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.

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/

fish can be built using autotools or Xcode.

autoconf
./configure [--without-xsel]
make [gmake on BSD]
sudo make install

• Build the base target in Xcode
• Run the fish executable, for example, in DerivedData/fish/Build/Products/Debug/base/bin/fish

xcodebuild install
sudo ditto /tmp/fish.dst /
