fish is a user friendly commandline shell intended mostly for interactive use.

Installation instructions

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:

$ less /etc/shells

If you wanted to make fish your default shell run:

$ chsh -s /usr/bin/fish

Pacman and fish

Context-aware completions for pacman and makepkg are built into 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.


After you change your default shell to fish, you may find that you no longer have very much in your path. You can add a section to your ~/.config/fish/ file that will set your path correctly on login. This is much like .profile or .bash_profile as it is only executed for login shells.

if status --is-login
    set PATH $PATH /usr/bin /sbin
