I'd like to compress one huge file (~200GB) from the command line. no need for archiving its directory along with it, swift operation and high compression ratio preferred. What may be some good ways?
I would recommend to use 7z.
7Z is 7-Zip's archiving format, providing high compression ratio through powerful compression algorithms that can take benefit of parallel computing on modern multicore CPUs.
To make 7z archive you need p7zip-full package. To make archive run
7z a <you_archive_name>.7z <filename>
