Overview
alternatives
Obtain the Alternatives for an Executables
alternatives --display java
alternatives --display java | grep priority
The output contains the "alternatives" - which include the full path of the executable and a priority.
Set an Alternative Interactively
alternatives --config java
Set an Alternative Non-Interactively
The following command seems to work:
alternatives --set java /usr/lib/jvm/java-1.8.0-amazon-corretto/jre/bin/java
The exact path can be obtained with --display. The command is sensitive to the exact absolute path of the "alternative" executable.
On some occasions, for example Amazon Linux 2, alternatives --set failed:
alternatives --set java /usr/lib/jvm/amazon-corretto-8.292.10.1-linux-x64/bin/java /usr/lib/jvm/amazon-corretto-8.292.10.1-linux-x64/bin/java has not been configured as an alternative for java
