ogrinfo - Lists information about an OGR supported data source.

The ogrinfo program lists various information about an OGR supported data source to stdout (the terminal).
If no layer names are passed then ogrinfo will report a list of available layers (and their layer wide geometry type). If layer name(s) are given then their extents, coordinate system, feature count, geometry type, schema and all features matching query parameters will be reported to the terminal. If no query parameters are provided, all features are reported.
Geometries are reported in OGC WKT format.
Example reporting all layers in an NTF file:
% ogrinfo wrk/SHETLAND_ISLANDS.NTF INFO: Open of `wrk/SHETLAND_ISLANDS.NTF' using driver `UK .NTF' successful. 1: BL2000_LINK (Line String) 2: BL2000_POLY (None) 3: BL2000_COLLECTIONS (None) 4: FEATURE_CLASSES (None)
Example using an attribute query is used to restrict the output of the features in a layer:
% ogrinfo -ro -where 'GLOBAL_LINK_ID=185878' wrk/SHETLAND_ISLANDS.NTF BL2000_LINK INFO: Open of `wrk/SHETLAND_ISLANDS.NTF' using driver `UK .NTF' successful.
