Hi Oliver,

 you can also use the ExecBinding.EXEC_COMMAND_ARGS header to set the 
command args dynamically.  The header value must be a List<String> with 
the args. 

You may even implement your own org.apache.camle.Expression that returns 
the list based on the Camel exhcange (e.g. based on Exchange.FILE_NAME).

Such Java DSL would look like:

...
.setHeader(ExecBinding.EXEC_COMMAND_ARGS , new YourArgsProviderExpression(
))

....
class YourArgsProviderExpression imlements org.apache.camle.Expression{
 ...
}


Hope this helps.

Regards, 
Mitko

Hi

You can use the recipient list pattern for such dynamic endpoints.
