`lipo` command available in `macOS` that creates or operates on multi-architecture files.

lipo command available in macOS creates or operates on multi-architecture files. It only ever produces one output file, and never alters the input file. The operations that lipo performs are: listing the architecture types in a universal file; creating a single universal file from one or more input files; thinning out a single universal file to one specified architecture type; and extracting, replacing, and/or removing architectures types from the input file to create a single new universal output file.
