# You can run the transfer script to create operations for this script to find.
# The script is set for looking back 50 blocks. 8 second blocks means 400 seconds, or 6.5 minutes of history.
# This script fetches and prints the transaction history for a specific Tezos address by checking the last 100 blocks.
# The `-n` test checks if the `transactions` variable is non-empty, which would indicate that transactions were found.
# If transactions were found, the script prints the level and the transactions
# The `transaction_levels+=($level)` line adds the current level to the `transaction_levels` list each time transactions are found.
# After the loop is done, the script prints the list of levels where transactions were found.
# The `transaction_metadata[$level]=$transactions` line adds the transaction metadata to the `transaction_metadata` associative array keyed by the level.
# After the loop is done, the script loops over the `transaction_levels` list and prints the transaction metadata for each level.
