NAME
dbamsg - Work with encoded meteorological data
SYNOPSIS
dbamsg [command] [options] [args...]
DESCRIPTION
Examine, dump and convert files containing meteorological data. It supports observations
encoded in BUFR or CREX 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] [filter] filename [filename [...]]
Summarise the contents of a file with meteorological data.
head [options] [filter] filename [filename [...]]
Dump the contents of the header of a file with meteorological data.
dump [options] [filter] filename [filename [...]]
Dump the contents of a file with meteorological data.
cat [options] [filter] filename [filename [...]]
Dump the raw data of a file with meteorological data.
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.
convert [options] [filter] filename [filename [...]]
Convert meteorological data between different formats.
compare [options] filename1 [filename2]
Compare two files with meteorological data.
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.
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)

EXAMPLES
Here are some example invocations of \fBdbamsg\fP:
# Convert a BUFR message to CREX
dbamsg convert file.bufr -d crex > file.crex
# Convert BUFR messages to CREX, but skip all those not in january 2010
dbamsg convert year=2010 month=1 file.bufr -d crex > file.crex
# Dump the content of a message, as they are in the message
dbamsg dump file.bufr
# Dump the content of a message, interpreted as physical quantities
dbamsg dump --interpreted file.bufr
