 Is there a way I can sleep random length to time before executing each
 but background each one so master script returns promptly.  Something
 like.

sleep 15  perl /scripts/create_graph.pl 
should return promptly, another reply addresses the random part.

Don't background them individually; background the whole lot

#!/bin/sh
(
  perl /scripts/create_graph.pl
  perl /scripts/create_graph_out.pl
  etc
) 

Now they will run one after another and you don't need to sleep
between them.

I have a script file in my cron.hourly that contains a good number of scripts I 
must call.

#!/bin/sh

sleep 15
perl /scripts/create_graph.pl 

sleep 15
perl /scripts/create_graph_out.pl 

many more lines. etc.

Is there a way I can sleep random length to time before executing each but 
background each one so master script returns promptly.  Something like.

sleep (random 1 - 300 seconds, perl /scripts/create_graph_out.pl)

If you are trying to avoid running all these perl scripts concurrently
set up the perl scripts to accept an argument, then pass each one a time
delay when you call them.

PerlScript-1 20 
PerlScript-2 40 
...
PerlScript-n n*20 

The calling script will return almost immediately but the perl scripts
will delay any action for the specified time.  That way the time delay
is fully adjustable from zero to forever.
