Hey Rick!

 RS> So If I make a script that performs something and then it calls
 RS> say another script, would the first script then pause until the
 RS> called side script completes?

That is the normal behavior.

 RS> If not is there a way to make it wait to move forward until the
 RS> other one completes?

-={ '<Esc>:read !wait --help' starts }=-
wait: wait [-fn] [-p var] [id ...]
    Wait for job completion and return exit status.
    
    Waits for each process identified by an ID, which may be a process ID or a
    job specification, and reports its termination status.  If ID is not
    given, waits for all currently active child processes, and the return
    status is zero.  If ID is a job specification, waits for all processes
    in that job's pipeline.
    
    If the -n option is supplied, waits for a single job from the list of IDs,
    or, if no IDs are supplied, for the next job to complete and returns its
    exit status.
    
    If the -p option is supplied, the process or job identifier of the job
    for which the exit status is returned is assigned to the variable VAR
    named by the option argument. The variable will be unset initially, before
    any assignment. This is useful only when the -n option is supplied.
    
    If the -f option is supplied, and job control is enabled, waits for the
    specified ID to terminate, instead of waiting for it to change status.
    
    Exit Status:
    Returns the status of the last ID; fails if ID is invalid or an invalid
    option is given, or if -n is supplied and the shell has no unwaited-for
    children.
-={ '<Esc>:read !wait --help' ends }=-

Of course you only need to do this when the script is running parallel processes where the output from one is needed for another.

Life is good,
Maurice
