Compressing

• Very useful for shrinking huge files and saving space

• g[un]zip <file> GNU zip compression utility. Creates .gz files. Ordinary performance (similar to Zip).

• b[un]zip2 <file> More recent and effective compression utility. Creates .bz2 files. Usually 20-25% better than gzip.

• Using 7-zip Much better compression ratio than bzip2 (up to 10 to 20%). See the 7-zip page for details.
