Ultra fast grep with interactive query TUI, Boolean search, fuzzy search, and more: search file systems, Unicode text files (UTF-8/16/32), binary files to view hexdumps, source code, (nested) archives (cpio/tar/pax/zip), compressed files (zip/gz/Z/bz2/xz/lzma/lz4/zstd), documents and more. Search for anything in everything... fast!

Spontaneous compliments and kudos

"Ugrep belongs on every computer. It replaces and complements the standard commands quite excellently, and anyone who has to deal with text searches should familiarize themselves with it. The incremental search alone is so useful that it more than justifies the minimal training time." - Linux Magazine April 2021
