I'm assuming by this that you don't mean 'working with a sed script'.

Why use sed?  You've said you're using a script with sed in it, so why not use
something different.  On SysV and SunOS 4.0.3_EXPORT (therefore probably BSD
systems in general??) you can use _d_i_r_n_a_m_e to do exactly what you require.

Check out _b_a_s_e_n_a_m_e too.  Thus,

	% dirname '/aaa/bbb/ccc/ddd/eee'
	/aaa/bbb/ccc/ddd/eee
	% basename '/aaa/bbb/ccc/ddd/eee'
	eee
	%
