For the sake of convenience, you can use hard links to create additional file names for a file. Links must be created on an NTFS file system partition by a user who has administrator access.
You create links with the ln(1) command. The following commands create a link called calculator that points to the Win32 calc.exe file. After entering these commands, you can start the calc.exe program by typing calculator.
cd /dev/fs/C/WINNT/system32
ln calc.exe calculator
If many users use one computer running Interix, you can place all of your links into a standard directory that already exists in every user's PATH. This makes it easier for users to start programs.
Although links are convenient, creating too many can make it difficult to manage them. They should therefore be used judiciously.
