1. Without options a default list of keys is printed. The default list is can be different depending on the type of bufr BUFR message.

   Code Block
   > bufr_ls ../data/bufr/syno_*multi.bufr

   The result is:

   Code Block

   To print offset and count number in file use the keys offset and count. Also the total count in a




2. It is allowed to use wildcards in filenames. set of files is available as countTotal

   Code Block
   > > bufr_ls -p offset,count,countTotal ../data/bufr/syno_*.bufr ../data/bufr/syno_1.bufr offset count countTotal 0 1 1 1 of 1 messages in ../data/bufr/syno_1.bufr ../data/bufr/syno_2.bufr 0 2 2 1 of 1 messages in ../data/bufr/syno_2.bufr ../data/bufr/syno_3.bufr 0 3 3 1 of 1 messages in ../data/bufr/syno_3.bufr




3. To list only a specific set of keys use the -p option.

   Code Block
   > bufr_ls -p totalLength,bufrHeaderCentre,bufrHeaderSubCentre ../data/bufr/syno_4.bufr 0 4 4 1 of 1 messages in ../data/bufr/syno_4.bufr ../data/bufr/syno_multi.bufr 0 5 5 220 6 6 440 7 7 3 of 3 messages in ../data/bufr/syno_multi.bufr 7 of 7 total messages in 5 files




4. 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




5. 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




6. To list only the second message from a BUFR file:

   Code Block
   > bufr_ls -w count=2 ../data/bufr/tempsyno_*multi.bufr
