NAME

wait — await process completion

SYNOPSIS

wait [pid]

DESCRIPTION

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

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

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

STANDARDS CONFORMANCE

wait: SVID2, SVID3, XPG2, XPG3, XPG4, POSIX.2
