bash - Parse configuration remote configuration file -

i want read in remote configuration file in bash script; locally following works fine:

while ifs="=" read -r name value;     declare "$name=$value" done < "$cfg" 

i tried same using ssh , cat:

ssh "$hostname" "cat $remote_cfg" | while ifs="=" read -r name value;     declare "$name=$value"     echo $name $value done 

but variables declared in scope of while loop, how can bring them outer scope?

thanks in advance!

i have figured things out (source: http://mywiki.wooledge.org/bashfaq/024).

process substitution works:

while ifs="=" read -r name value;     declare "$name=$value" done < <(ssh "$hostname" "cat ~/.cuttleline.cfg")
