One Linux Command 10 and one Linux Command 10 every day

File Processing Command: ln
Command name: ln command name: link
Syntax: ln-s [original file] [target file]
-S: Create a soft connection
Function Description: generate a link file.

# Ln-s/etc/issue/tmp/issue. soft
Create a soft link for the file/etc/issue/tmp/issue. soft
# Ln/etc/issue/tmp/issue. hard
Create/etc/issue hard link/tmp/issue. hard

[Root @ localhost tmp] # ls-I/etc/issue. hard issue. soft
668057/etc/issue 668057 issue. hard 407192 issue. soft
As you can see, the hard link has the same node number as the original file, and the soft link is equivalent to the shortcut of the windows system! The hard link is synchronized with the original file!

Hard links cannot span partitions and cannot be used for directories. They can be identified by I nodes.
