Bill,
This seems to work (credit to Advanced Bash-Scripting Guide, section
16.1, "Using exec"):
#!/bin/bash
cat >/tmp/junkfile <<-"CODE"
line 1
line 2
line 3
CODE
declare -a RULES
i=0
j=4
exec 6<&0 # Link file descriptor # 6 with stdin
exec </tmp/junkfile # stdin replaced by /tmp/junfile
read RULES[0]
read RULES[1]
read RULES[2]
echo ${RULES[0]}
echo ${RULES[1]}
echo ${RULES[2]}
rm -r /tmp/junkfile
exec 0<&6 6<&- # Restore stdin from fd #6
echo -n "Enter data: " # Test restore
read b1
echo $b1
John
