+gnu-utility
+===========
+
+Provides for the interactive use of [GNU Core Utilities][1] on non-GNU systems.
+
+Installing the GNU Core Utilities on non-GNU systems in `$PATH` without
+a prefix, i.e. `ls` instead of `gls`, is not recommended since scripts that
+target other core utilities will be broken.
+
+However, for interactive use, prefixed commands can be hashed to their
+non-prefixed counterparts.
+
+Settings
+--------
+
+### Prefix
+
+To use a different prefix, add the following to *zshrc*, and replace 'g' with
+the desired prefix:
+
+    zstyle ':omz:module:gnu-utility' prefix 'g'
