NAME [Toc] [Back]
wait - await process completion
SYNOPSIS [Toc] [Back]
wait [pid]
DESCRIPTION [Toc] [Back]
If no argument is specified, wait 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 background process, wait waits until that process has
completed. Otherwise, if pid is not a background process, wait exits
without waiting for any processes to complete.
Because the wait() system call must be executed in the parent process,
the shell itself executes wait without creating a new process (see
wait(2)).
Command-Line Arguments [Toc] [Back]
wait supports the following command line arguments:
pid The unsigned decimal integer process ID of a command,
whose termination wait is to wait for.
WARNINGS [Toc] [Back]
Some processes in a 2-or-more-stage pipeline may not be children of
the shell, and thus cannot be waited for.
