Name
       wait - wait for process completion

Syntax
       wait [pid]

Description
       The  command  waits  until  all processes started with an ampersand (&)
       have completed and reports on abnormal terminations.

       If a numeric pid is given  and  is  the	process	 ID  of	 a  background
       process,	 then  waits until that process is completed.  If pid is not a
       background process, waits until	all  background	 processes  have  com‐
       pleted.

       Because	the  system  call  must be executed in the parent process, the
       Shell itself executes without creating a new process.

Restrictions
       Because not all the processes of a 3- or more-stage pipeline are	 chil‐
       dren of the Shell, the command does not work on them.

       The [pid] is available only with sh5.
