Aliases
Aliases are shortcuts to existing files or folders on your system. You can create them by right-clicking(Ctrl+Click) in the Finder on an existing file/folder, selecting the option “Make Alias”. This creates a shortcut that you can rename or move around without messing with the original.
Creating aliases in Terminal is extremely easy – just type in ln -s followed by the name of the file/folder you want to create the shortcut to, and by the name you want to give to the shortcut.
