Hello again!

Today, we are going to learn about hard or simple links on a POSIX system.

What is a hard link?

A hard link is used by a root mode. Be careful with EOACCESS. We recommend soft links, this links are user mode.

What is a user mode?
A user mode is a link made by our account on the system. With soft link, we can build several links of the original binary or text file.

Example:
sudo ln -s /home/user/text.txt user1.txt

This example is very back because can be an EOACCESS error.

Soft link:
ln -s /home/user/text.txt /home/user/text1.txt

With soft links we can make more links, it’s easier.
