Template FAQ

What is the simplest sed command to delete TRACE log lines?

A common starting point is `sed '/TRACE/d'`, which removes every row containing the TRACE marker. It is useful when logs are too verbose and you want to remove low-level noise fast.

Why use delete-trace-lines if delete-debug-lines already exists?

TRACE and DEBUG often represent different verbosity levels. A dedicated delete-trace-lines page matches the exact search phrase developers use when they only want to cut trace-level noise.
