I have set my environmental variable $JAVA_HOME within the /etc/environment file. Worked like a charm! Now I want to remove it. After removing the line completely from the environment file, then do a reboot, it continues to resolve the path on:

The unset command will do this. From: Unix / Linux - Using Shell Variables
Unsetting Variables
Unsetting or deleting a variable directs the shell to remove the
variable from the list of variables that it tracks. Once you unset a
variable, you cannot access the stored value in the variable.
Following is the syntax to unset a defined variable using the unset
command −
unset variable_name
The above command unsets the value of a defined variable. Here is a
simple example that demonstrates how the command works −
#!/bin/sh
NAME="Zara Ali"
unset NAME
echo $NAME
