GNU Core Utilities
The GNU Core Utilities or coreutils is a package of GNU software containing reimplementations for many of the basic tools, such as cat, ls, and rm, used on Unix-like operating systems. It is a combination of a number of earlier packages, including textutils, shellutils, and fileutils, along with some other miscellaneous utilities.
GNU coreutils capabilities
The GNU core utilities support long options as parameters to the commands, as well as (unless the POSIXLY_CORRECT environment variable is set) the relaxed convention allowing options even after the regular arguments. Note that this environment variable enables a different functionality in BSD.
