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