DESCRIPTION
7z is the command-line interface to the 7-Zip archiver, supporting many formats: 7z, ZIP, TAR, GZIP, BZIP2, XZ, and more.The 7z format offers high compression ratios using LZMA/LZMA2 algorithms, often 30-70% better than ZIP. It also supports AES-256 encryption and multi-volume archives.Extraction supports many additional formats including RAR, CAB, ISO, and others (read-only for some formats).

CAVEATS
The 7z format is not as universally supported as ZIP. Consider ZIP for maximum compatibility.-o has no space: -o/path not -o /path.RAR creation requires separate RAR tools. 7z can only extract RAR files.Split archives (-v) require all volumes for extraction.
