2.14 coreutils: Multi-call program
The coreutils command invokes an individual utility, either implicitly selected by the last component of the name used to invoke coreutils, or explicitly with the --coreutils-prog option. Synopsis:
coreutils --coreutils-prog=PROGRAM …
The coreutils command is not installed by default, so portable scripts should not rely on its existence.
