Added searching of zip archive files with option -z, supporting zip methods stored and deflate, and optionally bzip2, lzma, and xz if libbzip2 and liblzma are installed. Option -z also searches cpio, tar, and pax archives compressed in zip files, displaying matches as archive.zip{archive.tar:matchedfile} when matchedfile is found in archive.tar when compressed and stored in archive.zip. Options -g GLOB, -t TYPES, -O EXTENSIONS, and -M MAGIC can be used to filter and search files in cpio, tar, pax, and zip archives.
