Bring the full power of the Unix terminal command-line (`grep`, `sort`, `uniq`, `head`, `tail`) directly into your web browser without installing WSL, Cygwin, or Linux.
Tool Suite Features: ⢠Regex Grep Filter: Pattern matching with case-insensitive (-i), invert match (-v), and line number (-n) support. ⢠Sorting & Deduplication: Natural numerical sort (sort -n), alphabetical, line length ordering, and unique line deduplication (sort -u). ⢠Head & Tail Slicing: Extract the first N lines (head -n) or last N lines (tail -n) of multi-thousand-line log dumps. ⢠Regex Entity Extractor: Automatically mine and extract every Email address, Web URL, IPv4 address, or numeric value into a clean list. ⢠Real-Time Telemetry: Track input lines, filtered lines, and percentage retention in real time.

Frequently Asked Questions
Can I use full Regular Expressions in the Grep mode?
Yes! Enable the RegEx Engine toggle to use standard JavaScript regular expressions with flags and capture groups.
How does natural numerical sorting work?
Unlike standard alphabetical sort (which orders 1, 10, 2), natural numerical sort understands numerical values and correctly orders 1, 2, 10.
Can I extract all email addresses from messy text?
Yes! Switch to Extract Entities and choose Emails to instantly extract all RFC-compliant email addresses into a deduplicated list.
