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 com-
pleted, 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.
SEE ALSO
csh(1), ksh(1), sh-posix(1), sh(1), wait(2).
STANDARDS CONFORMANCE
wait: SVID2, SVID3, XPG2, XPG3, XPG4, POSIX.2
