See the `dirname' and `basename' commands:

	$ dirname "/usr/local/scripts/"

	$ basename "/usr/local/scripts/"

Be careful about properly quoting the filenames though (note how the
first invocation of `dirname' fails below, and try to understand why
it fails):

	$ testname='foo bar baz'
	$ dirname $testname
	usage: dirname string
	$ dirname "${testname}"
