wait(1)wait(1)Namewait - wait for process completion
Syntaxwait [pid]
Description
The command waits until all processes started with an ampersand (&)
have completed and reports on abnormal terminations.
If a numeric pid is given and is the process ID of a background
process, then waits until that process is completed. If pid is not a
background process, waits until all background processes have com‐
pleted.
Because the system call must be executed in the parent process, the
Shell itself executes without creating a new process.
Restrictions
Because not all the processes of a 3- or more-stage pipeline are chil‐
dren of the Shell, the command does not work on them.
The [pid] is available only with sh5.
