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 terminations.
       If  a  numeric  argument	 pid is given and is the process ID of a back‐
       ground process, waits until that process has completed.	Otherwise,  if
       pid  is	not  a	background process, exits without waiting for any pro‐
       cesses 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.

SEE ALSO
       csh(1), ksh(1), sh-posix(1), sh(1), wait(2).

STANDARDS CONFORMANCE
