|---|
| [0b00607] | 3 | ********************************** |
|---|
| 4 | |
|---|
| [f20342a] | 5 | The execution of ``flex_extract`` is done by the ``run.sh`` shell script, which is a wrapper script for the top-level Python script ``submit.py``. |
|---|
| [0b00607] | 6 | The Python script constitutes the entry point to ECMWF data retrievals with ``flex_extract`` and controls the program flow. |
|---|
| 7 | |
|---|
| [f20342a] | 8 | ``submit.py`` has two (or three) sources for input parameters with information about program flow and ECMWF data selection, the so-called ``CONTROL`` file, |
|---|
| 9 | the command line parameters, and the so-called ``ECMWF_ENV`` file. Command line parameters will override parameters specified in the ``CONTROL`` file. |
|---|
| [0b00607] | 10 | |
|---|
| [f20342a] | 11 | Based on this input information, ``flex_extract`` applies one of the application modes to either retrieve the ECMWF data via a web API on a local maschine, or submit a job script to an ECMWF server and retrieve the data there, and at the end sends the files to the local system. |

| [f20342a] | 41 | It is also possible to start ``flex_extract`` directly from command line by using the ``submit.py`` script instead of the wrapper shell script ``run.sh``. This top-level script is located in |
|---|
| 42 | ``flex_extract_vX.X/Source/Python`` and is executable. With the ``--help`` parameter |
|---|
| 43 | we see again all possible command line parameters. |
