 You should be able to run all configuration file examples without changing contained options. However, configurations 'Upload.bnc' and 'UploadPPP.bnc' are exceptions because they require an input stream from a connected network engine.

 The following configuration examples make use of BNC's 'Command Line Interface' (CLI). Configuration options are exclusively specified via command line. No configuration file is used. Examples are provided as shell scripts for a Linux system. They call BNC in 'no window' batch mode (command line option -nw). The scripts expect 'Example_Configs' to be the current working directory.

+<b>(C) Command Line configuration options overwriting Configuration File options</b><br><br>
+For specific applications you may like to use your own set of standard configuration options from a configuration file and update some of its content via command line.

+Purpose: Equals configuration file example 'CompareSp3.bnc', compares two SP3 files to calculate RMS values for orbit and clock differences. However, instead of excluding GPS satellite G05 and GLONASS satellite R18 from the comparison as specified in 'CompareSp3.bnc', GPS satellite G06 and all GLONASS satellites are excluded via command line option. Comparison results are saved in a logfile.
