Linux notes: Link commands, soft links and hard links

Command name: LN
Function: Generate link file
directory where the command is located:/BIN/LN
Usage: LN [-S] Original file destination file
Parameters:
-S create a soft link (do not write this parameter to generate a hard link)

Soft Links:
Similar to shortcuts in Windows. It's just a link to the file it points to.
Hard links (The most important principle is that the hard link is the same as the I node of the original file):
A hard-link file is equivalent to copying a file that is identical to the original file, with the same file permissions, size, content, and the ability to synchronize updates. Hard links can continue to be used when the original file is lost.
Hard links cannot span partitions.
Hard links cannot be used for catalogs.
