Answer 1

If you are looking to export only variables with a common prefix, e.g.:

BAZ_FOO="FOOFOO"
BAZ_BAR="BARBAR"

You could simply do this:

. foo.sh
variable_list=()
variable_list=( $(set -o posix ; set  |\
                  grep "BAZ_"         |\
                  cut -d= -f1) )
for variable in "${variable_list[@]}"
do
  export "$variable"
done
