DESCRIPTION ^

Will alter the BUFR messages in <bufr file> according to what is specified by the options provided. The modified file (text surrounding the BUFR messages will not be affected) will be printed to STDOUT (unless --outfile is set).

Execute without arguments for Usage, with option --help for some additional info.

OPTIONS ^

   --data <descriptor=value[+]> Set (first) data value in section 4 for
                    descriptor. A trailing '+' means that the value
                    should be added to existing value. Use 'missing'
                    to set a missing value. Repeat the option if more
                    sequence descriptors are to be set. Example:
                    --data 004004=-1+ --data 00405=50 --data
                    012101=missing This will set the data value for
                    first (and only first!) occurrence of these 3
                    descriptors in every subset and every message in
                    <bufr file> to the given value (subtracting 1 from
                    the existing value for 004004)
   --bufr_edition <value> Set BUFR edition to <value>. If the new edition
                    involves some metadata not present in the old edition,
                    some educated guesses for these new metadata are made,
                    but you should also consider setting these new metadata
                    explicitely
   --centre <value> Set originating centre to <value>
   --subcentre <value>
                    Set originating subcentre to <value>
   --update_number <value>
                    Set update sequence number to <value>. Use the special
                    value -1 to increment existing update sequence number,
                    -2 to decrement it
   --category <value> Set data category to <value>
   --subcategory <value> Set data sub-category to <value>
   --int_subcategory <value> Set international data sub-category to <value>
   --loc_subcategory <value> Set local data sub-category to <value>
   --master_table_version <value>
                    Set master table version number to <value>
   --local_table_version <value>
                    Set local table version number to <value>
   --<time_var> <value> Set <time_var> (= year | year_of_century | month |
                    day | hour | minute | second) in section 1 to <value>
   --observed 0|1   Set observed data in section 3 to 0 or 1
   --compress 0|1   Set compression in section 3 to 0 or 1
   --remove_sec2    Remove optional section 2 if present
   --remove_qc      Remove all quality control information,
                    i.e. remove all descriptors from 222000 on
   --outfile <filename>
                    Will print to <filename> instead of STDOUT
   --strict_checking n   n=0 (default) Disable strict checking of BUFR format
                         n=1 Issue warning if (recoverable) error in
                             BUFR format
                         n=2 Croak if (recoverable) error in BUFR format.
                             Nothing more in this message will be
                             decoded/encoded.
   --tablepath <path to BUFR tables>
                    Set path to BUFR tables (overrides $ENV{BUFR_TABLES})
   --verbose n      Set verbose level to n, 0<=n<=6 (default 0). Verbose
                    output is sent to STDOUT, so ought to be combined with
                    option --outfile
   --help           Display Usage and explain the options used. Almost
                    the same as consulting perldoc bufralter.pl

Options may be abbreviated, e.g. --he or -he for --help.

To avoid having to use the --tablepath option, you are adviced to set the environment variable BUFR_TABLES to the directory where your BUFR tables are located (unless the default path provided by bufralter.pl works for you).
