fish is a user friendly commandline shell intended mostly for interactive use.
To install the package for fish using pacman (the package is in the community repo) run:
pacman -S fish
To verify that it has been installed you can run:
If you wanted to make fish your default shell run:
chsh -s /usr/bin/fish
Pacman and fish
There are now the completions of pacman and makepkg for fish. Look in the AUR for the fish-pacman package. These completions are likely to be included in the next upstream relase of fish, since the policy of the fish development is to include all the existent completions in the upstream tarball. The memory management is clever enough to avoid any negative impact on resources.
If you notice that your $PATH has become /bin and /usr/bin, type in $PATH at the fish prompt. This will display a nifty note telling you how to set the path using a function.
