NAME

       wait - await process completion

SYNOPSIS

       [pid]

DESCRIPTION

       If  no argument is specified, waits until all processes (started with of the current shell have completed, and reports on abnormal termina-
       tions.  If a numeric argument pid is given and is the process ID of a background process, waits until that process has  completed.   Other-
       wise, if pid is not a background process, exits without waiting for any processes to complete.

       Because the system call must be executed in the parent process, the shell itself executes without creating a new process (see wait(2)).

   Command-Line Arguments
       supports the following command line arguments:

	      The unsigned decimal integer process
			  ID of a command, whose termination is to wait for.

WARNINGS

       Some processes in a 2-or-more-stage pipeline may not be children of the shell, and thus cannot be waited for.
