Hard links and soft links in Linux

A hard link records the inode of the target, and the soft link records the path to the destination. Soft links are like shortcuts, and soft links are like backups. Soft links can do cross-partition links, and hard links because of the inode, can only be linked in this section, so soft links use more.

Their shortcomings:

Hard Links:

1, not allowed to create hard links to the directory

2. Links can only be created between files in the same file system

Soft Links:

A soft link can be any file or directory, a linked file can even link a nonexistent file, resulting in a "broken chain" problem, and can be linked to the loop itself.
