uniqs – alternative to uniq

uniqs is a Rust command-line utility that serves as an alternative to uniq with streaming support.

It’s intended for text-processing workflows where you want to remove repeated lines as data is read, without relying on a prior sort step, making it a good fit for pipelines and larger input streams.

This is free and open source software.

Key Features

  • Reads from standard input by default, with optional input and output file arguments.
  • Writes each distinct line once, ignoring lines that have already appeared earlier in the input.
  • Includes a --count option to prefix lines with their number of occurrences.
  • Supports use in shell pipelines as well as direct file-to-file processing.
  • Provides a completion subcommand to generate shell completion scripts.
