Topic: Hard link

	Hard Link
		This is in fact a hard link, but most people usually associate "hard linking" to be the creation of additional directory entries for an existing object.
		Therefore, the creation of a subdirectory creates a new hard link to the parent, and two new hard links to the new object: one from the parent, and one from its own dot entry.
		Depending on the kernel, the decision to allow a directory hard link may be deferred to the filesystem module itself.

	Hard link - Wikipedia, the free encyclopedia
		In computing, a hard link is a reference, or pointer, to the physical data on a volume.
		Hard links can only refer to data that exists on the same file system.
		If all of the links are removed and no process has the file open, then the space occupied by the data will be considered free, allowing it to be reused in the future for other files.

		A symbolic link or hard link to a computer file, associating a filename with another file or a file's data.
		A verb "to link", which in computer science means to assemble object files and libraries into an executable file or library.
		A link is often referred to as one object of several identical objects "linked" together.

	ITworld.com - UNIX SYSTEM ADMINISTRATION - When Hard Links Won't Do the Job
		Hard links are often used to make "copies" of files without having to allocate additional disk space and without concern that the "copy" and the original file will get out of synch.
		Hard linking gives an executable the opportunity to invoke a different character depending on how it is called, while still sharing a good deal of common code.
		A hard link is a duplicate of a file, another reference in the file system; hard linking a symbolic link will, therefore, create another symbolic link and, if the relative location is not valid from the new link's location, then the link will be "dangling" (i.e., pointing to something which doesn't exist).

		Hard links to the same file are indistinguishable from each other except that they have different pathnames.
		Normally all hard links to a file must be in the same {file system} because a directory entry just relates a pathname to an inode within the same file system.
		The space associated with a file is not freed until all the hard links to the file are deleted.

	The Answer Gang 93: hard links
		If there are more than one hard links to a file or directory, the file remains, so although we regard the rm command as deleting a file, it only deletes the link to the file.
		When there are no hard links to a file or directory, the file system will then free up the actual space used by the file.
		ISTR that hard links to directories can only be created by mkdir to ensure that we can't build up cyclic directory structures, otherwise programs such as find, which traverse the directory could loop over the same directory structure for ever.

		The standard ln command does not usually allow you to create a hard link to a directory, chiefly because the standard rm and rmdir commands do not allow you to delete such a link.
		The restrictions on hard links to directories and between file systems are very common but are not mandated by POSIX.
		Symbolic links are often used instead of hard links because they do not suffer from these restrictions.

		NTFS Link is a Windows Shell Extension, which hooks into Windows Explorer, providing extended functionality for creating and using hard links, as well as junction points on NTFS file systems.
		A hard link is the file system representation of a file by which more than one path references a single file in the same volume.
		As you can see, compared to hard links, soft links have a drawback: If the target folder is deleted/moved/renamed, all the links to it will stop working, as the path they have attached is then invalid.

	LWN: More notes on reiser4
		Note that hard linking from inside a chroot to main system files (such as /bin/bash) is not a very smart thing to do, as chrooted users can then modify exactly the files you wanted to prevent them from modifying.
		I suppose what is meant is, that with symbolic links there is a distinction between the actual file and the link: removing the symbolic link leaves the file intact, while removing the file leaves you with a link pointing nowhere.
		With hard links, you merely remove one of the references to the file (this is a number in the inode that is increased whenever a hard link is created), leaving it intact until the last link is removed.

		Hard links were developed before soft links, both are actually short cuts to the physical file.
		Soft links were developed to to enable files to be linked across file systems and hard disks, something which cannot be done with hard links.
		Hard links do not depend on the initial filename being present whereas soft links refer to nothing if the initial filename is removed.

		They have two important limitations: a hard link can't cross a filesystem (i.e., both filenames must be in the same filesystem), and you can't create a hard link to a directory (i.e., a directory can only have one name).
		With a hard link, the two filenames are identical in every way.

		The first link to a file is referred to as the primary link and is distinguished by having the directory ID and name of the link stored in the file header.
		Additional links are either aliases or hard links, depending on whether the volume on which the file resides has hard links enabled or disabled.
		If hard links are not enabled and you have not created an alias for a file, only one link to that file exists: the primary link.

		You can't hard link directories, although there may be no problem with hard linking the access files.
		It is reasonable that all the scripts could be on the same partition, so hard links should be OK for that.

		The trouble is that when the backup was taken, there appears to have been a /sbin/sh process running which creates a hard link to /sbin/sh under /proc.

	FILE_LINK (Site not responding. Last check: 2007-10-03)
		All files carry a reference count that contains the number of hard links that point to them; deleting a link to a file does not remove the actual file from the filesystem until the last hard link to the file is removed.
		Hard links may not span filesystems, as hard linking is only possible within a single filesystem.
		Hard links may not be created between directories, as doing so has the potential to create infinite circular loops within the hierarchical UNIX filesystem.

		An NTFS hard link is similar to a POSIX hard link.
		Additional hard links, created with the HardLink function, allow you to have multiple directory entries for a file, that is, multiple hard links to the same file.
		Because hard links are just directory entries for a file, whenever an application modifies a file through any hard link, all applications using any other hard link to the file see the changes.

		A hard link protects the contents of a file from being lost (because it counts as one of the names of the file).
