The Free Software Foundation's "core" utilities, including "chgrp",
"chmod", "chown", "cp", "dd", "df", "dir", "dircolors", "du",
"install", "ln", "ls", "mkdir", "mkfifo", "mknod", "mv", "rm",
"rmdir", "shred", "sync", "touch", "vdir".

These utilities exist in the FreeBSD base collection, but the GNU
versions have added functionality that is sometimes useful.
