update-alternatives --install

update-alternatives --install is a command used in Linux systems to add or update the alternatives for a particular command or executable file.

The syntax for using this command is:

update-alternatives --install <link> <name> <path> <priority>

where:

• <link> is the symbolic link to be created or updated.
• <name> is the name of the alternative.
• <path> is the path of the actual executable file.
• <priority> is a number used to determine the default alternative.

For example, if you want to add an alternative for the editor command, you can use the following command:

sudo update-alternatives --install /usr/bin/editor editor /usr/bin/vim 100

This command creates a symbolic link /usr/bin/editor that points to the executable file /usr/bin/vim and sets the priority to 100.

You can then use the command update-alternatives --config editor to select the default editor from the available alternatives
