OPTIONS
...
Declaration of keys to print. For each key a string (key:s) or , a double (key:d) or a long an integer (key:li) type can be requested. Default type is string.
...
C style format for floating-point values.
...
As -p adding the declared keys to the default list.
...
Where clause. Messages are processed only if they match all the key/value constraints. A valid constraint is of type key=value or key!=value. For each key a string (key:s) or , a double (key:d) or a long an integer (key:li) type can be specified. Default type is string.
...
Order by. The output will be ordered according to the order by directive. Order by example: "step asc, centre desc" (step ascending and centre descending) In the value you can also use the forward-slash character '/' to specify an OR condition (i.e. a logical disjunction) Note: only one -w clause is allowed.

bufr_ls examples
Without options a default list of keys is printed. The default list can be different depending on the type of bufr BUFR message.
The result is:Code Block > bufr_ls ../data/bufr/syno_*multi.bufr
To print offset and count number in file use the keys offset and count. Also the total count in aCode Block ../data/bufr/syno_1multi.bufr masterTablesVersionNumber centre localTablesVersionNumber rdbType rdbSubtype rdbtimeYear rdbtimeMonth masterTablesVersionNumber localTablesVersionNumber typicalDate typicalTime numberOfSubsetsrdbType localLatitude rdbSubtype localLongitude rdbtimeDate 13 rdbtimeTime 1 numberOfSubsets localLatitude 1 localLongitude ecmf 1 2012 10 20121030 000000 1 7.45 151.83 1 of 1 messages in ../data/bufr/syno_1.bufr ../data/bufr/syno_2.bufr 13 1 120090124 1 2012 10 20121030 120000 000000 1 7.45 151.83 1 of 1 messages in ../data/bufr/syno_2.bufr ../data/bufr/syno_3.bufr 13 20090124 1 1 3 2012 121435 10 20121030 000000 1 -1570.93 -58.67 1 of 1 messages in ../data/bufr/syno_3.bufr ../data/bufr/syno_4.bufr 13ecmf 1 13 1 120090124 2012 10 20121030 120000 000000 1 54.18 7.9 1 of 1 messages in ../data/bufr/syno_4.bufr ../data/bufr/syno_multi.bufr 13 20090124 1 1 121435 1 200977 1 20090124 120000 1 70.93 15.5 -8.67 13 ecmf 1 1 1 13 2009 1 20090124 120000 1 77 15.5 13 1 1 1 2009 1 20090124 120000121435 1 78.92 11.93 3 of 3 messages in ../data/bufr/syno_multi.bufr 73 of 73 total messages in 51 files

To list only a specific set of keys use the -p option.
Code Block > bufr_ls -p totalLength,bufrHeaderCentre,bufrHeaderSubCentre ../data/bufr/syno_multi.bufr 7 of 7 total messages in 5 files
To list only a subset of messages use the -w (where option). Only the SYNOP 12 UTC messages are listed with the following line.
Code Block > bufr_ls -W 8 -w dataCategorytypicalTime=0"120000" ../data/bufr/syno_*.bufr ../data/bufr/temp_*.bufr
All the non-SYNOP 12 UTC messages are listed as follows:
Code Block > bufr_ls -W 8 -w dataCategorytypicalTime!=0"120000" ../data/bufr/syno_*.bufr
To list only the second message from a BUFR file:
Code Block > bufr_ls -w count=2 ../data/bufr/tempsyno_*multi.bufr
