watch subscribed events to your xrpl node from the command line

websocat_subscribe_jq_process.sh

#!/bin/bash

# install websocat
# cargo install --features=ssl websocat
# --features=ssl needs to be included to connect to wss://

# we use `<<<` to send a string into the command:
#    echo '{"command"...}' | websocatt ...
# is equivalent

# use websocat to call the admin port
websocat ws://localhost:6006 -n \
    <<< '{"command":"subscribe","streams":["ledger"]}' \
    | jq '{txn_count,ledger_index,ledger_hash}'

# use websocat to call the default public port, if enabled, with self-signed cert (default with installation)
websocat -k wss://localhost:6006 -n \
    <<< '{"command":"subscribe","streams":["ledger"]}' \
    | jq '{txn_count,ledger_index,ledger_hash}'


# when you have the cert in the machine, such as the CA that signed xrplcluster.com, drop `-k`
websocat wss://xrplcluster.com -n \
    <<< '{"command":"subscribe","streams":["ledger"]}' \
    | jq '{txn_count,ledger_index,ledger_hash}'
