Delay is not the point, you start all independent tasks and then dependent tasks for each are arranged to wait for all their precedents. Now, only one process can wait for each running process, so if many processed need to know what is done, a log file, directory of marker files or other database can track progress, and you can check progress in a loop every N seconds. You could write a supervisor that knows the prereqs of every new process. You could put the prereqs in a SQL db, same db as the completions, so you can query what is not run and no prereq is missing, and launch any found. You would be writing ControlM or Tivoli TWS and such.

NAME
shell - run a command using shell SYNOPSIS
shell command [command] ... DESCRIPTION
The shell function concatenate its arguments, separating each by a space, and passes this string to the shell ($SHELL if set, otherwise /usr/bin/sh). EXAMPLES
Example 1: A sample output of shell command. Since the Form and Menu Language does not directly support background processing, the shell function can be used instead. `shell "build prog > /dev/null &"` If you want the user to continue to be able to interact with the application while the background job is running, the output of an exe- cutable run by shell in the background must be redirected: to a file if you want to save the output, or to /dev/null if you don't want to save it (or if there is no output), otherwise your application may appear to be hung until the background job finishes processing. shell can also be used to execute a command that has the same name as an FMLI built-in function. NOTES
The arguments to shell will be concatenate using spaces, which may or may not do what is expected. The variables set in local environments will not be expanded by the shell because "local" means "local to the current process." ATTRIBUTES
