[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
|
|
|
|
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.
