# Find Replace Modern find-and-replace using sd. ## sd Basics ```bash # Replace in file (in-place) sd 'oldText' 'newText' file.txt # Replace in multiple files sd 'oldText' 'newText' *.js # Preview without changing (pipe) cat file.txt | sd 'old' 'new' ``` ## sd vs sed | sed | sd | |-----|-----| | `sed 's/old/new/g'` | `sd 'old' 'new'` | | `sed -i 's/old/new/g'` | `sd 'old' 'new' file` | | `sed 's#path/to#new/path#g'` | `sd 'path/to' 'new/path'` | **Key difference:** sd is global by default, no delimiter issues. ## Common Patterns ```bash # Variable/function rename sd 'oldName' 'newName' src/**/*.ts # Word boundaries (avoid partial matches) sd '\boldName\b' 'newName' src/**/*.ts # Import path update sd "from '../utils'" "from '@/utils'" src/**/*.ts # Capture groups sd 'console\.log\((.*)\)' 'logger.info($1)' src/**/*.js ``` ## Safe Batch Workflow ```bash # 1. List affected files rg -l 'oldPattern' src/ # 2. Preview replacements rg 'oldPattern' -r 'newPattern' src/ # 3. Apply sd 'oldPattern' 'newPattern' $(rg -l 'oldPattern' src/) # 4. Verify rg 'oldPattern' src/ # Should return nothing git diff # Review changes ``` ## Special Characters | Character | Escape | |-----------|--------| | `.` | `\.` | | `*` | `\*` | | `[` `]` | `\[` `\]` | | `$` | `\$` | | `\` | `\\` | ## Tips | Tip | Reason | |-----|--------| | Always preview with `rg -r` first | Avoid mistakes | | Use git before bulk changes | Easy rollback | | Use `\b` for word boundaries | Avo
