This is a simple script that converts your fish shell history to zsh history.
This script wasn't really tested, so use it at your own risk.
Requires Bun.
# To preview output to stdout
bun x github:imcatwhocode/fish-to-zsh-history
# If you brave enough
bun x github:imcatwhocode/fish-to-zsh-history > ~/.zsh_history
