iterate over a map and export vars

this script prints out the right values but it looks like my export statement isn't correct:

declare -A ENVMAP=( [foo]=bar [baz]=quux [corge]=grault )
for i in "${!ENVMAP[@]}"
do
  echo "key  : $i"
  echo "value: ${ENVMAP[$i]}"
  export "$i"="${ENVMAP[$i]}"
done

The value gets printed correctly so the map works but the vars aren't getting exported. Whats wrong with my export statement?

In case you want to have these vars permanently in your user's system you could add them into your current user's DOT/BASH profile too, few steps are as follows:

I- Go to current user's directory by doing normal cd.

II- Then list all files including hidden ones by doing either ls -la or ls -lhtr.

III- Now either add these export commands in your BASH profile(in case you are on Linux/bash) or you could create your own .profile too(only one will be picked up at a time).

IV- Once you saved it then use source .profile or source .bash_profile or . ./.profile or . /.bash_profile.

Please try these and let me know if these helps you.

How are you running the script? the exported variables are visible to the child processes of your script but not to the parent, i.e. your bash console.
