uniqtoo

A single binary replicating the behavior of sort | uniq -c | sort -nr with output that updates in real-time as each line is parsed.

Usage

Pipe something line-based into uniqtoo the same as you would into sort | uniq -c.

Here is an example counting the extensions of files in this repository with a 0.5s delay in between.

You can also supply the input as a file or file descriptor as an argument.

$ uniqtoo input.txt

Install

Rust / Cargo

$ cargo install uniqtoo

The binary will be placed in your ~/.cargo/bin which should be on your shell's $PATH.

Docker

A container with the binary is available from Docker Hub and GitHub Container Registry.

• jakewharton/uniqtoo
• ghcr.io/jakewharton/uniqtoo

Use docker run instead of directly using the binary.

input_command | docker run --rm -i -a STDIN -a STDOUT jakewharton/uniqtoo
