Command-line scripts¶

Two command-line scripts will be created by python setup.py install.

Both print the available options with description for each option to STDOUT:

trollbufr -h
trollbufr --help

trollbufr_update -h
trollbufr_update --help

Executing them without any command-line option, they will just print the list of options to STDOUT.

trollbufr¶

This is a command-line script to call bufr_main.py.

Reading data elements:
```
trollbufr -t tables -d data/mw/TestBulletin_051
```
Decoding all BUFR in the file TestBulletin_051, for each reading the data elements and writing the descriptor, short name, value, unit to STDOUT. The table format defaults to “eccodes”.
```
trollbufr -t tables -o Test.txt -d data/mw/TestBulletin_051
```
Does the same as the first example, but writes to the file Test.txt.
Simple list of descriptors:
```
trollbufr -t tables -T libdwd -smb 1 data/mw/TestBulletin_051
```
Using the table-format libdwd and decoding only the first BUFR in the file, writing the un-expanded list of descriptors (without names, etc.) to STDOUT.
Encoding data from a JSON-formatted file as BUFR:
```
trollbufr -t tables -e -o Test.bin data/TestBulletin_1.json
```
Encodes the JSON-formatted content of the file TestBulletin_1.json and writes the resulting BUFR to the file Test.bin instead of STDOUT.

A command-line script to download archive file(s) from Internet resources in order to update the BUFR table files.

URL(s) on command-line, strip first two elements from path on extract:

trollbufr_update -t tables -s 2 -U https://opendata.dwd.de/weather/lib/bufr/bufrtables_libdwd.tar.bz2

Set of URLs in a file – only download, no extract:

trollbufr_update -t tables --download -F bufr_table_archives.txt
