- Wait for your background process whose process id is _n and report its
- termination status. If _n is omitted, all your shell's currently active
- background processes are waited for and the return code will be zero.
-
- The shell itself executes _w_a_i_t, without creating a new process.

- If you get the error message _c_a_n_n_o_t _f_o_r_k, _t_o_o _m_a_n_y _p_r_o_c_e_s_s_e_s, try using
- the _w_a_i_t(1) command to clean up your background processes. If this
- doesn't help, the system process table is probably full or you have too
- many active foreground processes. (There is a limit to the number of
- process ids associated with your login, and to the number the system can
- keep track of.)
-
- BBBBUUUUGGGGSSSS
- Not all the processes of a 3- or more-stage pipeline are children of the
- shell, and thus cannot be waited for.
-
- If _n is not an active process id, all your shell's currently active
- background processes are waited for and the return code will be zero.
