Gh Search Commits

GitHub CLI: Search Commits

Overview

Search for commits across GitHub repositories using gh search commits. Filter by author, committer, dates, commit hashes, and more.

When to Use This Skill

Use this skill when searching commits across GitHub:

• Finding commits by author or committer across repos/orgs
• Searching commit messages for keywords across repositories
• Filtering by commit dates or hashes in specific repos
• Looking for merge commits across an organization
• Searching in specific repositories or organizations
• Need to exclude certain results (requires -- flag)

Syntax

gh search commits [<query>] [flags]

Key Flags Reference

Author & Committer Filters

Commit Attributes

Repository Filters

JSON Output Fields

Available fields: author, commit, committer, id, parents, repository, sha, url

Exclusion Syntax (Critical!)

When using inline query exclusions (negations with -), you MUST use the -- separator:

✅ Correct: gh search commits -- "search-terms -qualifier:value" ❌ Wrong: gh search commits "search-terms" --flag=-value ❌ Wrong: gh search commits "search-terms" --flag=!value ❌ Wrong: gh search commits --author-not=username

Examples:

• gh search commits -- "fix -author:dependabot" (exclude author)
• gh search commits -- "merge -committer:bot" (exclude committer)
• gh search commits -- "deploy -merge:true" (exclude merge commits)
• gh search commits -- "refactor -author-date:<2024-01-01" (exclude date range)

Why the -- separator is required: The -- tells the shell to stop parsing flags and treat everything after it as arguments. Without it, -qualifier:value inside quotes may be misinterpreted.

Critical Syntax Rules

When to Use Flag Syntax vs Query Syntax

Decision Tree:

Does your search include:
  - Any exclusions (NOT, minus, without, except)?  → Use Query Syntax with `--`
  - Complex boolean logic (OR, AND)?              → Use Query Syntax with `--`

Otherwise:
  - Simple positive filters only?                  → Use Flag Syntax

Flag Syntax (for positive filters):

gh search commits "bug fix" --author octocat --repo cli/cli

Query Syntax with -- (required for exclusions):

gh search commits -- "deploy -author:dependabot -author:renovate"

⚠️ NEVER mix both syntaxes in a single command!

1. Exclusions and Negations

CRITICAL: When excluding results, you MUST use query syntax with the -- separator.

Exclusion Syntax Rules:

1. Use the -- separator before your query
2. Use -qualifier:value format (dash prefix for negation)
3. Quote the entire query string

Examples:

Single exclusion:

# Exclude specific author
gh search commits -- "deploy -author:dependabot"

# Exclude specific committer
gh search commits -- "merge -committer:bot"

# Exclude merge commits
gh search commits -- "fix -merge:true"

Multiple exclusions:

# Exclude multiple authors
gh search commits -- "deployment -author:dependabot -author:renovate"

# Exclude author and date range
gh search commits -- "refactor -author:bot -author-date:<2024-01-01"

# Exclude merge commits and specific authors
gh search commits -- "feature -merge:true -author:bot"

Combine with positive filters using flags:

# Wrong - mixing syntaxes:
gh search commits "fix" --author octocat -committer:bot  # ❌

# Correct - use query syntax for everything when excluding:
gh search commits -- "fix author:octocat -committer:bot"  # ✅

PowerShell exclusions:

# Use --% to prevent PowerShell parsing
gh --% search commits -- "fix -author:dependabot"

Common Exclusion Patterns:

2. Date Formats

Use ISO8601 format (YYYY-MM-DD) with comparison operators:

gh search commits --author-date ">2024-01-01"
gh search commits --committer-date "2024-01-01..2024-12-31"

3. Quoting Rules

Multi-word search:

gh search commits "bug fix"

Date comparisons need quotes:

gh search commits "refactor" --author-date "<2024-06-01"

Common Use Cases

Find commits by author:

gh search commits --author octocat --repo cli/cli

Search commit messages:

gh search commits "security fix" --repo myorg/myrepo

Find commits in date range:

gh search commits "refactor" --author-date "2024-01-01..2024-12-31"

Find merge commits:

gh search commits --merge --repo owner/repo

Exclude bot commits:

gh search commits -- "deployment -author:dependabot"

Search by commit hash:

gh search commits --hash 8dd03144

Find commits by email:

gh search commits --author-email user@example.com

Common Mistakes

Installation Check

If gh command not found:

# Check if gh is installed
which gh

# Install: https://cli.github.com/manual/installation

If not authenticated:

# Authenticate with GitHub
gh auth login

Date Comparison Operators

• > - After date
• >= - On or after date
• < - Before date
• <= - On or before date
• .. - Date range: 2024-01-01..2024-12-31
