associative array - iterating over keys of indirect bash hash -


i writing script reads number of variables in config file. number of variables associative arrays. 1 or more of hashes need parsed @ runtime in order set number of session related parameters.

while can access values each key individually this:

declare -a $(echo $1)  . /path-to-config/script.conf  _hashid=$1 param=${_hashid_}[string] echo ${!param}

...i unable access keys themselves. i'd this:

declare -a $(echo $1)  . /path-to-config/script.conf  _hashref_=${1}[@] key in "${!_hashref_}" ;    echo ${_hashref_[$key]} done

this sets $key value of each element. , other variations i've tried on haven't worked either. can explain me how iterate on keys when hash name dynamic?

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
