bitcoin-cli Network Commands
This section describes how to use 'bitcoin-cli getclock' command.
Once I have my Bitcoin Core Daemon running on the Bitcoin test network, the most important commands to learn are "bitcoin-cli" network commands which allows you see the Bitcoin network and control your connection to the network.
1. Run Bitcoin Core Daemon on the test network in a command window.
C:\>\local\bitcoin-0.15.1\bin\bitcoind -testnet
2. Run Bitcoin Core CLI in another command window and check the uptime:
C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli -testnet uptime 178913
3. Get the height of the blockchain maintained by the network.
C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli -testnet getchaintips
[
{
"height": 1029998,
"hash": "00000000000121674d133d45b91941c6168b4c19d32f529432a4c184174d0b86",
"branchlen": 1029998,
"status": "headers-only"
},
{
"height": 0,
"hash": "000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943",
"branchlen": 0,
"status": "active"
}
]
4. Get the number of blocks that have been synchronized on my local Bitcoin Core Daemon so far.
C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli -testnet getblockcount 119723 C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli -testnet getblockcount 124188
5. Get the number of peers that I am currently connected to:
C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli -testnet getconnectioncount 5
6. Get connection details with my peers.
C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli -testnet getpeerinfo

"bytessent": 2046,

"conntime": 1518359086,
...
},
...
]
7. Stop connections to the network. I can resume it later with "setnetworkactive true".
C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli -testnet setnetworkactive false false
