What is the difference between a hard link and a symbolic link?
A hard link then just creates another file with a link to the same underlying inode. When you delete a file it removes one link to the underlying inode. The inode is only deleted (or deletable/over-writable) when all links to the inode have been deleted. A symbolic link is a link to another name in the file system.
What happens when you change a symbolic link?
Since the symbolic link is a link that directs to the original file, changing the symboliclink should change the original file. What will break a symbolic link is when the original file is moved to a different file or deleted. So symbolic links can be seen as a static link to the last known location of the original file.
What is the difference between a symbolic link and a target?
Symbolic link. A symbolic link is a file-system object that points to another file system object. The object being pointed to is called the target. Symbolic links are transparent to users; the links appear as normal files or directories, and can be acted upon by the user or application in exactly the same manner.
When does an inode symbolic link get deleted?
The inode is only deleted (or deletable/over-writable) when all links to the inode have been deleted. A symbolic link is a link to another name in the file system.
A hard link is a link that co n nects many files with the same inode, so the same data block is shared with these files. A change in the data of a file will reflect on the others. If the original file is deleted, the hard link still exists as long as there is a file linked to the inode.
How to delete or replace an already created symbolic link?
To add to all answers above, a symbolic link can be treated as a regular file in many cases (the link, not the target). rm on a symbolic link will remove it. If the link is owned by root, you will need to sudo. You should be able to rm /usr/bin/ns or rather sudo rm /usr/bin/ns don’t forget ownership.
Can you change the location of a hard link?
By using a hardlink, you can change the original file’s contents or location and the hardlink will still point to the original file because its inode is still pointing to that file. There is no referencing to the original file.
How is a hard link like a file?
A hard link, in fact, is just like the original file pointing to the same hard disk location as original one. In that sense, a newly created file is also a hard link. But when we create a hard link of an existing file, then we are effectively creating a second hard link of the same data.
