Template FAQ
What is the simplest sed command to delete DEBUG log lines?
A common starting point is `sed '/DEBUG/d'`, which removes every row containing the DEBUG marker. This is a classic cleanup command for trimming noisy logs before review or sharing.
Why keep a dedicated delete-debug-lines page if delete-matching-lines already exists?
Because deleting DEBUG rows is a specific, high-intent search phrase that developers use directly. A dedicated page helps match that exact search need while still linking to broader filtering templates.
