getutxid - Linux

Overview

getutxid is a Linux command that retrieves the unique transaction identifier (UTXID) for a given transaction in the database. UTXIDs are globally unique identifiers for each transaction, making them useful for tracking the history and dependencies of changes within the database.

Syntax

getutxid [options] [<transaction-id>]

Required Arguments

  • <transaction-id>: The ID or name of the transaction for which to retrieve the UTXID.

Options

  • -v, --verbose: Enable verbose output, displaying more information about the transaction and its UTXID.
  • -h, --help: Display a brief help message and exit.

Examples

Simple Example

Retrieve the UTXID for the latest transaction:

getutxid

Retrieving UTXID for a Specific Transaction

Specify the transaction ID or name to retrieve its UTXID:

getutxid <transaction-id>

Verbose Output

Enable verbose mode to display additional details about the transaction:

getutxid -v <transaction-id>

Common Issues

Transaction Not Found

If the specified transaction ID or name does not exist, getutxid will return an error message. Ensure that the transaction has been committed successfully before attempting to retrieve its UTXID.

Integration

Combining with Other Commands

getutxid can be combined with other commands to analyze transaction history and dependencies:

getutxid | grep <pattern>

Database Management Scripts

getutxid can be incorporated into database management scripts to automate monitoring and troubleshooting tasks:

#!/bin/bash

# Retrieve the UTXID for the last transaction
utxid=$(getutxid)

# Log the UTXID for future reference
echo "Last transaction UTXID: $utxid" >> /var/log/db.log
