This is what I am looking at in a sh script

echo export jail_${jailname}_hostname=\"${jailname}\"
puts it into the env
and this brings it back out
eval jailname=\"\$jail_${jailname}_hostname\"

Question is how can I display from the console command
line what has been exported?

env issued on the console command line does not show
any thing named jail.
