WAIT(1) 						      General Commands Manual							   WAIT(1)

wait - await completion of process SYNOPSIS
Wait until all processes started with & have completed, and report on abnormal terminations. Because the wait(2) system call must be executed in the parent process, the Shell itself executes wait, without creating a new process. SEE ALSO
sh(1) BUGS
Not all the processes of a 3- or more-stage pipeline are children of the Shell, and thus can't be waited for. (This bug does not apply to csh(1).) 7th Edition April 29, 1985 WAIT(1)

wait -- await process completion SYNOPSIS
wait [pid] DESCRIPTION
If invoked with no arguments, the wait utility waits until all existing child processes in the background have terminated. Available operands: pid If a pid operand is specified, and it is the process ID of a background child process that still exists, the wait utility waits until that process has completed and consumes its status information, without consuming the status information of any other process. If a pid operand is specified that is not the process ID of a child background process that still exists, wait exits without waiting for any processes to complete. The wait utility exits with one of the following values: 0 The wait utility was invoked with no operands and all of the existing background child processes have terminated, or the process specified by the pid operand exited normally with 0 as its exit status. >0 The specified process did not exist and its exit status information was not available, or the specified process existed or its exit status information was available, and it terminated with a non-zero exit status. If the specified process terminated abnormally due to the receipt of a signal, the exit status information of wait contains that termination status as well. STANDARDS
The wait command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. BSD
