Soft links can be linked across different file systems, although if the original file is deleted or moved, the soft linked file will not work correctly (called hanging link). As similar to hard links, any changes to the data in either file is reflected in the other. Each soft linked file contains a separate Inode value that points to the original file.

A soft link is similar to the file shortcut feature which is used in Windows Operating systems.The disadvantage of hard links is that it cannot be created for files on different file systems and it cannot be created for special files or directories.The size of any of the hard link file is same as the original file and if we change the content in any of the hard links then size of all hard link files are updated.If original file is removed then the link will still show the content of the file.We cannot create a hard link for a directory to avoid recursive loops.Even if we change the filename of the original file then also the hard links properly work.Removing any link, just reduces the link count, but doesn’t affect other links.

ls -l command shows all the links with the link column shows number of links.Hard links more flexible and remain linked even if the original or linked files are moved throughout the file system, although hard links are unable to cross different file systems. Each hard linked file is assigned the same Inode value as the original, therefore they reference the same physical file location.Basically hard link increases reference count of a location while soft links work as a shortcut (like in Windows) But if we create a soft link of the file and then delete the file, we can’t access the file through soft link and soft link becomes dangling. If we create a hard link to the file and then delete the file, we can still access the file using hard link. Symbolic links are not updated (they merely contain a string which is the path name of its target) hard links always refer to the source, even if moved or removed.įor example, if we have a file a.txt. These links behave differently when the source of the link (what is being linked to) is moved or removed. Links allow more than one file name to refer to the same file, elsewhere. Creating links is a kind of shortcuts to access a file. Like pointers in any programming languages, links in UNIX are pointers pointing to a file or a directory.
