Command Line Interface

# Get dataset information
fio info data.shp

# List layers in multi-layer dataset  
fio ls database.gpkg

# Print dataset bounds
fio bounds data.shp

# Print environment information
fio env

# Print features as GeoJSON
fio cat data.shp

# Dump features to output format
fio dump --format GeoJSON data.shp > output.geojson

# Collect features into collections
fio collect input1.shp input2.shp > combined.geojson

# Load features from input
fio load --format Shapefile < input.geojson

# Remove datasets or layers
fio rm unwanted.shp
fio rm database.gpkg --layer temp_layer

# Interactive inspection
fio insp data.shp

# Filter features with expressions
fio cat data.shp | fio filter "properties.population > 100000"

# Transform/map features
fio cat data.shp | fio map "properties.area = properties.area * 0.0001"

# Reduce features with expressions  
fio cat data.shp | fio reduce "sum(properties.population)"

# Convert shapefile to GeoJSON
fio cat input.shp > output.geojson

# Get basic information about a dataset
fio info /path/to/data.gpkg
# Output: driver, layer count, bounds, CRS, etc.

# List all layers in a GeoPackage
fio ls database.gpkg
# Output: layer1, layer2, layer3

# Get bounds of a dataset
fio bounds data.shp  
# Output: minx miny maxx maxy

# Print features with pretty formatting
fio cat --precision 2 data.geojson
