here is my vars file setting

# (such as /etc/openvpn) so that your
# edits will not be wiped out by a future
# OpenVPN package upgrade.

any help will be appreciated

Answer 1

If you notice there are 7 command not found statements before the echo. There are also 7 "empty" lines before the echo. It appears that the key dir variable is properly expanding in the echo statement. After the echo statement there are 5 "empty" lines and 5 more command not found errors. This makes me think that the command not found statements are a result of the "empty" lines.
Obviously if the line is empty it shouldn't cause that sort of an error. How did the "vars" file get there? Did you copy/paste it and invisible characters got copied in the process? Or perhaps it was edited on a device that used a different type of carriage returns?
You should use an editor such as vim on it which will help you see normally hidden characters. You could also try to use a program like tofrodos to convert the carriage returns. When you source a file you are actually executing a script and any variables exported become part of our shell that sourced it in. Normally scripts would conform to unix line endings.
