Can I check the compression algorithm of a compressed file if it was compressed with gzip -9 ?
Try 'file'. If the output does not mention any compression method, the file was compressed with DEFLATE:
$ file libpng-1.6.37.tar.gzlibpng-1.6.37.tar.gz: gzip compressed data, was "libpng-1.6.37.tar", from Unix, last modified: Sun Apr 14 20:10:32 2019, max compression
