[gdal-dev] Combining shape files

[Rainer M Krug]

Hi

I have 6 shape files, named
region_SPP_1__Acacia_cyclops.shp to region_SPP_6__Acacia_cyclops.shp
which I would like to combinr into a single shape file, called
Acacia_cyclops.shp

For this I wrote the following script:

#!/bin/bash
SP="Acacia_cyclops"
ogr2ogr -f \"ESRI Shapefile\" "./comb/"$SP".shp" "./region_SPP_1__"$SP".shp"

ogr2ogr -update -append -f \"ESRI Shapefile\" "./comb/"$SP".shp"
"./region_SPP_2__"$SP".shp"
ogr2ogr -update -append -f \"ESRI Shapefile\" "./comb/"$SP".shp"
"./region_SPP_3__"$SP".shp"
ogr2ogr -update -append -f \"ESRI Shapefile\" "./comb/"$SP".shp"
"./region_SPP_4__"$SP".shp"
ogr2ogr -update -append -f \"ESRI Shapefile\" "./comb/"$SP".shp"
"./region_SPP_5__"$SP".shp"
ogr2ogr -update -append -f \"ESRI Shapefile\" "./comb/"$SP".shp"
"./region_SPP_6__"$SP".shp"

but even at line 3 I have problems:

if I do the following

> SP="Acacia_cyclops"
> ogr2ogr -f \"ESRI Shapefile\" "./comb/"$SP".shp" "./region_SPP_1__"$SP".shp"

I get the error message: "Unable to open datasource
`./comb/Acacia_cyclops.shp' with the following drivers."

but when I say
> echo ogr2ogr -f \"ESRI Shapefile\" "./comb/"$SP".shp" "./region_SPP_1__"$SP".shp"

and paste the output into the commandline, it works.

But with the remaining ogr2ogr, I have less luck: all result in the
same error message "Unable to open datasource
`./comb/Acacia_cyclops.shp' with the following drivers."

Any help appreciated,

Rainer
