log parsing

Logs serve as a window into the operations of an application or system and are crucial for troubleshooting issues and optimizing performance. For system administrators and developers working on Linux, mastering log parsing and data extraction is essential. This article explores some effective techniques and tools you can use to parse logs and extract useful information on a Linux system. Log files in Linux are typically stored in the /var/log directory. Files located here can include system logs (syslog), authentication logs (auth.log), web server logs, and logs from various installed applications. Depending on the Linux distribution and the specific application, the exact naming and rotation scheme of log files may vary.
