What does "only when sourcing script" mean?

Steps to reproduce

curl -sSL https://raw.githubusercontent.com/dotnet/cli/rel/1.0.0-preview2/scripts/obtain/dotnet-install.sh | bash /dev/stdin --version 1.0.0-preview2-002996 --install-dir ~/dotnet

Expected behavior

I understand messages that it prints.

Actual behavior

dotnet-install: Downloading https://dotnetcli.blob.core.windows.net/dotnet/preview/Binaries/1.0.0-preview2-002996/dotnet-dev-centos-x64.1.0.0-preview2-002996.tar.gz dotnet-install: Extracting zip dotnet-install: Adding to current process PATH: /home/bb/dotnet. Note: This change will be visible only when sourcing script. dotnet-install: Installation finished successfuly.

Environment data

dotnet --info output:

 [bb@bb-centos72-3 ~]$ dotnet --info
-bash: dotnet: command not found

Or, more usefully:

[bb@bb-centos72-3 ~]$ ./dotnet/dotnet --info

@dazinator the best way is to set the -InstallDir (see doc) and add this direcotry to the $PATH.

As alternative create a symlink: ln -s $installdir/dotnet /usr/local/bin. Where $installdir is the given installation directory from above.

It’s 2018 and it still does not add to the path, I tried the chmod +x, executing as bash ./dotnet-install.sh1, etc (see referenced issue 9234 above). Can you not give an example that does work in the message?
