try on your machine

The given command is using the ogrinfo utility, which is a part of the GDAL library, to interact with a GeoJSON file. Here's a breakdown of the command:

ogrinfo: The command-line utility for querying and analyzing geospatial data.

${path-to-input-geojson}: It is a placeholder for the path to the input GeoJSON file. You would need to replace it with the actual file path you want to operate on.

-dialect SQLite: Specifies that the SQL dialect used for the command is SQLite. SQLite is a lightweight database engine used within GDAL for various operations.

-sql "${UPDATE input SET attribute_name = 'foo'}": This is the SQL query being executed. It uses the SQL UPDATE statement to modify the data in the input GeoJSON file. The query is updating the attribute_name field in the input layer (assuming the existence of a layer with that name in the GeoJSON file) and setting its value to 'foo'.

To summarize, the command is updating the attribute_name field in a GeoJSON file using an SQL query through the ogrinfo utility.
