hist-rs is a Rust command-line utility built for high-throughput line-oriented text processing.
It provides a fast standalone alternative to traditional shell pipelines for building histograms of repeated lines, and it also includes extra controls for deduplication, filtering, substitutions, and output shaping that make it useful for logs, datasets, and other text streams.
This is free and open source software.
Key Features
- Counts the abundance of unique lines from files or standard input.
- Can output only unique lines to deduplicate an input stream.
- Supports include and exclude pattern matching while processing input.
- Filters results using minimum or maximum abundance thresholds.
- Can sort output by key or abundance in ascending or descending order.
- Supports regex-based pattern substitution on incoming lines.
- Can show the last k entries together with a summary count of the remaining data.
- Includes an option to generate a histogram without sorting by value.
