Bayesh

Your shell history, smarter and faster.

What is Bayesh?

Bayesh is your personal shell assistant, designed to make your command-line experience smoother and more efficient. It learns from your shell history and suggests commands you’ve used before. Powered by fzf, Bayesh brings a sleek and intuitive UI to your terminal.

Why Bayesh? 🤔

• Save Time: Stop retyping or searching for commands you’ve already used.
• Stay Focused: Let Bayesh handle the repetitive stuff while you focus on what matters.
• Privacy First: Bayesh only learns from your history—no external data, no surprises. Your data stays with you and is never uploaded anywhere.
• Zsh First, Bash Friendly: While optimized for Z-shell (zsh), Bayesh works great with bash too.

Why You'll Love Bayesh ❤️

Think of Bayesh as the auto-suggestion feature on your smartphone—but for your terminal. It’s like having a personal assistant that remembers everything you’ve done and helps you do it faster.

Key Features:

• No Guesswork: Bayesh only suggests commands you’ve actually used.
• Quick Learning: It starts being useful after just a short learning phase.
• Customizable: Works seamlessly with your shell setup.

Gotchas ⚠️

Bayesh relies on your shell’s history behavior. To get the best experience:

• For Bash Users:
  Add this to your ~/.bashrc:

  export HISTCONTROL=

• For Zsh Users:
  Add this to your ~/.zshrc:

  unsetopt HIST_IGNORE_DUPS

Test your setup by running history -1 twice. If the two lines are different (timestamps or event numbers), you’re good to go!

Inspirations 🌟

Bayesh draws inspiration from:

• autojump, z, and zoxide
• The incredible fzf
• Peter Norvig's legendary blogpost on building a spelling corrector
