David Adam 209d8b7f2f Fix for CVE-2014-2905 - fishd restart required. 
- Use a secure path for sockets (some code used under license from
   tmux).
 - Provide the secure path in the environment as $__fish_runtime_dir.
 - Link the new path to the old path to ease migration from earlier
   versions.

Closes #1359.

After installing fish built from or after this commit, you MUST
terminate all running fishd processes (`killall fishd`, `pkill fishd`
or similar). Distributors are encouraged to do this from within their
packaging scripts. fishd will restart automatically, and no data should
be lost.

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 are documented at http://ridiculousfish.com/shell/faq.html

Detailed user documentation is available by running help within fish, and also at http://ridiculousfish.com/shell/user_doc/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.

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 libncursesw5-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.

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
