Common patterns

# Find all Python files
fd -e py

# Find multiple extensions
fd -e py -e js -e ts

# Find directories only
fd -t d pattern

# Find files only
fd -t f pattern

# Find symlinks
fd -t l

Advanced Usage

Filtering

# Exclude patterns
fd pattern -E "node_modules" -E "*.min.js"

# Include hidden files
fd -H pattern

# Include ignored files (.gitignore)
fd -I pattern

# Search all (hidden + ignored)
fd -H -I pattern

# Maximum depth
fd pattern -d 3

Execution

# Execute command on results
fd -e jpg -x convert {} {.}.png

# Parallel execution
fd -e md -x wc -l

# Use with xargs
fd -e log -0 | xargs -0 rm

Regex patterns

# Full regex search
fd '^test.*\.js$'

# Match full path
fd --full-path 'src/.*/test'

# Glob pattern
fd -g "*.{js,ts}"

Time-based filtering

# Modified within last day
fd --changed-within 1d

# Modified before specific date
fd --changed-before 2024-01-01

# Created recently
fd --changed-within 1h

Size filtering

# Files larger than 10MB
fd --size +10m

# Files smaller than 1KB
fd --size -1k

# Specific size range
fd --size +100k --size -10m

Output formatting

# Absolute paths
fd --absolute-path

# List format (like ls -l)
fd --list-details

# Null separator (for xargs)
fd -0 pattern

# Color always/never/auto
fd --color always pattern

Common Use Cases

Find and delete old files:

fd --changed-before 30d -t f -x rm {}

Find large files:

fd --size +100m --list-details

Copy all PDFs to directory:

fd -e pdf -x cp {} /target/dir/

Count lines in all Python files:

fd -e py -x wc -l | awk '{sum+=$1} END {print sum}'

Find broken symlinks:

fd -t l -x test -e {} \; -print

Search in specific time window:

fd --changed-within 2d --changed-before 1d

Integration with other tools

With ripgrep:

fd -e js | xargs rg "pattern"

With fzf (fuzzy finder):

vim $(fd -t f | fzf)

With bat (cat alternative):

fd -e md | xargs bat

Performance Tips

fd is typically much faster than find
Respects .gitignore by default (disable with -I)
Uses parallel traversal automatically
Smart case: lowercase = case-insensitive, any uppercase = case-sensitive

Tips

Use -t for type filtering (f=file, d=directory, l=symlink, x=executable)
-e for extension is simpler than -g "*.ext"
{} in -x commands represents the found path
{.} strips the extension
{/} gets basename, {//} gets directory
