I'm a bit confused ...
If I have assoc-array:

 declare -A foo=([one]=11 [two]=22)

and am passing name in another var, like "fee"

 fee=foo

I tried echoing the val:

 echo ${!fee[one]}

but got nothing -- tried a few other syntaxes.
    

This has come up a number of times. Here's a message from 2002 explaining
the details:

I see....but that begs the question, how do you access an array's
members using a var holding the array's name?

I wanted to be able to do something like have a set of
values in an assoc. map, and pass the name to a generic
processing routine with the map name as a param, like:



sub processSrvState() {
   my stat=${1:?}
   if [[ ${!stat[cur_up]} == ${!stat[max_up]} &&
     ${!stat[cur_down]} == ${!stat[max_down]} ]]; then
     ...
   fi

but it seems less than straight-forward.  Is this possible?

I can likely think of ways around it, but none are very str8-forward
or attractive....(sigh)...
Tnx & tnx for the pointer...
