Ivan,

For example with

$ ogrinfo -ro ../autotest/ogr/data/curves.gdb -sql "GetLayerDefinition polygon"
INFO: Open of `../autotest/ogr/data/curves.gdb'
      using driver `OpenFileGDB' successful.

Layer name: LayerDefinition
Geometry: Unknown (any)
Feature Count: 1
Layer SRS WKT:
(unknown)
FIELD_1: String (0.0)
