[Graham B]

Hi, I am Graham, living in Brisbane Australia. Certainly not an IT professional but I hope that ogr2ogr can help me do some basic edits to a large number of shapefiles.

I have a batch file as below (presently sitting in the FW tools\bin foldeer to eliminate any path issues while I get it working.

I am trying to update a shapefile called temp.shp

That is,  I want to open temp.shp and edit it such that only records where the field called FEAT_CODE = "sea" remain. Ideally I will update the original file but if ogr2ogr can create another shapefile called temp2.shp then that is OK too.

In the same folder I have the four components of the shapefile, i.e 

temp.shp
temp.prj
temp.dbf
temp.shx


If anyone can give me a couple of pointers to get me started I would really appreciate it.

Thanks in advance,
                             Graham B
