What is the difference between Hard Link and Soft Link in Linux January 14, 2011Posted by Tournas Dimitrios in Linux.
Hard link: Hard link refers to “The specific location of physical data”.
- Hard Link is a mirror copy of the original file.
- Hard links share the same inode.
- Any changes made to the original or Hard linked file will reflect the other.
- Even if you delete any one of the files, nothing will happen to the other hard links.
- But soft link which points to deleted hard link become a dangling soft link.
- You can’t link a directory even within the same file system.
- Hard links can’t cross file systems.
Soft link( also called symbolic link): Soft link refers to “A symbolic path indicating the abstract location of another file”.
- Soft Link is a symbolic link to the original file.(more like windows shortcuts)
- Soft Links will have a different Inode value.
- Any changes made to the soft link will reflect the original file and its hard links.
- A soft link points to the original file. If you delete the original file, the soft link fails. It would become dangling symbolic link.
- If you delete the soft link, nothing will happen.
- You can link a directory using soft link on same file system and also on other file system.
- Soft links can cross file systems
