[fish](http://fishshell.com/) - 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](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 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
Nightly builds for several Linux distros can be downloaded from <http://download.opensuse.org/repositories/home:/siteshwar/>
## 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](https://webchat.oftc.net/?channels=fish).
