Configuration
Configuration Files
Global ignore file locations:
- Linux/macOS:
~/.config/fd/ignore or ~/.fdignore
- Windows:
%APPDATA%\fd\ignore
Project-specific: .fdignore in project root
.fdignore File Example
# Ignore dependency directories
node_modules/
vendor/
target/
# Ignore build outputs
build/
dist/
*.o
*.pyc
# Ignore IDE directories
.idea/
.vscode/
*.swp
# Ignore log files
*.log
logs/
# Ignore temporary files
*.tmp
*~
.DS_Store
# Ignore specific paths
/cache/
/tmp/
Environment Variables
# Set default options for all fd commands
export FD_OPTS="--hidden --follow --exclude .git"
# Control colorization (fd respects LS_COLORS)
export LS_COLORS="di=34:ln=35:ex=31:*.txt=33"
Useful Aliases
# Add to ~/.bashrc or ~/.zshrc
# Search including hidden files
alias fdh='fd -H'
# Search ignoring .gitignore
alias fda='fd -I'
# Find large files
alias fdl='fd --size +100m'
# Find recent files (last 24 hours)
alias fdr='fd --changed-within 1d'
# Find and preview with fzf and bat
alias fdf='fd -t f | fzf --preview "bat --color=always {}"'
# Find and edit with vim
alias fdv='fd -t f | fzf | xargs -r vim'
Common Use Cases
Use Case 1: Clean Build Artifacts
# Remove all Python compiled files
fd -e pyc -e pyo -x rm {}
# Remove all node_modules directories (up to 2 levels deep)
fd -t d -d 2 '^node_modules$' -x rm -rf {}
# Clean old log files (older than 30 days)
fd -e log --changed-before 30d -x rm {}
# Remove all temporary files
fd -g '*.tmp' -g '*~' -g '*.swp' -x rm {}
Use Case 2: Code Search and Analysis
# Find all JavaScript/TypeScript files modified in last week
fd -e js -e ts -e jsx -e tsx --changed-within 7d
# Count lines of code in Rust project
fd -e rs -x wc -l {} | awk '{sum+=$1} END {print sum}'
# Find all TODO comments in Python files
fd -e py -x grep -Hn "TODO:" {}
# Find largest source files
fd -e java -e kt -x du -h {} | sort -hr | head -20
# Find files containing specific function name
fd -e cpp -e hpp -x grep -l "myFunction" {}
Use Case 3: Log File Management
# Find and compress logs older than 7 days
fd -e log --changed-before 7d -x gzip {}
# Search for errors in recent logs
fd -e log --changed-within 1d -x grep -i "error" {} \;
# Find large log files (over 100MB)
fd -e log --size +100m -l
# Archive old logs to separate directory
fd -e log --changed-before 30d -x mv {} /archive/logs/
Use Case 4: Docker and Container Management
# Find all Dockerfiles in project
fd -g '*Dockerfile*' -g 'Dockerfile.*'
# Find all docker-compose files
fd -g 'docker-compose*.yml' -g 'docker-compose*.yaml'
# Find and validate Dockerfiles
fd '^Dockerfile$' -x docker build --dry-run -f {} .
# Find container-related configs
fd -e yml -e yaml -x grep -l "kind:" {} \;
Use Case 5: Security and Permissions Audit
# Find world-writable files (security risk)
fd -t f -x sh -c 'test -w {} && ls -l {}'
# Find SUID/SGID binaries
fd -t x -x sh -c 'test -u {} -o -g {} && ls -l {}'
# Find files with passwords in name
fd -i password -i passwd -i secret
# Find configuration files with potential secrets
fd -g '*.conf' -g '*.cfg' -g '*.ini' -x grep -i "password\|secret\|key" {}
# Find SSH keys
fd -g 'id_rsa*' -g 'id_ed25519*' -H
Best Practices
- Use
.fdignore files: Create project-specific ignore patterns to speed up searches and reduce noise
- Leverage smart defaults:
fd automatically respects .gitignore - use -I only when you need ignored files
- Combine with other tools: Pipe
fd output to xargs, grep, or fzf for powerful workflows
- Use
-0 with xargs: Always use fd -0 | xargs -0 for filenames with spaces or special characters
- Prefer
-x over pipes: Use fd -x command {} instead of piping to xargs for better performance
- Set depth limits: Use
-d flag on large directory trees to prevent excessive recursion
- Use specific type filters: Filter by type (
-t f, -t d) early to reduce search space
- Create aliases: Set up shell aliases for frequently used
fd patterns to save typing
- Combine time and size filters: Use
--changed-within and --size together for precise file targeting
- Test regex patterns: Use online regex testers before complex
fd searches to verify patterns
Troubleshooting
| Issue | Solution |
|---|
Command not found: fd | On Debian/Ubuntu, binary is fdfind. Create symlink: ln -s $(which fdfind) ~/.local/bin/fd |
| Too many results | Use depth limit -d 3, exclude patterns -E node_modules, or filter by type -t f |
| Not finding hidden files | Add -H flag to include hidden files, or -HI to also ignore .gitignore rules |
| Search is too slow | Reduce depth with -d, exclude large directories with -E, or use --threads to control parallelism |
| Regex not matching | Remember fd uses case-insensitive search by default. Use -s for case-sensitive or -F for literal strings |
| Files in .gitignore showing up | This shouldn’t happen by default. Check for -I or --no-ignore flags in aliases or FD_OPTS |
| Special characters in filenames breaking commands | Use -0 with xargs -0 or use -x flag instead: fd pattern -x command {} |
| Cannot execute command on results | Check if using correct syntax: -x for individual execution, -X for batch execution |
| Color output in logs/files | Disable with --color never or redirect stderr: fd pattern 2>/dev/null |
| Permission denied errors | Redirect stderr to ignore: fd pattern 2>/dev/null or run with appropriate permissions |
| Not respecting .fdignore file | Ensure .fdignore is in project root or ~/.config/fd/ignore. Check file syntax matches .gitignore format |
