Soft links and hard links under Linux

Hard Links

You can delete any one of the two files without being affected by a file alias.

Directory cannot be a hard link to a directory

You can only do hard links under the same partition, not across partitions

How to use:

Ln-i/root/1.txt/tmp/2.txt (A hard link to 1.txt under root, connected to 2.txt under TMP)

Soft links

Equivalent to a shortcut on the desktop

Soft links can be made across partitions

Files can be soft links, directories can also do soft links

How to use:

Ln-s/root/12.txt/tmp/23.txt (a soft link to the 12.txt file under root, linked to the 23.txt under TMP)

Attention:

Soft links can be soft links, but after removing the middle soft link, the last soft link is not available
