Linux hard link and soft link

The hard link records the inode of the target, and the soft link records the path of the target. Soft links are like shortcuts, while soft links are like backups. Soft links can be used as cross-partition links, while hard links can only be used as links in this partition due to inode, so more soft links are used.

Their disadvantages:

Hard link:

1. Hard links cannot be created for directories.

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

Soft link:

A soft link can be any file or directory, a linked file or even a file that does not exist. As a result, a "broken chain" problem occurs and you can link yourself cyclically.
