update-alternatives

A convenient tool for maintaining symbolic links to determine default commands.

  • Add a symbolic link:

sudo update-alternatives --install {{path/to/symlink}} {{command_name}} {{path/to/command_binary}} {{priority}}

  • Configure a symbolic link for java:

sudo update-alternatives --config {{java}}

  • Remove a symbolic link:

sudo update-alternatives --remove {{java}} {{/opt/java/jdk1.8.0_102/bin/java}}

  • Display information about a specified command:

update-alternatives --display {{java}}

  • Display all commands and their current selection:

update-alternatives --get-selections
