In most Unix and Unix-like systems, there are two kinds of "link". One is a "symbolic (or soft) link", and the other is a "hard link". Both of them are ways of pointing to a file or program that's in some other location in the file system than where it appears to be. (Another way to think of them is as "shortcuts".)A symbolic link can point to any location known to the system, whether it's physically part of the same file system or not. Hard links are generally limited to pointing to files within the same file system.
