option is supplied, no path search is performed, and _f_i_l_e_n_a_m_e is
used as the full file name of the command. The --rr option causes
the shell to forget all remembered locations. The --dd option
causes the shell to forget the remembered location of each _n_a_m_e.
If the --tt option is supplied, the full pathname to which each
_n_a_m_e corresponds is printed. If multiple _n_a_m_e arguments are
supplied with --tt, the _n_a_m_e is printed before the hashed full

printed. The return status is true unless a _n_a_m_e is not found

Each time hhaasshh is invoked, the full pathname of the command _n_a_m_e
is determined by searching the directories in $$PPAATTHH and remem-
