_bbbb_aaaa_ssss_eeee_nnnn_aaaa_mmmm_eeee deletes any prefix ending in _//// and the _s_u_f_f_i_x (if present in
_s_t_r_i_n_g) from _s_t_r_i_n_g, and prints the result on the standard output. It is
normally used inside substitution marks (_````_````) within shell procedures.
The _s_u_f_f_i_x is a pattern as defined on the _eeee_dddd(1) manual page.
_dddd_iiii_rrrr_nnnn_aaaa_mmmm_eeee delivers all but the last level of the pathname in _s_t_r_i_n_g.
