sd: Fast Find & Replace

Always invoke sd skill for find & replace operations - do not execute bash commands directly.

Use sd for intuitive text replacement that's 2-12x faster than sed.

When to Use sd vs ripgrep

Use sd when:

• Performing replacements on known patterns
• Batch text transformations across files
• Need JavaScript-style regex syntax
• Direct file modifications without search first

Use ripgrep when:

• Finding unknown patterns or locations
• Need search results without immediate changes
• Complex file filtering and type matching
• Want to preview before modifying

Common workflow: ripgrep skill → sd skill (search first, then replace)

Default Strategy

Invoke sd skill for fast find & replace operations. Use when performing replacements on known patterns, batch text transformations across files, or need JavaScript-style regex syntax.

Common workflow: ripgrep skill → sd skill (search first, then replace) or fd skill → sd skill for batch operations.

Key Options

• -F for string-literal mode (no regex)
• $1, $2 or ${var} for capture groups
• --preview to preview changes
• -- before patterns starting with -
• $$ for literal $ in replacement

When to Use

• Quick file edits
• Pipeline replacements: cat file | sd "old" "new"
• Batch operations across multiple files
• Complex regex with capture groups

Common Workflows

• fd → sd: Find files and perform batch replacements
• ripgrep | sd: Search patterns and replace across matches
• jq | sd: Extract JSON data and transform to other formats
• cat file | sd | bat: Transform content and preview with highlighting

Core Principle

Replace text with familiar JavaScript/Python regex syntax - no sed escape hell.

Skill Combinations

For Discovery Phase

• ripgrep → sd: Search patterns first, then replace across matches
• fd → sd: Find files and perform batch replacements
• jq/yq → sd: Extract data and transform to other formats

For Analysis Phase

• sd --preview → bat: Preview changes with syntax highlighting
• sd → fzf: Interactive selection of changes to apply
• sd → jq/yq: Transform data back to structured formats

For Refactoring Phase

• sd → searching-text: Verify replacements didn't introduce issues
• sd → analyzing-code-structure: Follow up with structural changes if needed
• sd → analyzing-code: Measure impact of text-based changes

Integration Examples

# Find and replace across project
fd -e js -x sd "oldPattern" "newPattern" --preview

# Chain transformations
cat config.json | jq '.version' | sd '"v' '' | sd '"' '' | xargs git tag

# Interactive replacement with preview
rg "deprecated" -l | fzf --multi | xargs sd "deprecated" "legacy" --preview | bat
