logpr

logpr is a command-line utility designed for processing and analyzing log files. It allows users to filter, search, and manipulate log data in various ways, making it a valuable tool for system administrators, developers, and anyone working with application or system logs. The primary function of logpr is to provide a more efficient and structured approach to examining the often voluminous output of log files compared to simply using standard text manipulation tools.

The utility supports a range of operations. Users can specify criteria to select specific log entries, such as filtering by timestamps, keywords, severity levels (e.g., error, warning, info), or specific process IDs. Beyond simple filtering, logpr can also perform aggregations, allowing for the summarization of log data, such as counting the occurrences of specific events or calculating time differences between log entries. Its capabilities extend to transforming log data, enabling users to reformat entries or extract specific pieces of information for further analysis or integration with other tools. The syntax of logpr is designed to be flexible, often employing a pattern-matching approach for defining search and filter conditions. This makes it adaptable to a wide variety of log file formats and structures.
