shopt -s dotglob	# With this set, the glob matches hidden files (".*") by default,
					# but not the . or .. links.
shopt -s globstar	# If set, the pattern "**" used in a pathname expansion context will
					# match all files and zero or more directories and subdirectories.
shopt -s extglob	# Enable additional globs. Resulting in what is effectively a Regex
							# language builtin to Bash.
