Block Meta Data

Question

Is there a way to get block meta data only. For example:

cleos get block 12345

returns all transactions within that block. All I am interested in is the metadata. Is there a way to return without transaction data, for example:

"timestamp": "2018-11-26T18:52:45.500"

"producer": "eosio"

"confirmed": 0

"previous": "00083482841cd88ca17ff610158ea48cc9c281aaca6a0c51e5c2bd4c9ef94ccd"

"id": "00083483ebdf2141ae15cd69208f7cc6dbae250f234cf38bf8e1ecb0a0398f33"

"block_num": 537731

"ref_block_prefix": 1775048110

Specifically, I only want:

• block_num
• timestamp
• confirmed

You can specify how many of the first lines you want in terminal with | head -n 11 then for the last 5 you can add | tail -n 5. This will effectively skip the transaction section.

./cleos -u https://nodes.get-scatter.com:443 get block 29000000 | head -n 11

{
  "timestamp": "2018-07-09T15:41:24.000",
  "producer": "eosswedenorg",
  "confirmed": 240,
  "previous": "004c4b3ff0edbaaf4f3ab1149a9baaf0b8edb97b02e41975f9e2489a6907ff6a",
