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 back-
       ground process, waits until all background processes have completed.

       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 children of the Shell, the command does not work on them.

       The [pid] is available only with sh5.
