fltr is a minimal, dependency-free filtering utility written in C, inspired by UNIX philosophy and designed for high-performance data stream filtering. It allows users to apply pattern-based rules to lines of input—much like grep or awk—but with a focus on simplicity, low overhead, and customizability. It's intended for those who need a small, efficient tool to clean, parse, or analyze large streams of textual data on the command line without complex scripting or configuration.
