description: Control display brightness and safely move files to trash instead of permanently deleting with rm.

# Display & Safety
## brightness
```bash
# Get current brightness (0.0 to 1.0)
brightness -l
# Set brightness to 80%
brightness 0.8
# Set brightness to minimum
brightness 0.0
# Set brightness to maximum
brightness 1.0
```
## trash (macos-trash)
Safe alternative to `rm` — moves files to macOS Trash:
```bash
# Move file to trash
trash file.txt
# Move multiple files
trash file1.txt file2.txt dir/
# Move with confirmation prompt
trash --interactive file.txt
```
## Guidelines
- Use `trash` instead of `rm` when the user might want to recover files
- Use `rm` only for temporary/generated files where recovery isn't needed
- Brightness value is 0.0 (off) to 1.0 (max)
- `brightness -l` lists all displays when multiple monitors connected
