck what's already there).

README.md

fish - the friendly interactive 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.

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 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 requires gettext for translation support.

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

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.

Optional Dependencies

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.

Contact Us

Questions, comments, rants and raves can be posted to the official fish mailing list at https://lists.sourceforge.net/lists/listinfo/fish-users or join us on our IRC channel #fish at irc.oftc.net.
