Find Replace

Modern find-and-replace using sd.

sd Basics

# 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

# 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

# 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	Avoid partial matches
Quote patterns	Prevent shell interpretation
