Bayesh

Make better use of your shell history!

What is Bayesh?

Bayesh is the auto-suggestion feature on your phone when you write messages — but for your terminal! Bayesh suggests shell commands to you in real time, based on your shell history. Bayesh is lightening fast ⚡ (written in Go) and powered by fzf for great UX. Bayesh supports Bash and Zsh shells. Zsh in tmux is where Bayesh really shines ☀️.

Installation

1. Install Dependencies:
   Ensure you have the following installed: fzf, jq, tmux (tmux is only required for the Zsh shell)

2. Install Bayesh:
   To install Bayesh run

curl -sL https://raw.githubusercontent.com/mads-bisgaard/bayesh/refs/heads/main/install.sh | bash

3. Go!
   Make sure to integrate Bayesh into your shell. Close and reopen your shell and hit Ctrl-e to open bayesh.

Shell integration

• To integrate Bayesh into Zsh, add source <(bayesh --zsh) to your configuration file. You can do so by running

echo "command -v bayesh > /dev/null && source <(bayesh --zsh)" >> ~/.zshrc

• To integrate Bayesh into Bash, add source <(bayesh --bash) to your configuration file. You can do so by running

echo "command -v bayesh > /dev/null && source <(bayesh --bash)" >> ~/.bashrc

How to Use Bayesh

Bayesh is triggered by hitting Ctrl-e in your shell.

When using Zsh shell in tmux you

• toggle the fzf pane with Ctrl-<up arrow> and Ctrl-<down arrow>.
• select a suggestion with Ctrl-<right arrow>.

At first Bayesh has a short "learning phase" before it will start suggesting you commands.

Inspirations

Bayesh draws inspiration from:

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

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!

• Bayesh is built with CGO_ENABLED=1, so it relies on glibc being available at run time.
