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) &

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.
LIMIT=10 # Or whatever sleep `expr $RANDOM % $LIMIT + 1`

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.

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

sleep $(($RANDOM%300))
