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.
