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 filenameFor 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.confThen the variables and function will be accessible as depicted in the following example
echo $VAR1 $VAR2 $VAR3
hkong is leaving
test1
leaving is hkongThis command is most commonly used by startup scripts to import variables
and functions
