Hard Link Manager - simple tool for create, find and remove hard links

Simple tool for create, find and remove hard links.

In computing, a hard link is a directory entry that associates a name with a file on a file system. (A directory is itself a special kind of file that contains a list of such entries.) The term is used in file systems which allow multiple hard links to be created for the same file. This has the effect of creating multiple names for the same file, causing an aliasing effect: e.g. if the file is opened by one of its names, and changes are made to its content, then these changes will also be visible when the file is opened by an alternative name. By contrast, a soft link on such file systems is not a link to a file itself, but to a file name. This also creates aliasing, but in a different way.

Directories are files, so multiple hard links to directories are possible; however, their unrestricted creation is usually avoided, because of the cyclic structures this may create.

Hard links—that is, multiple directory entries to the same file—are supported by POSIX-compliant and partially POSIX-compliant operating systems, such as Mac OS X.
