¿Hay alguna manera de cambiar rápidamente todas las alternativas relacionadas con Java usando update-alternatives
?
Por ejemplo, si quiero cambiar Java a 7, ejecuto sudo update-alternatives --config java
y selecciono Java 7 OpenJdk. Pero si corro update-alternatives --get-selections | grep java
me sale lo siguiente,

Como puede ver, mi alternativa Java se cambió a 7, pero no se cambió ninguna otra alternativa basada en OpenJDK 6. Claro que podría cambiar cada uno manualmente o escribir un script para hacerlo, pero supongo que hay una mejor manera de lograr esto.
update-java-alternatives
cambia todas las demás alternativas de Java, incluso cuando la configuración del complemento arroja un error.
