Text Line Editor

List-oriented text shows up in host inventories, feature flag exports, email recipient lists, and shell command output. Sorting, numbering, trimming whitespace, deduplicating, and dropping blank lines are routine cleanup steps before diffing or importing into spreadsheets.

Alphabetical line sort helps compare two server lists or dependency outputs. Line numbering gives reviewers stable references in tickets. Deduplication removes repeated API keys or URLs pasted from multiple sources, but preserves first-seen order unless you explicitly sort afterward.

Trim modes fix trailing spaces that break exact-match tests. Removing empty lines tightens diffs when generators emit double newlines between sections. Watch for lines that look empty but contain tabs or non-breaking spaces; trim does not always catch invisible Unicode.

Use line editors locally when lists include internal hostnames or customer identifiers. Browser processing keeps raw paste content off third-party text utilities during incident exports or access reviews.
