uniq Ref geliştiren: Libor Benes (Dr. B)

uniq Ref is a lightweight Firefox sidebar extension offering efficient offline access to 91 essential uniq command options, filtering patterns, and practical usage scenarios for detecting and handling duplicate lines in text.

The uniq command, written by Ken Thompson for Unix, appeared in Version 3 Unix (February 1973) and has remained a cornerstone of text processing ever since. It reports or filters out repeated lines in adjacent positions within sorted input, making it indispensable for data deduplication, frequency analysis, and log file processing. uniq embodies the Unix philosophy of focused tools that excel at specific tasks when combined with other utilities like sort.
