auparse_next_field - Linux


auparse_next_field is a utility designed to parse records from AU format files. It efficiently extracts and returns the next field from the provided input. This command is useful for processing audit event data stored in AU format, allowing for efficient retrieval and interpretation of specific field values.


auparse_next_field [-f field_name] [-t time_format] [-i] [-l] [-q] [-h]


  • -f field_name (Optional): Specifies the field name to extract. If omitted, all field names are printed in a tabular format.
  • -t time_format (Optional): Sets the format for displaying timestamps. Defaults to "YYYY-MM-DD HH:MM:SS.SSSSSS".
  • -i (Optional): Ignores case when matching field names.
  • -l (Optional): Lists all available field names.
  • -q (Optional): Suppresses all output except for the extracted field value.
  • -h (Optional): Displays help information.


Example 1: Extract All Field Names

auparse_next_field -l

Example 2: Extract a Specific Field Value (Timestamp)

auparse_next_field -f timestamp

Example 3: Extract Field Value in Custom Time Format

auparse_next_field -f timestamp -t "MM-DD-YY HH:MM:SS"

Common Issues

Missing Field Name: If no field name is specified, all field names are printed, and no field value is extracted.


auparse_next_field can be integrated with other tools or scripts for advanced processing tasks. For example, it can be used to extract specific field values from multiple AU files and save them in a structured format for further analysis.
