March 3 saw the release of version 7.3 fast cross-platform console text search utility ugrep.
For more efficient searching through a large number of files on slow storage, or when searching within many archives (zip, zstd, tar, bzip2, bzip3, 7z, lzma, lz4, brotli, etc.), you can first perform indexing using the ugrep-indexer utility (included with ugrep starting from version 6.0).
The utility is written in C++ and distributed under the BSD-3 license.
This release features usability improvements and fixes for the -i (—ignore-case) and -j (—smart-case) options. They now utilize their own Unicode case conversion functions, which are not part of ASCII. For example, echo "Śrem" | ug -i "ś.*" will now successfully find a match and print 1: Śrem, as the user expects.
