Linux export command not working

Question

I have created a shell script in linux which uses export commands to set paths and classpath. But paths and classpath are not getting set correctly as shown below. Below is the part of script

Input:

export JAVA_HOME=/usr/java/latest

export CLASSPATH=$JAVA_HOME/lib

echo $CLASSPATH

Output

/lib/java/latest.

It should be /usr/java/latest/lib. Please can someone tell me where I'm wrong or why it is returning wrong output.

Answer 1

You need to source the script where you are setting the variables

source your_script_name

Or another way of sourcing is by executing your script as follows:

. ./your_script_name

Make sure there is space in between 2 dots
