NAME
dbamsg - Work with encoded meteorological dataSYNOPSIS
dbamsg [command] [options] [args...]DESCRIPTION
Examine, dump and convert files containing meteorological data. It supports observations encoded in BUFR, CREX and AOF formats.dbamsg always requires a non-switch argument, that indicates what is the operation that should be performed:
- help
Print a help summary.- help manpage
Print this manpage.- scan [options] filename [filename [...]]
Summarise the contents of a file with meteorological data.- dump [options] filename [filename [...]]
Dump the contents of a file with meteorological data.- cat [options] filename [filename [...]]
Dump the raw data of a file with meteorological data.- convert [options] filename [filename [...]]
Convert meteorological data between different formats.- compare [options] filename1 [filename2]
Compare two files with meteorological data.- filter [options] [queryparm1=val1 [queryparm2=val2 [...]]] filename1 [filename2...]
Copy only those messages whose contents match the given query parameters. The query can be done using the same parameters as dbadb or the Fortran DB-ALLe API. Only the parameters starting with lat, lon, year, month, day, hour, minu, sec are actually used for filtering..- fixaof [options] filename [filename1 [...]]]
Recomputes the start and end of observation period in the headers of the given AOF files.- makebufr [options] filename [filename1 [...]]]
Read a simple description of a BUFR file and output the BUFR file.. Read a simple description of a BUFR file and output the BUFR file. This only works for simple BUFR messages without attributes encoded with data present bitmaps.- bisect [options] --test=testscript filename
Bisect filename and output the minimum subsequence found for which testscript fails.. Run testscript passing parts of filename on its stdin and checking the return code. Then divide the input in half and try on each half. Keep going until testscript does not fail in any portion of the file. Output to stdout the smallest portion for which testscript fails. This is useful to isolate the few messages in a file that cause problems.- head [options] filename [filename [...]]
Dump the contents of the header of a file with meteorological data.
OPTIONS
dbamsg follows the usual GNU command line syntax, with long options starting with two dashes (`-').Options used to filter messages
- --category=num
- match messages with the given data category
- --subcategory=num
- match BUFR messages with the given data subcategory
- --check-digit=num
- match CREX messages with check digit (if 1) or without check digit (if 0)
- --unparsable
- match only messages that cannot be parsed
- --parsable
- match only messages that can be parsed
- --index=expr
- match messages with the index in the given range (ex.: 1-5,9,22-30)
