Today I've just downloaded "dotnet-dev-osx-x64.1.0.0-preview1-002702.pkg" and installed it. After that I tried "dotnet" command in my terminal, nothing printed.
I also tried Spotlight searching, seems nothing found.
Where is this package installed at all?
The key thing is you need to locate the file dotnet.exe, then create a new Symbolic link to create a new shortcut link to that dotnet.exe file in the usr/local/bin folder. Sometimes you see this error "/usr/local/bin//dotnet: File exists", it means the link already exists in that folder (and it's normally a faulty one), to fix that you need to go to that folder and delete the link.
After you have located the dotnet.exe file, in my case it's in the '/usr/local/share/dotnet/dotnet' folder. Create a new symbolic link for it using this command:
ln -s /usr/local/share/dotnet/dotnet /usr/local/bin/
Done! You can run the "dotnet" command now...Hope it helps
