What is the function of the “ln” command in Ubuntu?

In Ubuntu, the ln command is used to create hard links or symbolic links. It has two main functions.

1. Creating a hard link: The ln command can be used to create a hard link, which shares the same data block as the original file. Even if the original file is deleted, the hard link can still access the data. The command format for creating a hard link is: ln [options].
2. Create symbol link: Use the ln command to create a symbolic link, also known as a soft link. A soft link is a shortcut to the original file and will become invalid if the original file is deleted. The command format for creating a soft link is: ln -s
