A symbolic link is a pointer to another file or folder.

# windows
New-Item -ItemType SymbolicLink -Path "<link-path>" -Target "<real-path>"

# unix
ln -s "<real-path>" "<link-path>"

For some reason the previous command doesn't work correctly on Mac. Use this method.

cd "<linked-path-location>"
ln -s "<real-path>" <link-name>
