I'm trying to install java-13 on Ubuntu 18.04 following this tutorial.
I've installed java-11 before which is preventing these commands taking effect
sudo mv jdk-13 /opt/ sudo tee /etc/profile.d/jdk13.sh <<EOF export JAVA_HOME=/opt/jdk-13 export PATH=\$PATH:\$JAVA_HOME/bin EOF source /etc/profile.d/jdk13.sh
type java command gives this
java is hashed (/usr/bin/java)
I guess this is due to some setting in some environment variables config file e.g. $HOME/.profile.
How do I know which file is overwriting my
I also tried this command
java -version Command 'java' is available in '/usr/bin/java' The command could not be located because '/usr/bin' is not included in the PATH environment variable.
