I have multiple Amazon EC2 accounts and want to quickly be able to switch variables, such as $EC2_HOME$EC2_HOME, using a script.

I have have a shell script set up like this:

#!/bin/sh export EC2_HOME=/home/me/.ec2 echo $EC2_HOME

When I run the script I know that EC2_HOMEEC2_HOME is set, but I thought that using export would make the variable stick around after the script completed. It does not, as running echo $EC_HOME does not show anything.

I know this must be very rudimentary Linux scripting knowledge, but I don't know it. I tried looking for related questions without luck - so my apologies if this is a duplicate.
