Nope.

The .version file location has moved to <install root>/sdk/<nugetversion>/.version from <install root>/.version.

there is no way of reliably checking versions right now since there is more than one versioned folder inside zip. I will fix it once this story is figured out

@krwq this should now be possible as of dotnet/cli#2022

http://dotnetcli.blob.core.windows.net/dotnet/beta/dnvm/latest.sharedfx.osx.x64.version

Would really speed up dev cycles with this in 😄

Should be solved with dotnet/cli#2041
