'''Coreutils''' is a package of [[GNU]] [[software]] containing many of the basic tools such as [[cat ((command))|cat]], [[ls]], and [[rm ((command))|rm]] needed for Unix-like operating systems.

== GNU coreutils capabilities ==

The GNU core utilities support long options as parameters to the commands, as well as the relaxation of the convention of specifying options before the regular arguments, unless the <tt>POSIXLY_CORRECT</tt> environment variable is set. Additionally, as the GNU philosophy shifts information away from manual pages (and uses tools such as <tt>[[texinfo|info]]</tt>), usage information is more extensive.
