     _S_y_s_t_e_m causes _s_t_r_i_n_g to be given to your shell as input as
     if the string had been typed as a command.  If environment
     variable SSHHEELLLL is found, its value will be used as the com-
     mand interpreter (shell); otherwise _s_h(1) is used.

     The current process waits until the command terminates.  The
     returned value will be the exit status of the shell.  See
     _w_a_i_t(2) for an explanation of this value.
