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.


   --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
   --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
   --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).
