Difference between hard and soft link? |
Hard links points to the inode, which points has the info of where the file is in the disk. If you have a file and create a hard link, and delete the original file, you will still have the contents in the hard link because to actually delete the file the inode has to be left with no reference. Soft links are a reference to a path, not to an inode. If you move or delete the original file from its path, the soft link points to nothing. |
