How to run RocksDB ldb tool

ldb tools reside in rocksdb directory. The location can be anywhere where the user built the rocksdb into. I built mine from home directory. 

rocks@ubuntu:~/rocksdb$ pwd; ls -las ldb

/home/rocks/rocksdb

110692 -rwxrwxr-x 1 rocks rocks 113342424 Mar 15 15:44 ldb

 

./ldb --db=/home/rocks/builds/p2-blockchain/release/Blockchain/EthereumBlockchain/scripts/dbtest2 scan

Step 2b: If the data type is Block data type use '--hex' flag.

./ldb --db=/home/rocks/builds/p2-blockchain/release/Blockchain/EthereumBlockchain/scripts/dbtest2 scan --hex |less

./ldb --db=/home/rocks/builds/p2-blockchain/release/Blockchain/EthereumBlockchain/scripts/dbtest2 scan --hex > output.dat

rocks@ubuntu:~/rocksdb$ ./ldb --db=/home/rocks/builds/p2-blockchain/relwithdebug/Blockchain/EthereumBlockchain/scripts/dbtest1 scan --hex
