Getting only the last N lines of text usually means opening a file or using the tail command. The Tail Text tool does it in the browser: paste your text, enter N, and get the last N lines—no sign-up and no data sent to a server.
What does Tail Text do?
Tail Text is a free online tool that returns the last N lines of your text, like the Unix tail command. It is useful for viewing the end of logs or lists, seeing the most recent entries, or checking the end of a long file. All processing runs in your browser; there is no upload, no storage, and no account required.
Key Features
- Last N lines — Enter N (e.g. 10); you get the last N lines. If the input has fewer than N lines, you see all of them.
- Line-based — Lines are counted from the bottom. Any line ending (LF or CRLF) is supported.
- Any input — Paste or type text with line breaks. No size limit for in-browser processing.
- Instant result — Paste, set N, and see the result. Copy when ready.
- Privacy-first — All processing happens in your browser. Your text is never sent to any server.
- No account — Use as often as you need without sign-up.
How to Use Tail Text
- Open the Tail Text tool.
- Paste or type your text (multi-line).
- Enter N (e.g. 10). View the last N lines. Copy the result.
- Paste into your doc or use for log review. Use the "Use tool" button on the docs page if you are reading this from the documentation.
Real Use Cases
- Most recent log entries — See the last 20 or 50 lines of a log. Great for recent errors or activity.
- Last N items in a list — Keep only the last N lines (e.g. last 5 results). Drop the rest.
- End of long file — Check the end of a pasted file without scrolling. Confirm footer or final section.
- Quick sample from end — Sample the end of pasted content (e.g. latest entries).
- Terminal-style workflow — When you do not have tail on the machine, use the browser tool.
- Debug and support — Share only the last N lines of a log for a ticket (most recent first).
Why Use Tail Text Instead of Alternatives?
- vs. Manual scroll — No need to scroll to the end and select. One paste, set N, copy.
- vs. Extract Line Range — For a range (e.g. lines 50–60) use Extract Line Range. For "last N" use Tail.
- vs. Head — Head Text gives the first N lines. Tail gives the last N.
- vs. Scripts — No coding. Works in any browser.
You get at most N lines from the end. If the input has fewer lines than N, you see all of them.
Benefits for Developers, Support, and Data Users
- Developers — Quick view of the end of log or output. No terminal or script needed.
- Support — Extract the most recent part of a log for troubleshooting.
- Data users — Sample the end of line-based data (e.g. latest rows).
Common Mistakes
- Fewer than N lines — You get at most N lines from the end. If the input has fewer lines than N, you see all of them.
- Expecting first N lines — This tool is last N. For first N use Head Text.
- Forgetting to copy — The result is not saved. Copy before closing the tab or refreshing.
