WAIT(1)

NAME
wait - wait for jobs to complete

SYNOPSIS
wait [-n | --any] [PID | PROCESS_NAME] ...

DESCRIPTION

wait waits for child jobs to complete.

If a PID is specified, the command waits for the job that the process with that process ID belongs to.

If a PROCESS_NAME is specified, the command waits for the jobs that the matched processes belong to.

If neither a pid nor a process name is specified, the command waits for all background jobs.

If the -n or --any flag is provided, the command returns as soon as the first job completes. If it is not provided, it returns after all jobs complete.

The -h or --help option displays help about using this command.
