Keep Lines Containing Text
Keep only the lines that match a word, phrase or pattern.
Keeps only the lines that match, discarding everything else — the equivalent of grep. An empty search term is treated as a no-op rather than a match-everything, so clearing the field restores your text instead of wiping it.
Options
Every test has a “does not” form. An empty search term is still a no-op either way.
Match cat but not cats or concatenate.
Blank lines are never discarded even if they do not match.
