nvs link [version]
nvs ln [version]
Creates a symbolic directory link at $NVS_HOME/default that points to the specified version (or the current version from PATH at the time of the command). This sets a "default" node version, which is restored whenever the current version is removed, or when running nvs use with no version. It can also be useful when there is a need to configure a fixed path elsewhere (such as in an IDE), allowing the version to be switched without changing the path.
On Windows, this command also updates the profile PATH environment variable to include the default (linked) version, so that any newly opened shells will use that default version.
On non-Windows platforms when a new shell sources the nvs.sh script it also sets PATH to include the default (linked) version, if a link is present.
When NVS is installed to a system directory, linking a node version also creates symbolic links at %ProgramFiles%\nodejs or /usr/local/bin, if there is not already a system-installed Node.js there.
