Hi Mncedi,

Welcome to GDAL !

Here is how I recommend working through that (using a working example) :

Step 1:  ogrinfo
----------------

Always always start with an ogrinfo command, to see the available layer 
names:

	ogrinfo WFS:https://demo.gatewaygeomatics.com/cgi-bin/wfs_gateway


	returns:

		using driver `WFS' successful.
		1: ms:park

Great! We now know the layer name is called "ms:park"

Step 2: ogrinfo + layername
---------------------------

Next, see if ogrinfo can return info about that ms:park layer:

	ogrinfo WFS:https://demo.gatewaygeomatics.com/cgi-bin/wfs_gateway 
ms:park -summary

	returns:

		using driver `WFS' successful.
		Layer name: ms:park
			Metadata:
   				TITLE=Parks
				Geometry: Unknown (any)
				Feature Count: 46
				Extent: (-2346804.000000, -67422.421875) - (2840366.000000, 
3830124.250000)
				Layer SRS WKT:
				PROJCS["NAD83 / Canada Atlas Lambert"

Great! ogrinfo gave us info about our layer

Step 3: ogr2ogr + layername
---------------------------

Notice that the syntax is something like:  ogr2ogr output input layername :

	ogr2ogr -f "ESRI Shapefile" parks.shp 
WFS:https://demo.gatewaygeomatics.com/cgi-bin/wfs_gateway ms:park



Tested using MS4W 4.0 https://ms4w.com
