If you have a lot of variables set in a configuration file and you need to access all those variables quickly, you can try to use

source filename

For example, you have a configuration file named /etc/vars.conf with the following content:

VAR1=hkong

VAR2=is

VAR3=leaving

function test1 {

echo $VAR3 $VAR2 $VAR1

}

You can then invoke

source /etc/vars.conf

Then the variables and function will be accessible as depicted in the following example

echo $VAR1 $VAR2 $VAR3

hkong is leaving

test1

leaving is hkong

This command is most commonly used by startup scripts to import variables

and functions
