zhist

A shell history tool for zsh, written in Go. It records every command with its working directory, exit status, and duration. It replaces the zsh history file as the persistent store.

Purpose

Native zsh history stores a command and a timestamp, nothing else. zhist stores context: where you ran a command, whether it failed, and how long it took. The fzf picker uses that context. Failed commands show in red, and each entry shows its duration. One key toggles between global history and the current directory's history.

Install

Homebrew (recommended):

brew install overflowy/tap/zhist

Go:

go install github.com/overflowy/zhist@latest

zinit, downloading the binary from GitHub releases:

zinit ice from"gh-r" as"program"
zinit light overflowy/zhist

Requires fzf 0.45 or newer for the picker. Homebrew installs it as a dependency.

Setup

Add to .zshrc:

eval "$(zhist init)"

Plugin managers can source zhist.plugin.zsh instead, which runs the same line. Example with zsh-snap:

znap source overflowy/zhist

The plugin file only loads the integration. Install the binary with Homebrew, Go, or zinit first.

Import existing history once:

zhist import ~/.zsh_history

Imported entries have no directory, exit status, or duration. They show a blank directory and never render red.

Keys

Pass -no-arrow-binds to zhist init to keep the default up/down behavior. Only ctrl-r opens the picker then.

Ignoring commands

Define a HIST_EXCLUDE array in .zshrc to keep commands out of the store. zhist skips a command when its first word is in the array.

HIST_EXCLUDE=(cd ls clear pwd exit)

• Matching is exact and case-sensitive, on the first word only. ls skips ls -la but not lsd.
• For multiline commands the first word of the first line decides.
• The hook reads the array at record time. Change it in a running shell and the change applies to the next command.
• A leading space also skips recording, for one-off exclusions.

Inline suggestions

zhist search prints stored commands matching a prefix, newest first, with repeated runs collapsed. It exits 1 when nothing matches. This gives zsh-autosuggestions fish-style ghost text backed by the zhist store instead of the zsh history file:

_zsh_autosuggest_strategy_zhist() {
	suggestion=$(zhist search -limit 1 -- "$1")
}
ZSH_AUTOSUGGEST_STRATEGY=(zhist)

The -- keeps a buffer starting with - from being parsed as a flag.

Recommended zsh history settings

zhist owns persistence. Keep native history in memory only, for line stepping and ! expansion within a session.

unset HISTFILE  # macOS /etc/zshrc sets it; unset stops zsh reading or writing the file
HISTSIZE=100000 # In-memory events for up-arrow and ! expansion
SAVEHIST=0      # Never write a history file

setopt BANG_HIST            # Treat the '!' character specially during expansion
setopt HIST_IGNORE_DUPS     # Don't record an entry that was just recorded again
setopt HIST_IGNORE_ALL_DUPS # Delete old recorded entry if new entry is a duplicate
setopt HIST_FIND_NO_DUPS    # Do not display a line previously found
setopt HIST_IGNORE_SPACE    # Don't record an entry starting with a space
setopt HIST_REDUCE_BLANKS   # Remove superfluous blanks before recording entry
setopt HIST_VERIFY          # Do not execute immediately upon history expansion

Do not set SHARE_HISTORY, INC_APPEND_HISTORY, or EXTENDED_HISTORY. They only affect the history file, which zhist replaces.

Compatibility notes:

• Commands with a leading space are not recorded. This matches HIST_IGNORE_SPACE.
• eval "$(zhist init)" must run after plugins that bind ctrl-r or the arrow keys (atuin, zsh-history-substring-search, prompt pickers). The last bind wins.
• The record hook prepends itself to precmd_functions and passes $? through. Prompts that read the exit status in their own precmd keep working.
