spice-flow.sh

A flexible coordinate generator that enriches geographic points with random attributes. Like the spice melange flowing through the desert planet Arrakis, this script streams forth coordinates with mystical properties.

Usage

./spice-flow.sh <number_of_records> <number_of_attributes>

Arguments

• number_of_records: How many coordinate pairs to generate
• number_of_attributes: How many random values (0-9) to append to each coordinate pair

Example

./spice-flow.sh 100 10

This generates 100 records, each containing:

• A WGS 84 latitude (-90° to 90°)
• A WGS 84 longitude (-180° to 180°)
• 10 random integers (0-9)

Attribute Naming

Each attribute field now has a unique or semi-unique label drawn from a Dune-themed word list.

Output Format

The script saves results to a CSV file, named according to a random Dune-themed word, the total number of records, and the total number of attributes. For instance:

<random_dune_word>_<records>_<attributes>.csv

Each row consists of:

latitude,longitude,attr1,attr2,attr3,...

With latitude/longitude in decimal degrees and attributes as random integers.

Coordinate System

Coordinates are generated in WGS 84 (World Geodetic System 1984) format, the standard used by GPS and modern mapping applications.

• Latitude: -90° to 90° (negative for South, positive for North)
• Longitude: -180° to 180° (negative for West, positive for East)
• Three decimal places precision.

Additional Features

Execution Time Tracking
The script prints how many milliseconds it took to complete the process.

Requirements

• Bash shell
• awk

Performance

The script times its own execution in milliseconds and displays a summary upon completion, including how many records and attribute columns were generated, the final CSV filename, and the total run time.
