 Other shells such as bash and zsh use a variable named ``HISTFILE`` for a similar purpose. Fish uses a different name to avoid conflicts and signal that the behavior is different (session name instead of a file path). Also, if you set the var to anything other than ``fish`` or ``default`` it will inhibit importing the bash history.
