Migrating from Fish shell to Zsh? Need your history? Just convert it to the correct format.
Clone it, install NPM dependencies (nvm use && npm i) and...
node index.js >> ~/.zsh_history
to append it to your .zsh_history.
or run a docker container
docker build -t fish-history-to-zsh .
docker run --rm -v $HOME/.local/share/fish/fish_history:/root/.local/share/fish/fish_history fish-history-to-zsh >> ~/.zsh_history
Have fun!
