Geoserver2.6. REST cURL automation to add GeoTIFFs (batch)

I would like to add and publish hundreds of GeoTIFFs to my GeoServer datastore. I have started to write a batch file to manage GeoServer by REST API. I have finally figured out how to create a new workspace and datastore. But do not know how to add hundreds of GeoTIFFs from a local folder. I have tried to use a loop and wildcards.I cannot figure it out.

For the following code I got the error message:

curl: no URL specified!
curl: try 'curl --help' for more information
uebung1.bat: line 28: http://loclahost:8080/geoserver/rest/workspaces/DPP/datastores/BarometricPressure: No such file or directory
mat80localhost 138 <.../TERENO_StationViewer/batch>:

Here is the batch-code:

#!/bin/bash
curl -u admin:geoserver -v -XGET -H 'Accept: text/xml'\
    "http://loclahost:8080/geoserver/rest/workspaces" 
echo ""

echo ""
curl -u admin:geoserver -v -XPOST -H 'Content-type: text/xml' \
     -d '<workspace><name>DDP</name></workspace>'\
     "http://localhost:8080/geoserver/rest/workspaces"

echo "----- Then create the datastore. ------------------------------------"
echo ""
